The next best battery operated weed wacker is another WORX model. The WORX WG162 20V 12” Cordless String Trimmer/Edger is similar to the previously mentioned WORX model but it adds a few features for good measure. First, the shaft is adjustable for finding the right height fit. It also has wheels when in edging mode for straighter lines.

The WORX WG162 20V 12” Cordless String Trimmer/Edger is one of the best trimmer and edger two-in-ones on the list. It is easy to use, effective, and durable.

BLACK+DECKER LSTE523 Li-On String Trimmer

Landing at the fifth spot in the reviews is another BLACK+DECKER model. The BLACK+DECKER LSTE523 Li-On String Trimmer is a more powerful model than the previously reviewed BLACK+DECKER models.

This trimmer runs on a 20V battery and even has two speed control and a power drive transmission for increased trimming torque.

Consumers call this model a great trimmer for home use. The other big hit amongst consumers is its lightweight and ability to be handled by just about anyone.

DEWALT DCST925M1 String Trimmer, Yellow/Black

The next trimmer in review comes from the trusty tool brand DEWALT. The DEWALT DCST925M1 String Trimmer has the largest trimming diameter thus far on the list. With a 13″ trimming diameter and variable speed control, this DEWALT trimmer is meant to conquer the toughest of weed trimming tasks.

Consumers provide glowing reviews for this DEWALT trimmer. It is noted as being perfect for weekly and bi-weekly yard cleanup and is also noted as being simple to operate.


  • Gear drive transmission design allows for trimming of thick grass/weeds
  • Variable speed trigger allows for complete control

  • N/A


The DEWALT DCST925M1 String Trimmer is one of the strongest weed eaters in review here. With its variable speed trigger and gear drive transmission, there is not much this trimmer will not trim.

EGO Power+ ST1500-S 15-Inch 56-Volt Lithium-Ion Cordless Brushless String Trimmer with Split Shaft- Battery and Charger NOT Included

Next up in the battery operated weed eater reviews is the EGO Power+ ST1500-S. This model takes it a step further than the DEWALT model by sporting a 15″ trimming diameter, the largest on the list, period. It is also compatible with massively powerful 56V batteries.

Consumers claim that this EGO model is extremely powerful for a battery-powered tool. One particular consumer claims his trimmer works well over the entirety of a quarter acre plot without dying, although the battery is not included.


  • Compatible with large, powerful 56V batteries for extended use time
  • Huge, 15″ trimming diameter allows you to work quickly
  • Batteries and charger not included


The EGO Power+ ST1500-S is easily the most powerful trimmer in review. However, being that the trimmer does not come with the battery, the price of operation is high for this trimmer.

Makita XRU02Z 18V LXT Lithium-Ion Cordless String Trimmer, Tool Only, (Battery not included)

Landing at the eighth spot is the next best lithium battery weed wacker, the Makita XRU02Z. The Makita XRU02Z is designed with a string guard for safety and is designed to be lightweight and ergonomic, allowing for utilization by people of all strengths. The telescope shaft also allows you to customize the tool’s height to fit your needs.

Consumers are a bit mixed about this model from Makita. Some claim it is useful for simple yard trimming work but others note that it is weak and unable to cut some of the thicker weeds. One consumer even claims his trimmer just stops and smokes when it encounters larger weeds.


  • 7,800 RPM helps increase cutting speed, and thus efficiency
  • Adjustable shaft length for easy use by people of varying height
  • Batteries and charger not included


The Makita XRU02Z is a useful trimmer for small yards and occasional (few times a month) use. For larger yards and frequent trimming, this model will not suffice. The lack of included battery is also a bit of a deal breaker.


Earthwise CST00012 12-Inch 18-Volt Cordless Electric String Trimmer

The next model in a review is the Earthwise CST00012 battery powered weed wacker. The Earthwise CST00012 sports a large 12″ trimming diameter and a trim guard similar to other models. This model operates on an 18V, NiCad battery, rather than the common lithium-ion battery.

This model from Earthwise is popular among consumers. Some consumers note a long working life, with one particular consumer claiming that theirs has been running six years now! Additionally, the support team is helpful and noted as replacing dead or defective batteries for free.


  • Automatic line feed for ease of use
  • 3-position trimming angles allow for trimming in difficult corners, spaces
  • N/A


The adjustable nature of the Earthwise CST00012’s height and cutting angle is a huge selling point. This model is perfect for just about any yard and for use by just about anyone.

Ryobi 18V One Plus Line Trimmer Bare Unit

If we were to make a battery-powered weed eater comparison, this next model would most likely stand-alone. The Ryobi 18V One Plus Line Trimmer is a simple to use a trimmer from the very reputable Ryobi.

This model is compatible with batteries that are 18V ONE+ or lithium-ion. The model also converts between trimming and edging quite easily.

There is not a negative review to be found regarding this Ryobi weed eater. It is noted as being great for light yard work and even being relatively powerful for its battery size.


  • Easy switching between trimming and edging allows for use in multiple tasks easily
  • Fast RPM creates quicker trimming speeds and thus better trimming efficiency
  • N/A


The Ryobi 18V One Plus Line Trimmer is a great final trimming option from the list. It is the perfect small yard or light task trimmer. However, it does slack a bit in value with the battery not being included.

Factors to Consider When Buying Battery-Powered Weed Eaters

The following is a list of factors to consider when buying the best battery-powered weed eater:

Battery voltage:

The first factor to consider before buying a lightweight battery operated weed eater is the battery voltage itself. The battery voltage largely determines the strength of the weed wacker/eater and the length of run time itself. For instance, the models compatible with 56V batteries are much stronger than the 20V counterparts.

Not only are they stronger and more capable of handling thick weeds, the battery run time is longer, allowing you to cover more ground with one battery.

PerformanceAdjustability, convertibility:

The next factor to consider is the adjustability and convertibility of the trimmer’s features. If you are on the shorter side, buying a height-adjustable model is likely your best bet.

Additionally, trimmers that are able to be converted from trimmer to edger via a button are the best models for those looking for multi-functional trimming.

Trimming diameter:

A third factor to consider before buying a battery-powered weed eater is the trimming diameter. The trimming diameter will directly affect the amount of yard you can tackle on one battery charge.

While a 10″ trimming diameter is plenty viable, a 15″ diameter obviously tackles more lawn at once, and considerably more at that.

SignBattery included/not included:

The final factor to consider is whether or not the models you are considering come with the battery included. For instance, the strongest weed eater on the list, the EGO Power+ ST1500-S, is the best trimmer available but it is already very pricey without the battery included.

If you truly need a super-high powered trimmer then perhaps you do buy this model and a battery separately. But for most, the less strong models with batteries included should be plenty to get you by.

To get the best battery powered leaf blower is a good idea for your lawn maintenance. Those easy to carry and will make the cleaning of your garden much more easier.

Battery-Operated Weed Eaters FAQ

Who makes the best battery powered weed eater?

The best battery powered weed eater is likely the option from EGO. The EGO Power+ ST1500-S is the highest-powered weed eater in the reviews list, meaning that it is assumedly the best option.

However, not coming with a battery does hurt the value of this model. The best battery included model is likely the BLACK+DECKER LSTE523 Li-On String Trimmer with its two-speed control.

What is RPM regarding weed eaters?

The RPM of a weed eater means revolutions per minute. The higher the revolutions per minute, the higher the strength of the weed wacker because more revolutions per minute obviously mean faster string spinning, and thus more powerful trimming.

The models with the higher RPMs will always trim at a more effective rate than those with lower RPMs.

Do I need a convertible weed eater model?

The convertible weed eater models are perfect for those with muscular issues or weaknesses. The convertibility via the button on some models is more ideal for those who may struggle to hold a weed wacker at an alternate angle for edging versus trimming.

For older folks, convertible models are greatly beneficial to the joints and muscles. Also, some of the convertible models have wheels when in edging mode, which is helpful for getting perfectly straight edge lines.

What is automatic line feed?

An automatic feed line simply means that you do not have to bump the weed wacker to receive more trimming string. On standard weed whackers, you draw more string when it runs out by bumping the head of the wacker on the ground, which releases string by loosening the string holding mechanism.

Automatic line feed saves you from having to utilize this method and makes an operation that much more simple.


So in concluding, what is the best battery powered weed trimmer? Well, that depends on your situation, your yard, and your own capabilities.

However, the BLACK+DECKER LCC221 20V MAX Lithium String Trimmer/Edger Plus Sweeper Combo Kit is likely the best value package on the market.

But there are ten highly qualified options on the list that are all great for different reasons and in varying circumstances.

If you are looking for an absolute beast of a trimmer, look to the higher voltage battery options. If you simply need something to take care of small patches or areas of lawn, the lower voltage models will serve you just fine. So get prepared today and find the perfect model for your yard!
