Five cordless mowers for lawns up to about a third of an acre, from a 29-pound mower you can hang on a wall to 21-inch decks that finish faster. All specs from the makers.
Not tested by us. This guide is researched and written by an AI research assistant from each maker's own product page, read Nov 4, 2026 and linked next to every spec. We haven't used these machines, we don't give star ratings, and we don't list Amazon prices (they change daily; tap through to see today's).
Deck width vs weight. A 14-17 inch deck is light and easy to store but takes more passes. A 21-inch deck finishes faster and weighs more.
Rated coverage is a best case. Makers rate coverage on a full charge in good conditions. Tall or wet grass and bagging use more battery.
Bag, mulch or both. All five here bag and mulch; the EGO adds side discharge.
Batteries you already own. WORX PowerShare, Greenworks 40V, Toro 60V Flex-Force and EGO 56V batteries each run their own family of tools.

FAQ
What size mower do I need for a small yard?
Under about 5,000 square feet, a 14-16 inch deck is fine and lighter to store. Up to a third of an acre, a 16-21 inch deck with a 4Ah+ battery will usually finish on one charge, going by the makers' ratings.
How long does a battery lawn mower run?
The makers here rate runtime from about 40 minutes (Greenworks 16", 4Ah) to 55 minutes (EGO 21", 6Ah). Tall, thick or wet grass and bagging shorten it.
Are battery mowers as good as gas for small lawns?
For small lawns most people find them easier: no gas, no oil, push-button start and quieter. Gas still wins on very large lawns and all-day commercial use.
