Weed Eaters: Battery Types

Generally, there are four types of batteries available with cordless weed eaters. Here, we have explained these battery types so that you can make an easy buying decision.

Lithium-Ion (Li-Ion)

Most of the devices you own, including smartphones, laptops, and much more, come with Li-ion batteries due to their lightweight and superior charge-storage capacity. Also, Li-ion batteries charge quickly and are safe to use.

Nickel Metal Hydride (NiMH)

Nickel metal hydride batteries last longer as compared to Li-ion batteries because these have powerful charge-storing cells. These batteries are most commonly used in flashlights and other high-power-consuming devices. You will find nickel metal hydride batteries in a few cordless weed wackers only.

Nickel Cadmium (NiCd)

Nickel-cadmium (NiCd) batteries are smaller as compared to NiMH and Li-ion batteries. The reason no manufacturer is using these batteries in their weed eater is due to their lower capacity. However, these batteries are relatively cheaper.

Lead Acid

Lead-acid batteries are the heaviest among all and these can add some extra weight to the weed eater. You will not find any weed eater with lead-acid batteries, as these require more maintenance and are costly.

Choose the Best Lightweight Battery-Powered Weed Eater: Guide

Choosing the best battery-powered weed eater can be daunting if you are buying it for the first time. Here are some factors you need to check before buying the best battery-operated weed wacker that delivers sheer performance and requires less maintenance.


The first thing you need to check is the weight. If the weed eater is heavy, then it would be difficult for you to maneuver it on your lawn. We have mentioned the weight of each weed eater in the comparison table, where you can easily check it for a rewarding buying decision.

Buying a lightweight battery-operated weed wacker will be a good decision, as you can use it for more time without getting exhausted.

Brushless Motor

Most of the battery-powered weed eaters listed in this article have brushless motors, so you can pick any one of these without thinking twice. The major benefit of choosing weed eaters with brushless motors is that they generate less heat and run smoothly.

With a weed eater with a brushless motor, you will get more runtime as the motor doesn’t get heated while you are eliminating the weeds from your lawn.


It’s quite evident that using a weed eater with immense vibrations is not a good deal. If the handle is vibrating vigorously, then you won’t be able to trim the weeds properly. Choosing a weed eater with fewer vibrations shouldn’t depend on your guesswork. There are some weed eaters available in this article that have fewer vibrations, so if you are elderly or cannot handle a weed eater with more vibrations, then you can go with these models.

Line Diameter

The line diameter is the total area available for trimming the weed. If you have a massive lawn, then go with weed eaters that have more line diameter, as you can speed up the job, which will save you time. On the other hand, if your lawn is small, then you can select any battery-powered weed eater with a small line diameter.

Cutting Swath

The cutting swath of the weed eater should be durable enough to withstand even the toughest of weeds. The good news is that most weed eaters have durable cutting swaths so you can easily make a choice of buying one.


Every battery-powered weed eater has a different run time because of the battery capacity. The choice is entirely up to you; if you have a big lawn, then go with a weed eater that has better run time. Also, it will save you from charging the battery multiple times.

Similarly, homeowners with small lawns can go with battery-powered weed eaters that have less runtime, as these are quite inexpensive as compared to weed eaters with better runtime.

Compatible Tools

There can be some circumstances when you have to add some extra tools to the weed eater to enhance its performance. And it is only possible with the weed eaters that allow you to add some compatible tools.

If you have multiple requirements to fulfill, then a battery-powered weed eater with compatible tools will be a good option.

Power of the Best Battery-Powered Weed Eater

Check the power each weed eater generates to evaluate its performance in the field. Every weed eater has different power because of the difference between the motor and the battery pack. Again, the choice is up to you and your requirements.

There are some extremely powerful weed eaters available on this list, like BLACK+DECKER LCC222 20V.

Guard Quality

Check the quality of the guard to make sure that you have a good time with the weed eater. A battery-powered weed eater with a poor-quality guard is of no use, as you have to replace the guard multiple times.
We have picked the only weed eaters that have durable guards so that you don’t have to struggle with buying one and replacing it every six months.


Generally, rechargeable weed eaters require less maintenance as compared to gas-powered ones. But there are still some devices that require you to pay more attention to maintenance. If you want to use a weed eater at certain times, then go with one that requires less maintenance so that you don’t have any problem starting it.


The last considerable factor is the price. There are multiple battery-powered weed eaters listed in this article for every budget. So you can make your choice accordingly. Considering your budget before buying a weed eater will help you save money and buy the right device for your needs.

FAQs: Picking the Best Lightweight Battery-Powered Weed Eater 

How do I use a battery-powered weed eater efficiently?

Using a weed eater is an easy task, and you can do it right away after starting the motor. However, there are some handy tips that make using this device even more effective.

Before you start trimming, the weed adjusts the height of the pole at your convenience. Also, we suggest you wear proper safety gear to protect yourself from the weed.

Once done with adjusting the height, select the ideal speed you need to trim the weed. Make sure to charge the battery fully so that you don’t have to stop the process to charge it again.

Always use the right type of trimmer line and use the weed eater in the right direction. After using the machine, clean it thoroughly before storing it so that no grass clippings can stick around the string.

Who makes the best battery-powered weed wacker?

It depends on certain factors like durability, after-sales services, and the price of the battery-powered weed wacker. In our opinion, Dewalt makes the best battery-powered weed wacker because of the quality of the device and its price.

How important is rpm when looking for the best battery-powered weed eater?

Looking for RPM is critically essential because a weed eater with a low RPM cannot trim the weed effectively.

However, most modern weed eaters have powerful motors with higher RPM, so you will not face any issues with them.

How does a battery-powered weed eater work?

The working of a battery-powered weed eater is simple, and you can compare it with your lawnmower in some terms. The motor supplies the power to the string, and that pulls out the weeds from the roots. Also, the battery supplies power to the moor so that it keeps working, and you can trim the weeds.

When should I consider getting a gas trimmer rather than a battery-powered one?

Modern battery-powered weed eaters are not inferior in terms of performance when compared to gas-powered weed eaters. But in some cases, you need a gas-powered weed eater because a battery-powered one will not be an option there.

If you want to cut the weed on commercial lands that are massive, then you need a gas-powered weed eater. The reason why you need a gas-powered machine is that the battery lasts for a limited time, but you can use the gas-powered commercial weed wacker continuously by filling in fresh gas.

But gas-powered weed eaters are noisy, and they produce a lot of pollution, which is not beneficial for nature.

How much power do I need in the best battery-powered weed eater?

You will be glad to know that most of the best battery-powered weed eaters come with adjustable power, and you can control the speed using the trigger. There is no fixed speed, as it depends on some parameters like the toughness of the weed and much more.

You can go with any of the weed eaters that come with a variable speed option to get different power from them.

Final Thoughts

Now that you know the importance of having a weed eater, you can select the best weed eater from this list. We only reviewed the weed eaters that come from a renowned brand and are in the top-selling category.
