Pros and Cons of Battery Powered Lawn Mowers Explained

As an Amazon Associate we earn from qualifying purchases. Details

Battery powered lawn mowers remove the cord, the fuel and most of the noise, but they trade that for limited runtime and battery cost. Whether that is a good deal depends on your lawn size, how much you can lift and store, and what is in the box. This guide sets out the main pros and cons, then uses six cordless mowers from different brands to show how those trade-offs look in real listings.

Quick answer

The pros: no extension cord, no gas, light bodies on small models, folding or upright storage, and batteries that can run other tools inside the same brand platform. The cons: runtime is finite, small decks need many passes, some listings are sold without a battery or charger, and claims differ a lot from model to model. Among the six below, the Greenworks 40V 16 inch is the most balanced starter kit, the RB 9 inch and the 9.9 pound small mower suit tiny lawns, the 16 inch 40V model has the widest deck but only a 10 minute listed runtime, and the Dewalt-compatible 14 inch mower is tool only.

Pros and cons of battery mowers, with the six examples

Greenworks 40V 16in Push Lawn Mower with 4.0Ah Battery and Charger

What it is: A push mower with a 15.67 inch deck, five heights from 1.25 to 3.75 inches, mulching and rear bagging. The maker says its battery fits over 75 tools in the same 40V system, and claims coverage up to one third of an acre on a full charge, depending on grass and technique.

Who it suits: A homeowner who wants a standard-size deck, a bag and a first battery in one box.

• Pros: complete kit, mid-size deck, 35 minute listed battery life, shared battery platform.
• Cons: at 37.5 pounds it is the heaviest here, and coverage is a maker claim.

Skip if: Lifting 37.5 pounds along your storage route is a problem, or your lawn takes longer than the listed runtime.

Litheli Cordless Lawn Mower, 13 inch, for 1,300 sq ft

What it is: A 13 inch deck mower weighing 24 pounds with a folding handle, an 8 gallon bag and a 4.0Ah battery with a charging cable. The maker claims mowing up to 1,300 square feet per charge, yet the same listing says 15 minutes of continuous operation.

Who it suits: A small, simple lawn with a tight shed or garage.

• Pros: folding handle, moderate weight, battery included.
• Cons: the 15 minute figure is short, and the height fields contradict each other (the spec field shows 13 inches, a bullet shows 1 to 2.5 inches).

Skip if: You need a long session or a verified cutting-height range.

RB 40V 9 inch Mini Cordless Lawn Mower for Small Yards

What it is: A 9 inch deck mini mower with a 40V 2Ah battery, a 6000RPM brushless motor, three cutting positions from 1.2 to 2 inches, pivoting front wheels, one-hand steering and upright storage. The listing says it suits lawns up to 540 square feet.

Who it suits: A tiny or cut-up lawn where turning and storage matter more than pass count.

• Pros: very maneuverable, stores upright.
• Cons: the 11.5 pound weight excludes the battery, and the maximum cut is only 2 inches.

Skip if: You want a wide deck or a cut above 2 inches. A listing note suggests it may be offered without a battery or charger, so check the box contents.

40V Electric Lawn Mower 16 inch, 2-in-1 Mulching, 2×4.0Ah

What it is: A 16 inch deck mower with mulching and bagging, a 10.6 gallon bag, five heights from 1.37 to 2.95 inches and a brushless motor stated up to 3400RPM. It comes with two 4.0Ah batteries and two chargers, but the product information states only up to 10 minutes of runtime with the dual-battery system.

Who it suits: A small area where you want the widest deck and a two-battery package.

• Pros: widest deck here, two batteries and two chargers.
• Cons: the 10 minute figure limits any larger or uninterrupted job.

Skip if: Your mowing route takes more than the stated 10 minutes.

Electric Small Lawn Mower with Auto Shut-Off Sensor, 9.9 lb

What it is: A 9 inch cordless mower weighing 9.9 pounds with an automatic shut-off sensor, three cutting heights (1.0, 1.6 and 2.2 inches), a 7500RPM brushless motor and a handle that adjusts from 54 to 59 inches. The bullets describe two 21V batteries and 45 minutes of operation.

Who it suits: Very small patches with tight access where carrying weight comes first.

• Pros: lightest mower here, long listed runtime for its size.
• Cons: narrow deck, low maximum height, and the spec field (9 inches) and a bullet (8.7 inches) disagree on width.

Skip if: You want fewer passes over open ground or a cut taller than 2.2 inches.

40V Cordless Lawn Mower Compatible with Dewalt 2x20V MAX Battery, 14 inch

What it is: A tool-only mower with a 14 inch deck, six heights from 0.98 to 3 inches, a 35L bag and a foldable design. It needs two compatible 20V batteries to make its stated 40V, and the compartment takes packs up to 4.0Ah. Battery and charger are not included.

Who it suits: Someone who already owns two compatible 20V packs and a charger.

• Pros: no duplicate battery cost for owners of that platform, tallest cut after the Greenworks, folds for storage.
• Cons: not usable out of the box, and the listing dimensions are clearly wrong for a mower, so do not use them to judge storage space.

Skip if: You are starting from scratch and want a complete package.

Buying checklist

• Estimate the area and route. Maker coverage claims such as 540 or 1,300 square feet are a rough screen, not a guarantee.
• Check the carry and storage path. A 9.9 pound mower and a 37.5 pound mower feel very different on steps.
• Match deck width to lawn shape. Wide decks cut fewer passes, narrow ones turn more easily.
• Decide on mulching or bagging, and confirm the listing supports it.
• Read the box contents. Only the Dewalt-compatible model is plainly tool only, and the RB listing needs a check.
• Do not assume batteries work across brands because the voltage looks alike.
• Disconnect or remove the battery before blade work and follow the maker manual.

FAQ

What are the main pros of a battery powered lawn mower?

No cord to drag, no gas to buy, and several models here are light or fold for storage. Some batteries also work with other tools in the same brand platform, as the Greenworks listing says for its 40V system.

What are the main cons?

Runtime is limited, from a stated 10 minutes on the 16 inch 2-in-1 model to 45 minutes on the 9.9 pound mower. Small decks need more passes, and a tool-only mower needs batteries and a charger you may not own.

Which of these mowers arrive with a battery?

The Greenworks, Litheli, 16 inch 2-in-1 and 9.9 pound mowers describe a battery in the package, and the RB mentions one in its title, so check that page. The 14 inch Dewalt-compatible mower is tool only.

Is a 9 inch mower practical?

It can work for a very small or cut-up lawn. The RB lists use up to 540 square feet and the small 9.9 pound mower lists 45 minutes of runtime. Both need many more passes than the 14 to 16 inch decks.

Can I share batteries between these brands?

Do not assume so. Each listing names its own platform, and the 14 inch mower is built for a specific 20V platform using two packs. Matching voltage numbers do not prove compatibility.

Closing note

A battery mower is a good fit when the runtime, deck width and box contents match a lawn you have measured. The Greenworks suits a standard small yard, the two 9 inch models suit tiny lawns, and the 16 inch 2-in-1 gives width but a short listed runtime. Confirm every figure on the current listing before you buy.
