Battery Operated Weed Eater Buying Guide

It is a bit confusing for a new buyer to pick the best battery weed eater. In fact, it's overwhelming to select the right one among a lot of options. That's why I've added an extensive buyers' guide to choosing the perfect one.

Here you will get to know the important factors required when selecting the best battery weed eater.


Weight plays an important role while selecting the best battery weed eater for your lawn or garden. Some lawn experts introduce this factor as user-friendliness. The gardeners hold string trimmers for a long time while cutting grass; that's why weight does a matter.

I believe you already know I've used string trimmers several times in the above because weed eater, also called by this name.

Basically, gardeners choose weed eater for tough and awkward space. A lightweight tool isn't only easy to move but also durable. On the other hand, it reduces your tiredness too.

Despite the compatible, don't use other brand battery for your weed eater. It makes an uncomfortable situation in your hand while operating. However, all the manufacturers follow different weight measurements while designing the product. So, it could be a hassle if you use other batteries.

Machine Power

Usually, a battery-powered string trimmer comes with a 20-volt lithium-ion battery. But nowadays, a 40-volt battery is common as it lasts a long time and has huge advantages. I've reviewed both battery-powered weed eater above and mostly recommended a 40-volt one.

I've mentioned several times above; a 20-volt battery could be run for 20 to 35 minutes, but it depends on the brand. The Greenworks, Makita, DeWalt come with longer battery life. On the other hand, a 40-volt battery lasts at least 1 hour. You may check above; there are a few weed eater come with a 40-volt lithium-ion battery.

Trimmer Design

As you can see, I've compiled the best ergonomic designed weed eater in the above. And it is required to get the maximum output. However, manufacturers are doing an excellent job by making equal weight balance. Some machines come with a manufacturing defect in weight distribution; thus, you won't get the desired performance. By the way, a straight string trimmer is much preferable to a narrow one.


While running the machines, it vibrates. But there are only less vibration items in the above. But why does vibration matter? Well, it doesn't feel very pleasant when you hold it in your hand. You can't do the job while it is vibrating in particularly tough areas.

So, make wise decisions before miserably fail at work.

Trimming Area

While choosing a battery operated weed eater, it is a considerable factor to know the trimming area. If you own a large property, you need to select a longer battery life weed eater, whereas a small yard needs less battery power machine. So, it is wise to get the best one according to your yard.

Feeding System

There are four types of feed reloading enabled weed eaters available in the market, such as manual Feeding, bump head, auto-off feeds, and Automatic Feeding.

I preferred the automatic feeding line because it takes grass measurement and automatically feeds the lines. On the other hand, you need to feed the string manually, which is time-consuming.

This is one of the vital factors while choosing the weed eater. It makes a huge difference between high quality and garbage machines.

However, when it comes to the feeding line, make sure that it is thicker, not thinner. You won't get the sharp cutting through a thicker line.

Less Maintenance

By default, a battery-powered weed eater requires less maintenance, whereas gas-powered needs regular maintenance. Although, you have to keep them in a safe place after use. As it needs no effort, that's why it's trending to the gardeners.

Noise Free

It's not possible to get a noise-free weed eater; whether it's battery-powered or gas-powered. Usually, gas-powered makes a huge sound that causes ear loss. On the other hand, battery-powered weed eater makes less noise. Despite less sound, you need to get earing protection as well.

Cheaper Option

A battery-powered string trimmer is cheaper compared to a gas-powered. In fact, it requires additional gas or oil to run the gas trimmer. At the same time, a battery-operated trimmer requires charging before each use. By the way, I put the maximum low-price battery-powered weed eater on the above list.

Easy Access

Usually, electric and corded weed eater has huge disadvantages, whereas the battery string trimmer has easy access. It's annoying when you face a shortage of electric wire while cutting the grass on your lawn. For this reason, nowadays, a battery string trimmer is a must-have garden tool.
