  • 2 Gas vs Electric String Trimmers

Why choose a battery powered string trimmer?

There are a few reasons why you might want to choose a battery powered string trimmer or a battery powered weed eater over a gas string trimmer or weed eater.

Mar 08, 2020 We do have some concerns with the battery life so you may want to purchase a spare, but other than that this is a great machine that’s worthy of the title best runner up cordless string trimmer. If you’re looking for a good budget cordless string trimmer, the Worx WG170 is worth consideration. This machine retails for under. Dec 23, 2020 Vibration control has come a long way for the best battery-powered weedeater models. All of the ones we recommend have acceptable levels, but a few of them really struggled in earlier generations. When you pick up a weedeater and pull the trigger, feel for how much vibration makes it to your hands and how rough the drive seems to be.

  • starts easily and every time
  • lighter weight
  • no mixing of fuel
  • no fuel storage
  • much quieter than gas trimmers

I personally switched to all electric outdoor equipment recently and I am not looking back.

Gas vs Electric String Trimmers

So what are the major differences between gas and electric trimmers then? I would say the major difference is convenience. Electric string trimmers are much easier to deal with. I am sure if you have used a gas powered string trimmer in the last decade, you have had to deal with mixing fuel.

Mixing the Gas

With an electric trimmer, there is no gas or oil or anything like that to deal with, so all you really have to do is make sure your battery is charged. Did I mention how convenient battery powered outdoor tools can be?

Not that mixing gas takes an aerospace engineering degree, but it is a pain. This usually reared its head when I had to go to the local home center and buy those small bottles of oil to mix up the gas. I never seemed to have one when I needed it. Even when I got it mixed there was no guarantee it would start.

Why won’t this thing start?

So electric string trimmers always start, because all you have to do is put a battery in or plug it into the wall and pull the throttle trigger.

Gas trimmers can be extremely hard to start. If your fuel has been sitting too long, or you forgot to add an Ethanol additive to your fuel, then starting the trimmer can be a real pain. Anyone ever broke a recoil starter? I have.

Gas Trimmers are so Loud

So now you have the trimmer started, but it sounds like a go cart running at top speed. No trimming for you early in the morning when the temps are nice an cool. The neighbors won’t like that. Also, don’t forget about that exhaust smell.

Electric trimmers, for the most part, are quieter, I won’t say quiet. You have the whirling noise of the string as it spins, but you don’t have the high pitched whine of the motor.

Gas Trimmers are Heavy

You’re trimming away at your landscaped beds or sidewalks, and you start to feel your arms getting tired, and you’re only halfway through trimming. My old gas trimmer weighed a ton, not literally, but it was heavy. I had to eventually give in and use a shoulder strap to offset the engine weight.

My electric trimmer, on the other hand, is not heavy. I do have a motor and battery to contend with, but compared to my old gas trimmer, this thing is light. The great thing is I didn’t experience a loss of power when switching to a battery powered trimmer, you can’t beat lightweight and powerful. I can easily cut the same amount of weeds, tall grass, and over grown grass on a single charge. Having an extra battery on hand just extends the runtime.

Best Battery Powered String Trimmer for 2021

So hopefully I have at least convinced you to consider a battery powered string trimmer as your next trimmer choice. Below in no particular order are five of the best battery powered string trimmers available in 2021.

RYOBI makes a larger assortment of electric lawn and outdoor power equipment, and I own quite a few of their products. This 40 volt straight shaft string trimmer has all the power of a gas model, with non of the gas powered headaches. The trimmer has an impressive 13 in. to 15 in. cutting width, and has a bump feed head for getting more trimmer string when you need it. The biggest advantage this trimmer has over the other in this list is the expand-it attachments with making this not just trimmer, but a blower, pole saw, hedge trimmer, and many other tools. This is also one of the more affordable options that has excellent power.

  • Gas like power
  • Attachment capable: accepts RYOBI expand-it attachments and other universal gas attachments to save time, money, and space
  • Premium 0.080 in. twisted dual line
  • Reel-easy bump-feed string head for fast and easy reloading
  • Variable speed trigger for cutting control
  • 13 in. to 15 in. adjustable cutting width

What We Liked

  • Attachment capability – being able to add attachments to this trimmer is a great bonus
  • Bump feed head with fast reloading – the ability to easily reload trimmer line is a must-have
  • Being a member of the Ryobi 40v lithium-ion battery powered line of tools – being able to use the same battery for many different tools is a game changer

What We Disliked

  • Not brushless – this model is the older brushed model that is tried and true, but you miss out on some of the power and speed from a brushless motor
  • A little heavy with the larger 4ah or 5ah 40V batteries
  • The smaller .080 line is not as aggressive as some of the other models, which means some tougher weeds might not get cut on the first pass of the trimmer line

EGO makes some great battery powered tools and the 15in 56 volt string trimmer is no exception. The trimmer has massive power with its 56 volt battery and impressive runtime the easily matches the power of gas powered weed eaters. The trimmer also has a larger diameter trimmer line that makes it more durable and can handle larger weeds and grass. It also has a cool line reloading feature where you press a button at the bottom of the head and it automatically spools the trimmer line.

  • Rapid reload head to quickly and easily load cutting line
  • 15 in. cutting swath
  • Dual-feed spiral-twist 0.095 in. line
  • Hi-efficiency brushless motor
  • Variable speed control
  • Weather-resistant construction
  • 2.5 Ah ARC lithium battery powers all EGO Power+ products

What We Liked

  • Power, Power, and more Power. Like all the EGO line of 56V tools, this thing has the powerful battery to get the job done and provide maximum power.
  • Thick .095 line, this is the same size line you will see on many gas trimmers and can clear the toughest weeds and dense grass with ease
  • Battery works with other EGO Power + products. Enough can’t be said about being able to use a battery in multiple tools

What We Disliked

  • Weight, with a larger battery you have extra weight to haul around which will tire you out after a long trimming session
  • Loading the trimmer line can sometimes be an issue
  • The included 2.5 Ah battery tends to run down quickly, with more power comes less battery life unfortunately

Makita is a long-time favorite of professional builders and contractors. This shows the quality of the 18 volt X2 LXT straight shaft trimmer. This trimmer comes with a powerful brushless motor, which overcomes the smaller voltage batteries used in this trimmer. The trimmer has a reverse rotation function which will help you get untangled if your trimmer string gets caught up in some extra tough weeds.

  • Makita-built outer rotor BL Brushless motor direct-drive system provides high power and increased torque
  • Variable speed trigger for power control
  • 3-Speed options
  • Equipped with bump and feed trimmer head loaded with 0. 080″ Twisted quiet Line
  • The reverse rotation function allows the operator to quickly clear the trimmer head of entangled grass and weeds

What We Liked

  • Multi-tool battery, the battery can be used with all 18v X2 powered tools, the one tested had 4 rechargeable batteries 18V batteries
  • Having multiple speeds is unique with the Makita trimmer. Being able to control power output for less intensive trimming (like around delicate landscaping) is a great to have feature.
  • The reverse feature is awesome, if you are like me when I have been trimming I have gotten tangled in taller woody weeds and had to manually unwind them from a trimmer head. Being able to reverse out of entanglement is very helpful

What We Disliked

  • 18v battery power is on the low end for this group of string trimmers. Most are 20v – 40v batteries
  • This is a higher-end trimmer with lots of features and it is relatively expensive model
  • Thinner .080 trimmer line will limit trimming of tall weeds

DeWalt is long time manufacturer of quality power tools used in the construction industry. The 20 Volt Max has a smaller 14in cutting width but has a variable high/low speed which will help you power through trimming jobs in your yard. One great plus is that the batteries for the trimmer will work in all 20V battery Max tools.

  • 14 in. Cutting Swath
  • Collapsible Design
  • 0.080 in. Line
  • Gear drive transmission design that powers through the overgrowth
  • Variable trigger with high/low speed control
  • Lightweight, ergonomic and balanced design
  • Part of the 20V MAX system of tools

What We Liked

  • 20 Volt lithium-ion battery works in all other DeWalt 20v max tools. There are literally a ton of DeWalt tools that use this same battery. Extra built in value if you buy this trimmer
  • The unique collapsible design makes for a compact trimmer that you can use on the go. This design would be perfect for those with smaller lawns/gardens and those that have limited trimming chores
  • High and low speeds help you apply the type of power you need for delicate or tougher trimming

What We Disliked

  • A running thread in this post but .080 line is on the smaller side and will limit your heavy duty trimming
  • While the collapsible design is unique for battery powered trimmers it also limits it to lighter duty trimming.
  • Smaller 20v batteries are on the low side for battery trimmers these days

Craftsman has been known to make quality power tools for many years and the V20 string trimmer is no exception to that rule. The trimmer has a powerful brushless motor ,variable speed control, and ergonomic handle for easier control. This trimmer is also light weight helping you get through those longer trimming sessions.

  • 13-Inch Cutting swath
  • 0.080″ Line
  • Patented gear drive design that powers through the over grown grass.
  • Variable trigger with Hi/lo speed control
  • High-efficiency Brushless motor
  • Lightweight and ergonomic design
  • Includes battery and charger

What We Liked

  • The V20 battery can be used in other Craftsman V20 lines of outdoor and garden tools
  • The “twist to edge” feature is a nice way to go from trimming to edging. This unique battery weed eater also has a telescoping shaft for reaching into hard to reach areas with ease.
  • Lightweight makes it easier to carry around and move from trimming task to trimming task.

What We Disliked

  • It was a little hard to replace the trimmer line once the included spool ran out.
  • The smaller battery doesn’t last long on high speed settings. But if you have to trim from longer than 20 minutes you might want to look at some of the higher battery capacity models
  • The Auto feed feature seems to waste a lot of trimmer line when it works.

Which battery powered string trimmer to choose?

Well, actually you can’t go wrong with any of these models. They can all handle your day to day trimming tasks with ease. I actually own the RYOBI 40 Volt Lithium-Ion Cordless Attachment Capable String Trimmerand I love it. I wouldn’t go back to using my gas powered trimmer. I am able to trim up around my house on a single battery and have never run out of battery power to finish the job.

Battery powered trimmers, in my opinion, are really the best choice when you need to get a new string trimmer, you get a powerful, quiet, nearly maintenance-free tool, at an affordable price, that starts every time. Any of the trimmers listed above would be a great choice for the best battery powered string trimmer of 2021. Get out there and clean up those edges.

1- EGO Power+ Powerload String Trimmer – EDITOR TOP PICK

The Ego Power+ weed eater has a sleek and modern look with silver and black housing which is durable and weather resistant. It features a 49-inch aluminum shaft and an adjustable design that makes it so much easier to use. This machine runs on a powerful and efficient motor which is complemented by a pump head for improved safety and reliability. This is a battery-operated and energy-efficient model which means it’s eco-friendly.

With a diameter of 0.095 inches, the dual-speed twist line is easy to maneuver and the 15-inch swath and cutting line combo add to the convenience. You’ll find that it’s incredibly easy to operate this device as well thanks to the variable speed setting options. Then you have the arc-lithium tech-powered 56 V lithium-ion battery which can last for up to 60 minutes on a full charge and the charger will power it up from empty to full within an hour.

There’s also a nine-pound weight trimmer and it’s backed by a five-year warranty.


  • Weather-resistant construction
  • Variable cutting speed
  • Long-lasting battery
  • Well-made and durable
  • Easy to use


  • It’s a bit challenging to assemble
  • Doesn’t come with the battery and charger

You won’t have to replace line as frequently thanks to the durable 0.095-inch string that it comes with, which you can boost even further with a bump. Not only that, but this weed eater weighs 12 pounds and doesn’t vibrate while moving, which means it’s less taxing to work with.


The DEWALT DCST920P1 is a convenient weed eater that actually offers the same power output as a gas-powered model, so you won’t feel any difference in performance when you make the switch. This brushless trimmer uses a proprietary battery system from DEWALT, so if you already have a tool from this brand then you won’t have to worry about buying extra batteries and you’re already familiar with its power output.

For an electric weed eater, the 13-inch clear range is pretty impressive and the battery will last according to the setting you use. On a low setting, this weed eater can last for up to an hour, whereas the high power setting will cut this time in half.

Unfortunately, this weed eater is not as well-made as it should be and it has some serious quality control issues. Of course, this isn’t always the case, but it has happened enough times to cause a lot of noise in the online review comments.

The good news is that DEWALT allows users to return and exchange malfunctioning units, which is too much of a hassle considering that the whole point of buying the machine in the first place was to enjoy the convenience it provides.

With all that said, the DEWALT 20V offers great value for money when it works.


  • Powered by the DEWALT 20V battery system
  • Has a 13-inch clear range
  • Long-lasting battery
  • Comes with low and high modes

Milwaukee has outdone themselves with this unit. This well-built weed eater is a dual-line unit that makes light work of mowing even the largest yard.

The powerful battery lasts for well over an hour at a time. Both the battery and the charger have compatibility with Milwaukee products, which means if you already own tools from this company then you’ll benefit from extra batteries and chargers. This dual-lined weed eater is backed by a durable motor.

All of these features come at the expense of a heavy weight. However, that’s a small price to pay considering the level of quality and performance you get. So, you have to lug it around your yard as you trim around the edges. At least, you know you’re getting a high-performance machine that’ll last for years to come.

The best part is that it features a telescoping shaft that allows you to customize its length to suit your height.

It comes with an integrated Worx 20V battery system which is similar to the DEWALT battery system but doesn’t work as well. Then you have the wire spools and poorly made trimming lines to worry about. This model lost a lot of points in our opinion due to those two simple factors. If they could only improve on that, the value and convenience offered by this model would increase immediately.

But, at the end of the day, you get what you pay for and as we said, it’s really good value for money overall.


  • It’s priced just right
  • Powered by the Worx 20V battery system
  • Has a telescoping handle
  • Works as a trimmer/edger
  • Adjustable spacer guard
  • Comes with batteries included


  • Annoying wire spools

This well-priced and lightweight weed eater from Worx is just what you need to maintain your home’s curb appeal without breaking the bank.


With impressive features like power drive transmission, cordless handling, and lithium battery power, the Black + Decker electric weed eater is one of the best battery powered weed eaters on the market for a reason. Considering the fact that this is a battery-powered model, this machine has very high power output.

But, what really sets this unit apart from the competition is that it offers optimized performance and efficient lawn mowing. The edger part of it is great for decks, garages, driveways. and sidewalks. Then there’s the automatic feed spool which is complemented by easy handling thanks to the lightweight design.

Another awesome feature of this unit is the power command controller which allows you to switch between different power levels and determine runtime. You can optimize your settings based on the type of grass you have and how much you want to preserve battery life.

6- Makita XRU09PT1 Cordless String Trimmer – BEST Rated

This lithium-ion powered string trimmer from Makita is a powerful machine that works quickly to efficiently eliminate weeds. It’s cordless and brushless, with a high torque that far exceeds most of its counterparts on the market.

You can adjust the speed trigger to optimize rotation reduction and there are two different speed options on the controller. This includes high and low torque variations that cater to your unique usage needs. The Makita XRU09PT1 can operate for up to 60 uninterrupted minutes which is enough to trim the average yard.

This trimmer is also powered by a 6500 RPM motor for improved performance and fast cutting. The ergonomic design and lightweight construction make it so much easier to carry this weed eater from one section of your yard to another without feeling like you’re lugging it around.

It’s small enough to fit into small spaces which makes for easier trimming and edging. Not only that, but the telescopic shaft featured on this weed eater means you can customize it to your height. But, you’ll need to purchase the battery and charger separately.


  • Comes with a long-lasting battery
  • Quickly finishes charging
  • Durable and well-made
  • Lightweight battery
  • 2-speed options
  • Versatile uses
  • Easy assembly


  • Poor customer service

7- Greenworks 12-Inch 40V Cordless String Trimmer BEST FOR BEGINNERS

The Greenworks 2101602 is powered by a 40V battery which like most of this company’s products, is interchangeable. Other features include a flexible speed trigger that improves power output whenever you come across a difficult spot in your hedge or a corner in your lawn.

Although interchangeable, the batteries have a short lifespan of up to 30 minutes or so. This is obviously not enough time to fully trim and edge a large yard. Some reviews show that this weed only lasts about 20 minutes before you need to recharge it again.

The batteries could definitely use some improvement and the company should definitely look into quality control. Users say the battery life is so poor that the trimmer often dies out quickly even when you don’t use it regularly.


  • Easy advance line
  • Comes with a spacer guard
  • Offers Greenworks replacement spool compatibility
  • Auto-feed line
  • Four-pronged pivoting head
  • Electric start
  • Variable speed trigger


  • Poor battery life

The best part is that this is a cordless machine and because of the brushless motor it doesn’t require costly repairs and maintenance. If you’re looking for something that’s easy to use, then the Earthwise LST02010 is the way to go.


  • Brushless motor
  • Flexible handle
  • 10-inch cutting width
  • Powered by a lithium-ion battery
  • Backed by a 2-year warranty
  • Adjustable telescopic pole


  • Doesn’t offer value for money

Apart from a few limitations, this unit comes with a number of great features, like durable construction, consistent run-time, powerful brushless motor, a fast charger, and a 20-volt 2. 0Ah lithium-ion battery.

9- Scotts Outdoor Power Tools LST01540S Cordless String Trimmer – BEST VALUE FOR MONEY

Its gear ratio is at 1:4:1 and delivers massive amounts of power which allows you to take down the most difficult aspects of your landscaping.

This is a well-built model that’s made from durable solid steel driveshaft. The Shindaiwa T3000 also comes with a line-decimating Speed-Feed 400 cutting head. You’ll experience the perfect cut, thanks to the optimally designed line twist.

Best Battery Trimmer For Lawns

Buyer’s Guide: How to Choose the Best Battery Powered Weed Eater

If the sheer variety of options available to you makes you feel confused or overwhelmed, here are a few factors you should consider to help narrow down your options and get you closer to a decision.

1)- Charging Time

To operate a cordless weed eater, you need a fully charged battery and this can take time. This means you can’t use it while charging.

That’s why people are looking for fast-charging units that will help you get the job done faster. For best results, look for a unit that takes 40 to 60 minutes to charge so it won’t take the whole day to mow your lawn.

2)- Battery Power

It used to be that gas-powered trimmers were considered better than battery operated models. But, the convenience and efficiency offered by cordless units are unmatched. Most modern models operate like the best gas weed eaters, except without the wallet-sucking and gas-guzzling performance.

Note that cordless units measure power according to volts or V for short. The most common trimmers are 20 and 40 volts and the one you pick depends on the condition and size of your yard.

3)- Battery Life

Lithium-ion batteries come highly recommended for their durable construction and long runtime. They offer quick charging times and if you have a small yard then a single charge is often enough to cover an entire lawn.

4)- Dual-Mode

Most cordless trimmers are optimized for flexibility and work as edgers as well. This means you can twist the head in order to trim the edges and other difficult to reach places. The dual-mode unit is for anyone who wants an immaculate finish and the LCC222 is a great example of this.

5)- One String vs Two Strings

The average garden only needs one line. Dual lines mean more cutting work, but they also make it easier to cut through dense shrubs, tough grasses, and thick weeds. The option most suitable to your yard will depend on its condition.

6)- Weight

Most cordless weed eaters weigh very little and you can trim your entire yard without feeling too tired or worn out before you’re even finished. It’s also much easier to use and allows you to cover large surface areas for a shorter amount of time.

7)- Warranty

While most people aren’t going to use or take advantage of the warranty, it’s still nice to have just in case something happens to the machine.

Most good manufacturers offer a warranty of one to three years, starting from the date of purchase. This warranty typically covers the cost or replacement or repair in case the machine breaks. You may even get a refund in certain situations, granted the damage meets the criteria for such.

It’s advisable to store your receipts and warranty documents in a safe place just in case you end up needing it in the long run. It might save you some money.

Types of Weed Eaters

Early weed eaters ran on gas but thanks to technological advancement we now have both cordless and corded versions. But, is a battery-operated model the best way to go for everyone?

There’s no definitive answer to this question but the following factors might help you answer it for yourself.

I- Gas Weed Eaters

Gas-powered weed eaters are lauded for their powerful performance and fast trimming ability. That’s because the powerful motor leads to powerful performance and all you have to do is pull a cord to activate the engine. However, the most attractive aspects of a gas eater include the fact that it can trim large swathes of grass and it’s fully portable.

Gas weed eaters are quite noisy and weighty, which means you might get tired lugging them around after a few hours. Over time, you might also find that it’s quite difficult to start your gas trimmer, especially if you don’t put a lot of effort into its maintenance. Plus, you have to deal with the fumes and air pollution it emits.

II- Cordless String Trimmers

Cordless string trimmers have come a long way since the first units were created, to the point that the latest models operate on a very high-performance level.

They’re no longer the fragile and weak machines they used to be and offer a runtime of up to 60 minutes. This is in stark contrast to the 10 to 15-minute runtime of past models.

Battery-powered weed eaters are also easy to use, highly portable and lightweight. They also work quietly so you won’t annoy your neighbors when trimming your lawn.

III- Corded Weed Eaters

Corded weed eaters are very popular because they operate on electricity and don’t emit any hazardous fumes. But they are lightweight and powerful enough to help you trim your lawn efficiently. Most models are flexible enough so that you can convert them into an edger if you like.

But, you can only use a corded weed eater for a limited distance because the cord can only go so far. The wire can also get tangled on shrubs and trees, thus taking longer to complete your work.

Battery Powered Weed Eater Advantages

There are many benefits to using a battery-powered weed eater. Read on for a few of them to help you figure out if it’s a suitable option for you.

If ease of use is important to you, then you should definitely consider battery-operated weed eaters, because they’re lightweight and highly portable. Most models weigh a few pounds which means you can work with them for a few hours without feeling worn out.

Doesn’t Make a Lot of Noise

Battery-operated weed eaters work noiselessly because they don’t contain a combustion engine.

You Can Easily Store It Anywhere You Want

Due to their lightweight and portable construction, battery-operated trimmers are super easy to store. This makes them ideal for users that only have limited storage space.

It’s More Affordable

Without the need for gas or oil, battery-weed eaters are cost-effective and energy-efficient. They won’t register a single tick on your monthly gas bill, and they will reduce your carbon footprint as well when compared to using corded or gas-powered models.

You Won’t Have a Hard Time Using It

To start a gas-powered trimmer, you have to go through a long and arduous process. On the other hand, battery-operated models are super easy to work with because all you have to do is press one button and it’ll start working instantly. They’re so easy to use that even a novice can get it started without any issues.

Type of Battery

Weed eaters typically use the following types of batteries:

I- Lithium-Ion

This type of battery is really popular because it’s not only powerful but it also offers decent energy storage. That’s why devices like laptops, phones, and power tools use lithium-ion batteries.

II- Lead Acid

Lead Acid batteries are commonly used in four-wheelers, ride-on mowers, tractors, card and other types of vehicles. This gives you an idea of their power and it helps that they’re resistant to most weather conditions and discharge, while offering higher cold-cranking amps.

III- Nickel Cadmium

Nickel Cadmium batteries are mostly utilized in household applications and include AA and AAA models. They don’t have a lot of storage space but they’re much cheaper than lithium-ion and Nickel Metal Hydride counterparts. They’re also resistant to extreme temperatures and you’ll need to discharge them at least once a month.

IV- Nickel Metal Hydride

These batteries offer less resistance which compromises their overall lifespan. They’re perfect for applications like high-lumen flashlights and flash photography.

How to Deal with Rechargeable Batteries?

The great thing about rechargeable batteries is that there are measures you can take to prolong their lifespan.

What You Should Do?

You Should Use the Battery Regularly

Using a battery for long periods of time obviously drains it faster and reduces its overall lifespan, but so does store it in a den for a whole season.

That’s why it’s recommended to use your weed eater at least once a week or at least turn it on so that it’s active. You should also avoid placing it in the charger while storing it for the winter.

Always Make Sure the Battery is Charged

Old wisdom told us that you have to wait until your battery was completely drained before you recharge it because that would prolong its lifespan. But, newer batteries actually require the opposite strategy.

They’ll last longer when you start charging the device at 70% or so. It’s worth noting that NiCd batteries feature a “memory effect” which tells you when you’re close or far from full capacity and you only need to discharge them once a month.

You should wait until the battery is fully recharged before you remove it from the charger. Your charger should come with an indicator light that tells you when it’s nearing completion.

Put Your Batteries in a Dry Place

While you probably shouldn’t store your battery in the refrigerator, you should look for a dry and cool area to store it in. Temperature extremes and humidity are not the best environments for any type of battery.

Make Sure You Store Them Properly

Most rechargeable batteries come encased in a cushioned bag or carrying case. However, it’s important to replace the plastic cap it comes with when it comes time to store the battery for the winter. That’s because a fresh cover will improve your ability to protect it from breakage and moisture damage.

Adjust the Settings

Be sure to familiarize yourself with the features and functions offered by your weed eater so you know which speed works best for longevity and performance.

High power settings are not recommended because they’re more likely to drain and damage the battery faster. But, if you have to use them just make sure to turn down the toque to extend your battery life.

What You Shouldn’t Do?

Don’t Drain the Battery

You probably shouldn’t deep drain your battery all the time but this might be what it takes to completely mow and trim your lawn. But, doing so will shorten the battery’s lifespan thanks to damaged poles. For best results, be sure to recharge your battery when you notice a lag in performance and deep drain your NiCd batteries at least once to prevent reduced capacity.

Don’t Overheat the Battery

You can easily overheat a battery by storing it in the wrong place. Avoid placing your battery in a place that’s prone to overheating as this may cause an explosion. If your battery gets too hot for you to touch it, try to move it to a cooler spot and only check it when it has cooled down.

Don’t Overcharge It

Look for one that comes with a charger that will automatically switch off when it’s done charging or just look out for the indicator light so that you can pull the charger out when it’s “full.”

Don’t Get It Wet

This one should be a no-brainer because water and electricity have never been friends. But, it’s worth mentioning that if your battery happens to get wet, take measures to dry it and remove all moisture.

Frequently Asked Questions

Why go with battery-powered weed eaters?

Older, gas-powered string trimmers can cause pollution and aren’t eco-friendly at all. They’re not cost-effective either and are quite noisy.

Rechargeable weed eaters, on the other hand, are very eco-friendly, cost-effective, and don’t make much noise.

How to remove the battery from the weed eater?

Every weed eater comes with an unlocking lever close to the battery. All you have to do is rotate or pull on this lever to remove the battery without directly touching it. It’s a very straightforward and uncomplicated process.

How to figure out the battery life?

Most weed eater batteries last for about 30 to 90 minutes. This depends entirely on the Ampere-hours (Ah) that can go from 1.3 to 5 Ah. This is known as autonomy and each manufacturer indicates this important detail on their website or product sheets.

But, it’s worth noting that poorly made models are unable to retain their autonomy and it will wane over time.

Is there any safety equipment required when using string trimmers?

A traditional battery powered weed eater is powerful enough to shred any obstacle in its way, from the smallest blade of grass to actual glass. That’s why you should always wear protective gear when using your unit. This includes sports shoes, gloves, safety glasses and long, tactical and durable pants.

A battery operated weed eater doesn’t make any noise, so you won’t have to wear any mufflers or noise-canceling headphones. But, you’ll need these for gas-powered weed eaters.

Is it possible to use other cutting heads?

You should follow the manufacturer’s recommendation when it comes to the way you use the cutting heads. You should avoid using differently sized blades and wires as that could incredibly damage the machine.
