Best Battery Lawn Mowers (2026) by Run Time per Charge

Last updated Researched from specs, manuals and owner reviews, not tested in person

Quick answer

The battery lawn mower with the longest rated run time here is the EGO LM2206SP: up to 70 minutes on its 10.0Ah battery, about half an acre per charge. The Greenworks 80V 25 inch covers up to 0.75 acre per charge, and the Honda HRX-BE about 0.37 acre with a second battery bay.

A battery lawn mower runs a brushless electric motor from a removable lithium-ion pack, so there is no oil, spark plug, pull cord or gas can. Run time is the question most buyers ask first, and the answer depends on three things: the battery's energy in watt-hours, how thick the grass is, and whether you use self-propel.

Our top pick is the EGO POWER+ LM2206SP 22 in. Aluminum Deck Self-Propelled Mower Kit at $1,299.00. It pairs the longest rated runtime in this list with a cast aluminum deck that carries a lifetime warranty. The Honda HRX-BE 21 in. Battery Self-Propelled Mower is the premium alternative for bagging quality and dealer service. If your lawn is larger than about three quarters of an acre, a battery walk-behind will need spare packs, and an electric riding mower is the better tool.

What battery lawn mower has the longest run time?

Among the walk-behinds in this list, the EGO POWER+ LM2206SP 22 in. Aluminum Deck Self-Propelled Mower Kit has the longest rated runtime at up to 70 minutes on a 56V 10.0Ah battery. By area, the Greenworks 80V 25 in. Self-Propelled Mower Kit has the largest rating, up to 0.75 acre on its 80V 4.0Ah battery, helped by a wider 25 inch deck. The EGO POWER+ LM2135SP 21 in. Select Cut Self-Propelled Mower Kit is rated for up to 60 minutes, and the EGO POWER+ LM2114 21 in. Push Mower Kit push mower for up to 55 minutes.

Runtime ratings are best-case figures for dry, regularly mowed grass. Owners commonly report shorter runs in thick spring growth, damp grass or when bagging, because the motor draws more power to keep blade speed up. Plan on 20 to 30 percent less than the rated figure for your first mow of the season.

Energy is estimated as labeled volts x amp-hours. Rated figures are from the manufacturer listings. Estimated areas assume about 0.43 acre per hour for a 21 to 22 inch mower at 3 mph with overlap and turns.

What do volts and amp-hours mean for battery mower runtime?

Amp-hours (Ah) measure how much charge a battery holds, and volts measure how hard it pushes that charge. Multiply them to get watt-hours (Wh), the true measure of stored energy. A 56V 10.0Ah pack holds about 560 Wh, and a 56V 5.0Ah pack about 280 Wh, so doubling amp-hours on the same platform roughly doubles runtime.

You cannot compare runtime across brands by amp-hours alone. An 80V 4.0Ah battery (320 Wh) holds less energy than a 56V 7.5Ah battery (420 Wh). Motor efficiency, deck airflow and blade design also matter, which is why EGO ships an extended-runtime lower blade with the EGO POWER+ LM2135SP 21 in. Select Cut Self-Propelled Mower Kit, and why the WORX WG760 40V 21 in. 3-in-1 Self-Propelled Mower uses IntelliCut sensors to lower blade speed in thin grass. If you already own tools on one platform, a bigger spare such as the EGO Power+ BA5600T 56V 10.0Ah Battery is the cheapest way to add runtime. Read choosing a battery tool platform before you commit.

Beginner Lowest total cost to a result that works, forgiving to own.

Beginner pick: simple battery push mowers

For small, flat lawns up to about a quarter acre, where self-propel adds cost without saving much effort.

Best for: Budget buyers with a small flat lawn

Intermediate The buy-once pick: best value per dollar for most yards.

Intermediate pick: self-propelled battery mowers for half an acre

The most popular class: 21 inch self-propelled mowers with enough runtime for a typical suburban lot.

Expert The performance ceiling: durability, capacity and pro features.

Expert pick: premium runtime, decks and dealer support

For larger lawns, owners who bag clippings, and buyers who plan to keep a mower for a decade.

Who should not buy this tier:

Skip this tier if your lawn is under a third of an acre and flat: a 21 inch EGO or Greenworks mower does the job for half the price. The eTimeMaster is also a poor fit for narrow side yards and gates under 36 inches, and its tool-only price rises once you add a battery. For lawns over 0.75 acre, look at a battery rider instead.

Assumes dry, regularly mowed grass. Swap in a charged spare pack instead of waiting for a recharge where the platform allows it.

Is a battery lawn mower as good as a gas mower?

For lawns up to about half an acre, yes. Premium battery mowers match or beat gas on cut quality and are far easier to start and store. EGO lists up to 11.1 ft-lb of cutting torque on the EGO POWER+ LM2206SP 22 in. Aluminum Deck Self-Propelled Mower Kit. Honda says the Honda HRX-BE 21 in. Battery Self-Propelled Mower matches the torque of its GCV gas engines. Gas still wins on long, uninterrupted runs, very tall or wet grass, and lawns over an acre where you would need several packs. The gas vs battery lawn mower comparison and EGO vs Greenworks lawn mower comparison cover the details.

Frequently asked questions

What is the best battery lawn mower for run time?

The EGO LM2206SP has the longest rated runtime in this list, up to 70 minutes on its included 56V 10.0Ah battery. By area, the Greenworks 80V 25 inch self-propelled mower is rated for up to 0.75 acre per charge. The Honda HRX-BE is rated for about 0.37 acre per 12Ah battery and has a second battery bay to double that.

How long does a battery lawn mower battery last per charge?

Most 21 to 22 inch battery lawn mowers run 40 to 70 minutes per charge in dry, regularly mowed grass. The EGO LM2114 is rated for up to 55 minutes, the EGO LM2135SP for up to 60 minutes and the EGO LM2206SP for up to 70 minutes. Thick grass, bagging and heavy self-propel use shorten runtime noticeably.

Does a higher Ah battery mean longer mowing time?

Yes, on the same voltage platform. Amp-hours measure capacity, so a 56V 10.0Ah battery runs about twice as long as a 56V 5.0Ah battery in the same mower. Across brands, compare watt-hours instead: multiply volts by amp-hours. An 80V 4.0Ah pack holds about 320 watt-hours, less than a 56V 7.5Ah pack at about 420 watt-hours.

How many years does a lawn mower battery last?

Lithium-ion mower batteries commonly last several seasons, often measured in hundreds of charge cycles, before capacity drops enough to notice. Heat, storing packs fully drained, and leaving them in a freezing shed all shorten life. Check the battery warranty terms on the product page: Greenworks, for example, lists a 4-year battery warranty on its 80V self-propelled mowers.

Can a battery mower cut half an acre?

Yes. The Greenworks 80V 21 inch and WORX WG760 are both rated for up to half an acre per charge, and the EGO LM2206SP's 70 minute rating covers about half an acre at a normal walking pace. The Greenworks 80V 25 inch mower is rated for 0.75 acre, which leaves a comfortable margin on a half-acre lawn.

Is it worth buying a second battery for a battery mower?

A second battery is worth it if your lawn is near or above your mower's rated area, or if you mow in one session and cannot wait for a recharge. The Honda HRX-BE has a second bay built for it. If you own other tools on the same platform, their batteries can often double as mower spares, which saves buying another pack.
