How does a batter weed eater work?

Before we discuss the best weed eaters, also known as string trimmers, it is important to get an idea on how they work in the first place. A weed eater is a lightweight tool that cut grass and weeds by using rapidly spinning microfilament string that becomes stiff enough through the rapid rotational motion. They can be gasoline, electricity, or battery powered.

As I mentioned earlier, a weed eater is a must-have tool for your lawn, driveway, and garden. It doesn't matter the grass height, a weed eater is a perfect fit for any job as it's a versatile tool. If you’re a gardener or someone who maintains a façade, may it be at home or at an office, then this tool will be your best friend in keeping a well-trimmed look.

You might be thinking a lawnmower is the all in one tool for your garden, but there are limitations to what it can’t do — it can't reach congested or tight areas and has limited mobility due to the need for access to a nearby power outlet. However, a weed eater can cover for all these limitations. On the contrary, a weed eater will not give you a more refined cut than a lawn mower. In summary, both tools are great at their specific purposes which is why it is very important to figure out the jobs you will be doing in order to make the right choice. If you’re already decided that a weed eater is the tool for you, then you’re in luck because this article will be the only guide you’ll ever need to find the best weed eater that suits your project and budget.

I did an in-depth review to come up with a comprehensive list of the best weed eaters in terms of value for your money. I don’t rate a product at their price alone but more importantly, I rate them by carefully analyzing its performance. More than fifty weed eaters were evaluated based on their performance, price, user-comfort, warranties, durability, battery, and many more. Below is my recommended top 10 best battery operated weed eaters. I hope that among these weed eaters, you'll find the right one for you.

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 in choosing the perfect weed eater suited to your needs.

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


Weight plays an important role when 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 is a vital consideration.

Usually, gardeners choose a battery weed eater for tough and tight spaces. A lightweight tool isn't only easy to move but also very versatile. Moreover, it reduces the strain during operation too.

Battery Capacity

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 longer and you charge less frequently.

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

Design and Build

As you can see, I've compiled the best ergonomically designed weed eaters above. This is very crucial in order to get the maximum output. What use is a long operating period if you feel very uncomfortable after a few minutes of usage? Thankfully, manufacturers are doing an excellent job by making equally balanced trimmers.


When using a battery weed eater, you can see that it vibrates during operation. But there above-mentioned items have way less vibrations than other models in the market. You might be wondering, why does vibration matter? Well, vibrations will bring a lot of discomfort if subjected to for long periods. You can't do the job well when it is vibrating like crazy during usage. Make sure to test-out the product before purchase to see if it vibrates too much to your preference.

Trimming Area

When choosing a battery operated weed eater, another considerable factor to know is the trimming area. If you own a large property, a 10” cutting diameter won’t be the perfect tool for you. Get a trimmer that has a trimming area best fit for the size of your needs.

Feeding System

There are four types of feeding systems for weed eaters available in the market, namely, manual feeding, bump head, auto-off feeds, and automatic feeding.

I prefer the automatic feeding line because it saves you so much time and effort. On the other hand, you need to feed the string manually in manual feed systems, which is very time-consuming.

This is one of the vital factors when choosing a weed eater. It spells the difference between high quality and garbage machines. A thinner line will be sharper but is also more brittle. It won’t hurt to try out different trimmer lines to find the size best suited to your needs.


By default, a battery-powered weed eater requires less maintenance, whereas gas-powered models needs regular maintenance. However, battery weed eaters are less durable so you have to keep them in a safe place after use. The convenience of a battery powered weed eater is the main reason why it's a trending tool to 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 lot of noise that can cause hearing damage over time. On the other hand, battery-powered weed eater makes less noise. Despite having less noise, you still need to get hearing protection.


A battery-powered string trimmer is cheaper compared to a gas-powered model. Furthermore, a gas-powered model requires fuel to run which is obviously an additional cost. In picking a battery weed eater, make sure to spend according to purpose. It is not advisable to get a $300 weed eater for a small garden.

Easy Access

Usually, an electric/corded weed eater has a lot of limitations in coverage area, whereas the battery string trimmer is very portable. 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.

Frequently Asked Questions

I've added some most frequently asked questions related to the weed eater. I hope it helps you make a better purchase.

How Does a Battery-Powered Weed Eater Work?

This eco-friendly cutting machine cuts grass with its head's feeding line. There are two lines, each length 9-12 inches on average. As mentioned, almost all weed eaters have a dual cutting system enabled. It means they have a trimmer and edger function. These cutting systems are interchangeable.

What is the Best Brand?

I've just reviewed renowned power tools brands. DeWalt and Makita are well known for manufacturing premium quality tools that are definitely worth it. On the other hand, Black+Decker specializes in producing gardening tools. You will never regret it if you buy from these brands.

What's the Service Life of a Weed Eater?

While it may be true that a battery weed eater needs minimal maintenance, you still need to keep it clean after every use. A good weed eater could be used for up to five years without facing any issues. If you encounter any problems, you may repair at your nearest service dealer.

Can I exchange the battery with another Brand?

This is not a good practice. It can cause damage to your weed eater. You run the risk of short-circuits which can ruin the motor. However, there are a lot of brands where you can change the battery with that of other tools.


As a tools expert, I always try to provide good value to my audience. That's why I've tested 20 weed eaters along with my team and came up with the list above. I've reviewed light and heavy-duty string trimmers for your yard and each have their own advantages and disadvantages. You have a lot of options with the list above and I’m quite sure that there is at least one that’s suited for your needs. These weed eaters are not only budget-friendly but also affordable.
