The Milwaukee M12 XC 4.0 Ah Battery is built for users who rely on Milwaukee M12 cordless tools and instruments and need dependable power throughout the workday. This 12 volt lithium-ion battery delivers extended-capacity performance, offering 4 Ah of run time and 48 watt-hours of energy in a compact pack.
Designed with redlink circuitry and cell monitoring, the battery helps protect against overloads and cell-damaging discharge while supporting temperature regulation for longer operation and life expectancy. It is made to resist drainage when not in use and can recharge in 30 to 75 minutes with compatible Milwaukee M12 lithium-ion chargers sold separately. A fuel gauge on the tool indicates when it is time to recharge, and the flat-bottom base helps tools stand upright between tasks.
