Testers checking mowed grass to find the best and worst battery-powered lawn mowers from CR's tests.
CR's testers evaluate evenness of cutting and several other factors to determine the best battery-powered lawn mowers.

Early versions of battery-powered mowers—often expensive and underpowered—could rarely cut a quarter-acre yard on a single charge.

That all changed a few years ago, when the Ego LM2002 became the first battery-powered model that performed well enough in our tests to make CR’s list of recommended mowers. Since then, other manufacturers have become serious about investing in lithium-ion battery technology, and the results speak for themselves.

“Today, the best battery-powered push mowers cut as well as comparable gas versions,” says David Trezza, who oversees CR’s lawn mower testing.

In our lawn mower ratings, we recommend several battery push mowers that do their job very capably. You can now score a top-tier mower for as little as $300.

These mowers are typically more expensive than gas mowers, due in large part to the cost of the lithium-ion battery that powers them. But that investment can pay off in other ways. You can use your mower’s battery to power other outdoor gear from the same brand, power tools such as string trimmers, leaf blowers, chainsaws, and more. 

How CR Tests Lawn Mowers and Tractors

To get you ratings and reviews of the latest models by early spring, our testers travel to Florida to conduct tests in late winter at grounds we maintain year-round. We plant 1,800 pounds of grass seed (predominantly annual rye, prized for its dense growth). We cut 500,000 square feet of grass in three modes—mulching, side-discharging, and bagging—a total of 3,000 pounds of clippings. We cover level turf, slopes, and in ditches to get a feel for each model. We also review the convenience features on every model we assess.

The Overall Score for each model in CR's mower ratings incorporates all that performance data, along with predicted reliability and owner satisfaction ratings from our latest member surveys. The surveys leverage data on more than 64,000 lawn mowers and tractors that members purchased between 2009 and 2019.

Battery Mowers That Don't Make the Cut

Less than a quarter of the battery push mowers in our ratings perform well enough for CR to recommend; among self-propelled battery models, half earn that distinction. Our testers have also identified a number of models that aren't worth your money. Here are a few of the battery-powered push mowers that struggled in our cutting tests.
