Simple operation

Just press a button to see how much charge you have left during use and when the battery will be fully charged afterwards.

Durable and robust
Greenworks batteries are not only powerful, but also particularly durable: thanks to the integrated deep discharge protection, the battery life is significantly extended, while there is no risk of a memory effect when charging. This means you can charge the battery at any time, regardless of the current charge level! In addition, the practical and robust design gives the 40V Li-Ion battery optimal protection from the outside.

Long enough to take a well-deserved break; short enough to quickly get back to gardening at full power. Never again be held back by too long charging times and enjoy efficient gardening instead - without tangled cables or dangerous trip hazards.
