Greenworks 80V 4.0Ah lithium battery for lawn mower, chainsaw and blower

80V 4.0Ah Replacement Battery for Greenworks GBA80400

This 80V 4.0Ah lithium replacement battery is built as a direct-fit pack for Greenworks 80V outdoor power equipment, including lawn mowers, chainsaws and blowers. When the original GBA80400 pack starts fading mid-season, this is the drop-in replacement that puts the tool back to work.

What you get

Direct fit for the Greenworks 80V platform — no adapters, no rewiring.
Full 4.0Ah capacity — enough runtime for a normal mowing or clearing session.
Stable output under load — the pack holds voltage when the blade meets tall grass or the chain bites into wet timber.
No memory effect — partial charging between jobs will not shorten pack life.
Low self-discharge — still ready after months in the shed.
