Some things to consider when buying a cordless electric mower include battery life and whether you need features such as a mulching or a self-propelling design. Another factor to think about, as with any lawn mower, is what size of mower you need to maintain your yard.
Cordless electric mowers are powered by lead-acid or lithium-ion batteries that vary in the amount of time they stay charged, how long they must be recharged and the number of lifetime recharges per battery. Manufacturers often advertise their mowers based on the size of lawn they can cover on one charge. Some electric mowers come with a dual-battery system to extend mowing time.
As with gas-powered mowers, cordless electric models come in both push and self-propelled designs. The back wheels automatically move the mower backward or forward, while the operator controls the speed and direction. For homeowners who like to get a workout while they mow, push mowers may be a better option.
Most cordless electric mowers are marketed as environmentally friendly, so most of them have efficient mulchers. For homeowners who prefer to bag their clippings, the fine mulch many of them produce may be difficult to bag.
The width of the lawn mower determines how wide a swatch is cut during a single pass. Choosing an electric mower with a wider cutting deck allows operators to cut the yard in fewer passes.
