Does this battery fit all M18 tools?

Yes. It works with any tool in the Milwaukee M18 system, including drills, saws and impact drivers.

How long does it take to charge?

About 1.5 hours with the included 48-59-1812 charger.

Is the 5.0 Ah pack worth it over a compact 2.0 Ah?

The 5.0 Ah gives longer runtime in high-draw tools but weighs more. Compact packs suit light drilling and tight spaces.

One M18 REDLITHIUM XC5.0 battery and one M18 charger.

Can the charger also charge M12 batteries?

Yes. The included charger is a multi-voltage M18 and M12 unit, so it tops up both battery lines.

Does the battery work in cold weather?

Milwaukee rates it for use down to -18°C/0°F, and its temperature management system protects the cells while charging and discharging.

About the Milwaukee M18 REDLITHIUM XC5.0 Starter Kit

This is a Milwaukee M18 starter kit: one 5.0 Ah REDLITHIUM XC battery plus the 48-59-1812 M18 charger. The XC5.0 packs Milwaukee's larger cell format, rated for up to 2.5X the runtime of standard lithium-ion packs, with an onboard fuel gauge and overload protection. It fits every M18 tool, so it works as a first battery or a spare for a growing kit. Against a single compact pack it trades weight for runtime, and against Milwaukee's larger High Output packs it gives up peak power in heavy-draw tools.

Best forFirst-time M18 tool buyers who need a battery and chargerOwners adding a spare 5.0 Ah packUsers of high-draw M18 tools like saws and grindersAnyone replacing a worn-out M18 battery
