Love the GreenWorks range and find this battery perfect for using my chainsaw and weedeater. The battery last a decent amount of time, being adequate to get the job done.

Battery for blower

A good, light battery that charges quickly. It adds very little weight to the appliance and yet it seems to last for ages.

Excellent Backup Battery

about 1 year ago


Bought as a backup battery to the 4.0AH one. Don't have to worry about running out of power. When on discharges, put on the 2.0AH and carry on while the big one is recharging.
