Does this battery fit all Greenworks 60V tools?

Yes. Greenworks lists it as compatible with every tool in its 60V line, so it works with existing 60V mowers, trimmers, blowers and saws.

How long does it take to charge?

About 160 minutes with the standard charger. A faster charger shortens that, but the standard one is the slowest option.

Paired with the Greenworks Tools app, the battery reports real-time information on its charge and on the tools it powers.

It holds twice the charge, so it runs longer in high-draw tools, but it is heavier and takes longer to recharge.

Greenworks covers the battery with a 4-year warranty.

If you run a mower or chainsaw for long sessions, the extra runtime pays off. For light trimming, a smaller, lighter pack is easier to handle.
