About this battery

A high-performance replacement battery for Milwaukee M18 18V cordless tools, built and assembled in Australia by Marsen Energy.

Our 4Ah battery is built using genuine Molicel P42A 21700 lithium-ion cells, providing strong, dependable power in a compact 5-cell configuration. The 4Ah capacity offers a great balance between runtime, performance and battery size.

An integrated protection system helps protect the battery against overcharge, over-discharge and excessive temperature, while the built-in LED indicator makes it easy to check the remaining charge level.

Built in Australia. Powered by Molicel.
