Does this battery fit all Greenworks 60V tools?

Yes. It is part of the Greenworks 60V family and works with the 60V mowers, trimmers, blowers, chainsaws and other 60V tools. It does not fit the 24V or 40V lines.

Is a charger included?

No. This is a bare battery. You need a Greenworks 60V charger, which is sold separately or comes with tool kits.

How does the 5 Ah compare with the 2 Ah and 8 Ah packs?

The 5 Ah sits in the middle: it runs longer than the 2 Ah and 2.5 Ah packs but weighs more, and it is lighter and shorter-running than the 8 Ah pack.

How long does it take to charge?

Charge time depends on the charger. A fast Greenworks 60V charger refills it quicker than the basic chargers that come in starter kits.

Can I leave it on the charger or in storage?

Lithium-ion packs hold charge well. Store it cool and dry, and top it up before long storage rather than leaving it fully drained.

Is it worth buying as a spare?

If you already own 60V tools and run out of charge mid-job, a second 5 Ah pack keeps you working while the first recharges. It is less useful if you only have small jobs.
