Milwaukee's M18 REDLITHIUM CP2.0 Battery Pack features a compact profile that supports easier handling without requiring users to move to a larger battery pack for every application. REDLITHIUM battery technology is engineered to provide reliable performance across demanding jobsite conditions, while the lithium-ion cell design eliminates the need for corded power when paired with compatible M18 equipment. The battery's 2.0Ah rating is well suited to applications where portability, tool balance, and convenient battery changes matter. As a replacement or additional battery, it also gives M18 users more flexibility for keeping multiple cordless tools ready for work.
