How long does the 8Ah battery run?

Honda positions the 8Ah pack for medium-sized lawns. Runtime depends on grass height, dampness and whether you use the self-propel drive, so tall, wet grass drains it faster.

Does it come with a battery and charger?

Yes. The mower ships with an 8Ah lithium-ion battery and a 2Ah charger, so it is ready to run out of the box.

How does it compare with Honda's gas HRX mowers?

It keeps the 21-inch HRX deck and walk-behind layout but swaps the gas engine for a battery. You lose refueling and engine maintenance, and gain quieter running, but runtime is limited by the pack rather than a fuel tank.

Can I use other Honda batteries in it?

It runs on Honda's battery system, so it takes Honda packs from that line. Third-party or other brands' batteries are not compatible.

Is a 21-inch deck the right size for my yard?

A 21-inch cut is a common residential size that trims mowing time on medium lawns. On small, obstacle-heavy yards a narrower mower is easier to maneuver.
