Choosing the right cordless lawnmower comes down to three things:
The biggest reason to purchase a cordless electric mower is you won’t have to drag an extension cord around your yard. Cordless electric mowers use Lithium Ion or lead-acid batteries that produce various amounts of voltage.
The more volts the battery produces, the longer the motor will run and the more grass you can cut. Cordless batteries hold their charge longer than ever, and some can be recharged up to 500 times.
Push vs Self-Propelled
Cordless electric mowers give you a choice of a push style mower or a self-propelled mower. A push style cordless electric mower requires you to “power” the mower in forward and reverse.
A self-propelled cordless electric mower has powered rear wheels to drive the mower in a forward or reverse direction. As the operator, all you're doing is controlling the speed and direction that the mower is traveling in.
To Mulch, or Not To Mulch?
And what about those grass clippings? Cordless electric mowers give you the option of mulching the clippings until they are finely chopped, so they decompose and enrich the soil with nutrients.
You can also bag your clippings and keep your lawn looking neat and clean. Cordless electric mowers don’t always do a good job when you are bagging your clippings, but they are very efficient as mulching mowers.
