How We Selected the Best Battery Operated Weed eaters

How We Selected The Best Battery Operated Weed TrimmersPin

Cordless weed eaters are versatile tools that keep your lawn tidy. Due to their design, they can reach even the smallest places.

Power is a crucial factor for any type of mechanical equipment. When we interviewed 10 longtime members of a local gardening group, they suggestedGreenWorksandDewaltare two of the brands that offer optimum power for a battery-powered string trimmer.

Based on online reviews, we’ve discovered thatBLACK+DECKERandWorxare homegrown favorites.

Of course, we researched the best budget models, which led us to includeRyobiandEGO Power+.

Afterward, we formulated some testing parameters to prove their features.

How We Tested: Factors to Consider and Buyer’s Guide

We put our selected cordless string trimmers to the test by seeing how they perform on both well-maintained and overgrown lawns.

As expected, it is more challenging to use battery-operated weed eaters on overgrown yards. However, they proved to be the most valuable in light trimming.

Afterward, we inspected each model for any signs of damage to ensure that everything held together well.

There are tasks that the rechargeable weed whacker should do:

Leveling GrassFrom what we have experienced from our tests, cordless models are best used in cutting the grass of small yards.
Smashing WeedsWhen you have an overgrown lawn, small shrubs and tough weeds could be vexing. We tested whether we need to recharge the battery of an electric weed eater more than once to finish the task.
EdgingHomeowners need trimmers to clean up grass found on sidewalks and driveways. Most rechargeable string trimmers have the capacity to do this, but those with a rolling section on the head and a straight shaft will make it easier.

Note that most battery-powered weed wacker in this article are suitable for light trimming and edging. This is why we’ve compiled the best electric weed eater whackers for homeowners.

To determine if they can support your leveling, smashing, and edging needs, here are the factors you need to consider before buying a battery weed eater:

Lawn Size and Type

The best battery-powered string trimmers reviewed in this article use lithium-ion batteries.

However, certain factors affect their capabilities. For example, if you are trimming overgrown grass or edging on hard surfaces, you might need to exert more power. As a result, you drain the battery faster.

Cutting Swath

How We Tested Factors To Consider And Buyer’s GuidePin

How wide your battery-powered string trimmer can cut is essential. The larger lawn you have, the bigger the cutting swath you’ll require.

Yet, smaller swaths are beneficial when you have fencing or rocks.

Trimmer Line Size

Light Duty0.065 to 0.080 inchesPerfect for light weeding and cutting.
Medium Duty0.085 to 0.105 inchesAdvisable for lawns with denser weeds.
Heavy Duty0.110 inches and upwardsApplicable for commercial lawns.

Shaft Type

Straight Shaft – This is recommendable when you need to get under objects. The best rechargeable weed eater should allow you to cut under objects conveniently.

Curved Shaft – If you want a weed eater that can get around hard features or fences, a curved shaft is absolutely a must-have. A curved shaft enables you to move around swiftly and get close to fences without snapping off trimming lines.

Split Shaft – This is good when you want to attach accessories like leaf blowers or hedge trimmers.

Speed Trigger

Having an on and off switch suffices some homeowners, yet the best battery-powered string trimmer must have variable-speed triggers.

When you turn the equipment on, it will normally operate at the highest motor speed, then draining the battery rapidly.

Thus, variable speed triggers extend battery life because you will use the cordless weed eater lightly in small cutting jobs and harder on denser patches of weed. 

Number of Strings

The best cordless weed whackers traditionally have either one or two cutting strings.

Only use dual-strings for heavy-duty work to make cutting tougher weeds stress-free. Alternatively, if you have dense weeds to take care of, you should look into a walk-behind string trimmer or even a gas-powered 4-cycle trimmer. These two alternatives can handle the heavier weeds better. 

Automatic stringsYour electric weed eater will continuously release the line if it has an automatic string.
Individual loading stringsThis type of string lets you quickly put or replace short lengths of trimmer line into the head and replace them.
Bump loading stringsIt’s about simply ‘bumping’ the head of the rechargeable weed whacker into the ground to release more line.

Trimmer Head

Fixed HeadTired of winding the line onto the head of your battery-operated string trimmer? A fixed head is your savior. It normally lasts longer than other trimmer head types.
Automatic FeedLooking for minimal feeding work, yet maximum outcomes? An auto-feed cordless model is the right one for you. This is the usual trimmer head for most battery-powered units.
Bump FeedBut if you are a fan of control and reliability, then a bump feed will not fail you. This is because of the lengths of line fed around the spool of your cordless weed eater.


The design of your battery-powered string trimmer is another determining factor. You’ll want to have a tool that has a good handle and even anti-vibration features.

Dual Mode

Simply put, you are getting the best of both worlds when you have a trimmer and edger in one piece of equipment.

There are rechargeable weed eaters that can be converted into edgers by rotating the head. This is beneficial because it means getting two pieces of equipment in a single tool.


Most manufacturers of the best battery-operated weed whackers offer at least a 1-year warranty. Some even have a money-back guarantee and service warranty.


The best battery-operated string trimmer can be costly but for justifiable reasons. Some models are budget-friendly yet will not sacrifice the necessary features.

Frequently Asked Questions About the Best Battery Powered Weed Eaters

Why Should I Choose Battery Operated Models? 

Older units of string trimmers are powered by gasoline, which isn’t environmentally friendly and cost-effective. Not only will they keep you spending cash on gas, but they will also irritate you because of the noise.

On the other hand, rechargeable weed whackers will only require you to recharge batteries. They also produce little to no noise.

How Beneficial Are Cordless Weed Whackers?

Woman Using Cordless String TrimmerPin

Seven things: powerful, practicality, portability, lightweight, convenient, ergonomic, and good for the environment.

Basically, rechargeable weed trimmers equate to no gasoline and power cords. Since there are no cords or gas to worry about, they are quiet, easy to use, give a better reach, and non-polluting.

You can carry the tool with ease since it allows you to comfortably maneuver it.

Manufacturers ensure battery-operated weed eaters can finish a trimming routine. This is why they are usually powered by 20V to 40V lithium-ion batteries, ensuring long battery life.

If you are not a fan of rewinding lawn trimmers, then better get a battery-powered weed eater. Another alternative is a reel mower – this piece of equipment should go through weeds very easily.  

Rechargeable Weed Whackers Are Without Flaws, But They Make Up For It

Some batteries do not last for long and must be recharged before finishing your trimming job.

The six battery-powered models we’ve reviewed all have the capacity to operate for at least 30 minutes, some even longer.

A 30-minute capacity should suffice if you need light trimming and edging.

Otherwise, you might need to buy extra batteries or recharge batteries from time to time.

There’s no need to delay your maintenance jobs when you have a high-performing tool.

Battery Powered Weed Eaters Do’s And Don’ts

Use safety glasses or tight-fitting goggles to protect your face from flinging debris.Force your rechargeable weed whacker through a thick patch of grass. Instead, slice into it slowly and work it down.
Wear long-sleeved shirts, long pants, and work boots.Use the tool when your lawn is wet.
Protect your hands using work gloves. Also, cover your ears with earmuffs if you are sensitive to the noise.Swing the equipment back and forth. It is ideal for making slow passes for absolute cutting efficiency and control.
Remove the battery of your tool before making adjustments to the trimmer or changing the cutting line.Use the equipment to cut vines, twigs, and thick stalks.
Keep an extra spool of cutting line just in case your trimmer runs out of line.Cut too close to the ground to avoid scalping the lawn.
Trim far away from humans or pets. Make sure no one is within a hitting range.Operate the battery-powered system without reading the user’s manual.

Why Does the Trimmer Line Break?

This is usually caused by line crowding, especially when you hold your weed eater too close to hard objects such as fencing or rocks. To solve this, always keep the line at full extension.

Maintaining Rechargeable Weed eaters.

Most units can’t be cleaned using water because of the battery. Usually, a unit’s manual guide explains how to best clean it.

As a general rule, use a brush to remove clinging grass from your equipment.

When you need to change parts, turn the equipment off and wait until all moving parts halt.

When it comes to changing the trimmer line, it would depend on whether your battery-operated weed eater is single- or dual-line.

It’s wise to check the user’s manual first. Normally, this process would require a pre-wound spool, precut pieces of line, or winding the line yourself. 

Clean the cutting shield and around the trimmer head. This is also the right time to check for any damage.

Should you need to replace some damaged parts, use only approved replacement parts. Seek professional help whenever necessary.

Let the equipment cool before storage. Keep it in a dry, well-ventilated place.
