Milwaukee M12 REDLITHIUM CP2.0 Battery

Model number
48-11-2420

The Milwaukee 48-11-2420 M12 REDLITHIUM CP2.0 Battery is a compact 2.0Ah pack that gives M12 users a modest runtime increase without moving to a larger XC-style housing. It stays easy to carry on compact drills, impact drivers, ratchets, inspection tools, and lights where balance matters as much as runtime. Milwaukee lists 43-minute charging on a standard charger and 30-minute charging on rapid or super chargers, making it a practical everyday battery for rotation across several tools. It fits users who want a simple upgrade over 1.5Ah packs while preserving the smallest M12 form factor.
