Is the 2.0 Ah battery worth it over the 4.0 Ah?

The 2.0 Ah is cheaper and lighter but runs about half as long as a 4.0 Ah pack. Buy it for trimmers and blowers; step up to 4.0 Ah or higher for mowers and chainsaws.

Which tools does this battery fit?

It fits Greenworks 40V tools, which the brand lists as 75+ models including trimmers, blowers, chainsaws and mowers. It does not fit 24V, 60V or 80V Greenworks tools.

Does it come with a charger?

No. This listing is the battery only, so you need a Greenworks 40V charger, which is often sold separately or in kits.

How long does a charge last?

Expect roughly 20 to 40 minutes in a string trimmer or blower and much less in a chainsaw or mower. Runtime depends on the tool and load.

Our take on the 40V 2.0 Ah High Power Battery

This is Greenworks' 2.0 Ah lithium-ion pack for its 40V outdoor power line, which covers more than 75 tools. It has a built-in battery management system for overheat, over-current, over-voltage, over-charge and short-circuit protection, plus an LED fuel gauge. The 2.0 Ah capacity is the small end of the 40V range, so it suits light tools and short jobs. At $86.95 at Amazon as of November 4, 2026, it is the best new price among 4 stores that list it.
