Having read about the 10 bestbattery operated weed wacker, you might want to know how to choose the ultimate one. Here’s a list of things to look for in a cordless, battery operated weed eater.


Things to Look for in a Battery Operated Weed Wacker


Since you are choosing to switch to a battery-operated trimmer, this is what you should consider first. The best and most common type of battery used in a wacker is the Lithium-Ion one. That’s what you should choose too.


You do not want to leave half of your lawn shabby while the other half trimmed, do you? That is why you must make sure that the battery life is decent enough, i.e., at least 30 minutes. Additionally, if you get two batteries, that would mean prolonged and uninterrupted work.

Ampere Hours

It is the rate at which current flows through a battery. A higher AH would mean that the battery can exert higher power in less time and vice versa. That is, it can last longer. Alternatively, if low power is used, the same battery can work for a longer time.

Apart from these, you should look for a battery that can get charged quickly.

Weight and Design

The ease of use is an essential point to consider. You will need to carry your trimmer from one place to the other without dragging it, unlike the traditional ones. That is why you should look for the lightest option available (4-8 lbs)

Choose a trimmer that has an ergonomic design. You will need to use it for at least half to one hour, depending upon your lawn. A quality wacker will be lightweight and have a handle that does not strain your hand.


Your weed eater must have a power output of around 20 volts. You can opt for a higher one, but that will drain the battery faster. You will probably need to change the batteries more often or will need a spare one. That said, a trimmer with a higher power output will perform better.

If you need to cut thick grass that requires high power, you can opt for a wacker with 40V. However, it will be more expensive, and you will have to buy spare batteries for an uninterrupted performance.

Feed System

Every trimmer requires a replacement of line at some point in time. That said, you must know that the thicker the line, the longer it will last. Various trimmers have distinctive line reloading features.

  • The manual feed will require you to feed the line by yourself.
  • For the bump head, you must bump the head to the ground.
  • In auto-off, the line will feed as you switch off the machine.
  • The best system is automatic feeding. Here, the trimmer will automatically feed the line when you are running low on it.

You must surely go for the automatic feeding system as that is the most-efficient one.


Cordless tools are the energy-conserving, sustainable alternatives to the traditional ones. They have numerous advantages, such as ease of use and storage, minimal maintenance, lightweight, and low-priced. Additionally, they make lesser noise and zero-emissions, unlike the gas or electric-powered trimmers.

This guide gives you a list of the 10 best battery operated weed wacker. You must carefully weigh upon its features and then make your final decision. Checking its battery life, line reloading features, and ease of use are some of the few things to look into.

So, what’s the hold? Choose your favorite cordless weed eater and make the tedious lawn-mowing a quick and easy process!
