We use battery-powered equipment for a number of reasons, including:

Environmental benefits

Battery-powered equipment doesn't produce harmful fumes or emissions, which can help protect clean air and water, and combat climate change.

Lower maintenance

Battery-powered equipment doesn't require the regular maintenance of gas-powered equipment, such as oil changes, engine maintenance, and part replacements. 

Reduced noise

Battery-powered equipment is quieter to operate, which can be helpful for working at off times pf day or in noise-restricted areas.

Ease of use

Battery-powered equipment is easy to start and use, and doesn't require a pull cord.  It also doesn't require transporting fuel to fill up hand equipment.
