Highest Rated Battery Powered String Trimmer

Last Updated on April 18, 2021 by the staff of TheAllElectricLawn

If you are searching for a string trimmer to trim weeds and bushes and keep your lawn in emerald condition, battery-operated string trimmers are an excellent option. Not only are they easy to operate but also cut fuel costs as they are solely powered by a battery. Another great thing about these units is that they produce less noise compared to gas string trimmers.

This type of string trimmer wasn’t always this popular. In fact, a few years back, battery-operated string trimmers were the least favorite among lawn enthusiasts. This is because the batteries of these units don’t have enough juice to last for even 20 minutes. This has changed now and modern battery operated string trimmers can work nonstop for as much as an hour. Below we have listed some of the highest-rated, battery-powered string trimmers. Pick a model from this list and you wouldn’t be disappointed by what this device has to offer.

Looking for the highest rated battery powered string trimmer

We took a look at 8 of the highest rated battery powered string trimmers available.  Each one is very popular and should meet the needs of any homeowner.  Take a look and see which one will work for you.

Greenworks 12-Inch 40V Cordless String Trimmer, 2.0 AH Battery Included 2101602


Powered by a 40V battery, the Greenworks Cordless String Trimmer can last for as much as 30 minutes before you need to plug it in to charge. As the name suggests, the cutting width of this unit is 12-inches, which isn’t too great but should be enough for small yards. It also features a variable speed trigger, which means that you can crank up the speed to cut through pesky weeds and power it down to save battery.

One downside to the Greenworks 40V Cordless String Trimmer is that it doesn’t support attachments. However, the advanced version of the unit – the 40V 14” Cordless String Trimmer – does support other yard tools so if you wish to use attachments with your trimmer, you can choose this one.  Battery and charger are included so it is quite reasonable given the features of the unit.

Worx WG163 GT 3.0 20V PowerShare 12″ Cordless String Trimmer & Edger


The Worx WG163 GT 3.0 is an inexpensive, yet powerful cordless string trimmer, which packs a 20V battery. This unit can be converted from weed whacker into an edger and vice versa within seconds, so it offers the benefits of both edging and trimming in a single unit. The cutting diameter of the unit is 12-inches, which is relatively small.

The Worx WG163 GT 3.0 comes with two 20V lithium-ion batteries but is powered by only one so you can use one battery while the other one charges. This way you won’t run out of power and can continuously whack the weeds.


BLACK+DECKER LSTE523 Li-On String Trimmer

The LSTE523 is another impressive tool that can convert from being a string trimmer to an edger within seconds. This model can be operated on two different power levels so you can balance performance with battery life. It also has a simplified string feeder, which lets you advance your 0.065-inch cutting line with the push of a button.

The LSTE523 is powered by a 20V lithium-ion battery which gives a run time of about 30 minutes, depending on the power level you choose. Its cutting width is 12-inches which might not be enough for some people.


DeWalt DCST920P1 Brushless Trimmer


The DeWalt DCST920P1 can make short work of pesky weeds and bushes, which rob the beauty of your yard. It is capable of all other 20V DeWalt tools, so you won’t be limited to using it as a string trimmer. The brushless 20V battery, used for powering the unit, increases its weight to 14 lbs, so it’s worth noting that you’ll be dealing with one of the heaviest string trimmers.

The DCST920P1 includes a charger and a 20V battery, which has enough juice to keep the trimmer running for an hour on a low setting. This unit features a cutting swath of 13 inches and a dual 0.080-inches line with bump feed. If you want a powerful stringer trimmer with long battery life to take care of your yard, the DeWalt DCST920P1 is worth considering.


Ryobi 40-Volt Lithium-Ion Cordless Attachment Capable String Trimmer 4.0 Ah Battery and Charger Included


The Ryobi Cordless Attachment Capable String Trimmer is powered by a 40V lithium-ion battery, which has enough juice to keep the unit running for about 30 minutes. This model has a variable speed trigger, which allows you to balance performance and battery life. The Ryobi String Trimmer also supports attachments so you can remove the trimmer head and replace it for a brush cutter, a pole saw, or other yard tools. It features a 0.080-inch twisted line and has a cutting width of 13 to 15 inches.

Included in the pack are a battery and a charger, which makes it a reasonable option for many lawn enthusiasts.


Ryobi ONE+ 18-Volt Lithium-Ion Cordless String Trimmer/Edger – 4.0 Ah Battery and Charger Included

The Ryobi ONE+ features a comfortable grip handle and only weighs 4.5 lbs, which makes it easy to use around the lawn. The cutting width of this unit is adjustable between 11 and 13 inches for ultimate cut control. This string trimmer is powered by an 18V battery, which gives a run time of up to 1-hour. The Ryobi ONE+ also sports a variable speed trigger, so you can choose between longer battery life and more power.

This unit comes with a 0.080-inch twisted single line, a 3-year limited warranty, and this includes a battery and a charger.


Ego 15 in. 56-Volt Lithium-ion Electric Cordless String Trimmer w/Rapid Reload Head with 2.5Ah Battery and Charger


The EGO Cordless String Trimmer packs a very powerful 56V lithium-ion battery, which has enough juice to keep the trimmer running for about 30 minutes. It runs a 0.095-inch trimmer line and has a cutting width of 15 inches.

The EGO Cordless String Trimmer also features variable speed control, giving you more command over its operation. This model weighs 10 lbs, which can make it somewhat difficult to use on large yards. The EGO cordless string trimmer includes a battery and a charger.


EGO 56-Volt Lithium-ion Cordless Electric 15 in. Powerload String Trimmer w/ Carbon Fiber Shaft (2.5Ah Battery & Charger)


With a 15-inch cutting swath and 0.095-inch cutting line, the EGO Powerload String makes taking care of the yard easier. It is powered by a 56V battery, which gives a run time of 30 minutes. This unit also gives you the freedom to change its speed, making it easier for you to tackle different obstacles in your lawn. The spinning direction of this trimmer is the opposite of most other models of its kind. But, this doesn’t affect its performance.

The EGO 56V Powerloand String Trimmer is backed by a 5-year limited warranty and comes with the battery and charger.

Which one is the best of the best?

Well, I guess that depends a lot on what you are looking for.  Though each of the models above is well received by users, the one you choose will greatly depend on the size of your yard or lawn, if you need to add or want to add attachments, and what type of battery life you are looking for.  However, if we had to choose one, I would go with the Ryobi 40-Volt Lithium-Ion Cordless Attachment Capable String Trimmer 4.0 Ah Battery and Charger Included.  It really is the best of both worlds, it has an impressive runtime, powerful motor, and ability to accept attachments.  That being said you really can’t go wrong with any highest rated battery powered string trimmer.
