Kobalt 40V 5.0Ah replacement lithium battery for lawn mower, chainsaw and blower

40V 5.0Ah Replacement Battery for Kobalt Cordless Tools

A 40V 5.0Ah lithium replacement battery for Kobalt cordless lawn mowers, chainsaws and blowers. Same platform, same charger, noticeably longer runtime per charge than a worn-out original pack.

Why buyers choose this pack

5.0Ah of usable capacity — finish the lawn instead of parking the mower on the charger halfway through.
Drop-in fit — designed for the Kobalt 40V platform.
Consistent voltage under load — power stays steady when the blade loads up in thick grass.
No memory effect — top-up charging does no harm.
