Greenworks 40v/4Ah Lithium-Ion Battery | G40B4

This modern, no fumes, no fuss battery from zero-carbon-emissions brand, Greenworks, is a triumph of advanced technology and provides up to three-times more continuous running-time than a similar Ni-Cad model!

This 40v/4Ah lithium-ion battery maintains a constant flow of power throughout its cycle, and runs at full power until it empties, so there will be no running-down towards the end of a job.

You can switch-off and/or store this battery for just about as long as you like - whatever charge was in it when you put it away will still be there when you use it again.

Plus, the battery can be charged at any time during its power-cycle with no adverse memory effect - if you want just a couple of minutes of power for a quick job and not a full charge? You’ve got it. If you need to stop charging before the full cycle is done because you need to go out? No problem. That’s how flexible these batteries are.

Greenworks Lithium-Ion batteries have a longer life and will last up to 2000 cycles; and, in addition, they're very fast-charging and can take just two-hours to reach capacity.

The Greenworks G40B4 40v Battery will work with any of the machines in the Greenworks 40v cordless garden-tool range, so assuming you don’t need two tools working at the same time - or one charging and one working simultaneously - you only need one battery to run several items.

LED indicators are featured to give you power-level information; and there's a lengthy two-year warranty.
