The Electric Lawnmower using a battery is a great invention. With battery technologies improved so much over the last 10 years, I can easily cover my whole lawn in about one hour with power to spare in the lithium cells and expect batteries to last 10 years.

Having used several I would say "buy a good one", which set me back about $500. At half that price the power is less and the battery depletes in about 30 minutes. Larger models are self-propelled, capable of slogging through that high grass and spongy turf for over an hour.

Compare accessories like string trimmer, edger, and blower from the same manufacturer. These will share the battery with all devices.

WARNING: Batteries are not interchangeable between manufacturers

So I have found both low and high end models work well if you match them for the job at hand. A small model in tall wet grass will have to be cleaned underneath with a hose often or it will stall. However a small one is good for going in and out of ditches or hills. A larger one will clear tall grass out the chute better, and provide extra torque required to keep the blade spinning up to speed.

Also my 4 Amp-hour (4Ah) battery lasts longer than a standard 2Ah. Lately I have even seen 6Ah batteries (40-volt) in the stores.

Finally, the best part of an electric cordless lawnmower is maintenance; no gas, oil, filter, spark plug or carburetor. And it starts first time, every time without taking that little red jug to the gas station or pulling on a rope. Just plug a charger into the wall and top off your battery after each mow.
