The Best Battery Powered Weed Eaters For Any Yard

There are many different weed eater models available on the market. Some are electric while others run on gas-powered engines which provide more power for heavy-duty jobs. Of course, some of the most efficient and effective weed eaters are those that are powered by batteries. For those who have a large yard, or for those who like to keep their lawn neat and tidy without worrying about another gas-powered engine, it’s important to invest in a high quality battery-powered weed eater.  

Ready to invest in one of these efficient tools so you can power through your toughest lawn care chores with ease? Here’s how to find the best one for your needs.

Did you know? The 5-Ah battery that comes with the DEWALT 20V MAX weed eater lasts long enough to trim over 2 acres on a single charge. We know this because we tested it!

Benefits of a Battery Powered Weed Eater

Battery-powered weed eaters (also called string trimmers or weed wackers) tend to be much quieter than their gas-powered counterparts. They are also slightly quieter than electric ones. That is a serious benefit for people tending to their lawns in crowded suburban areas – you won’t anger your neighbors with your early morning weedeating!

Since these machines lack combustible engines, that also means less maintenance. Though batteries can be somewhat expensive and they are considered wearable parts, you can often buy other tools from the same company that require the same battery – so you will only need to buy a limited number of batteries to help you save money.

Another benefit of using a battery-powered weed eater, especially compared to an electric one, is that these can often reach where other models cannot. Since there’s no cord to worry about, you can really go the distance! 

What To Look For in a Battery Powered Weed Eaters

We’ll give you some recommendations on the best battery-powered weed eaters below, but this list is far from exhaustive. So how do you know what to look for? When you’re shopping, consider these features in your search.


The bad news: these machines tend to be slightly more expensive upfront (due to the cost of most high quality batteries) than their counterparts. Of course, you’ll pay less in the long run, since you won’t have to worry about paying for gas, oil, or expensive maintenance and repairs.

Still, you’ll want to consider your budget as you shop. Bare tools (those without batteries) tend to be less expensive, while all-inclusive kits are more expensive yet still less pricey than piecemealing all required parts together from separate purchases. 

If you really want a good deal, consider buying a weed eater that will be compatible with other tools – that way, you can swap out batteries and potentially even parts to help you save money (and garage space!) in the long term.

Brushless Motor

This is a bonus feature that many battery-powered weed eaters have – and it’s definitely one worth noting. A brushless motor will give your machine a longer run time, more power, and a longer lifespan (with less maintenance) than a brushed motor. For anyone with experience using power tools, such as drills, you know how big of a performance improvement brushless motors have.

Line Diameter

If you only plan on trimming a small section of lawn, a smaller line, like a 0.080-inch line, will suit you just fine. However, for tougher areas that need to be trimmed (or for buyers who plan on using their weed eaters for professional use), you’ll want to choose a weed eater that has a 0.096-inch line capacity. This extra thickness will power through tougher weeds and grasses with ease.

Cutting Swath

Look for a battery-powered weed eater that has around 13 to 17 inches of cutting swath – the bigger the task you need to tackle, the wider that swath should be.

Vibration Control & Ergonomics

How comfortable will your weed eater be to use? The good news is that battery-powered machines tend to be far more comfortable to use than gas-powered ones. However, comfort still comes into play here. Look for a machine that offers vibration control so that it’s more comfortable to use as you work around your yard.


This is a key consideration to make when you are shopping for a battery-powered weed eater. Some string trimmers can only be operated for around twenty minutes before the battery needs to be recharged – a process that can easily take an hour and a half or more. That can be a serious pain! Look for those with longer runtimes, especially if you have a larger lawn that requires more hands-on time. 

This 5Ah battery can keep a weed eater running for quite awhile.
