Milwaukee 48-11-2442 M12 Redlithium XC4.0 Battery 2-pack

Product Description

The MILWAUKEE 48-11-2442 is an M12 REDLITHIUM XC4.0 Extended Capacity Battery offered in a two-pack configuration. Each pack delivers 4.0 amp-hours (Ah) of runtime for M12 cordless tools. The pack is built with enhanced cell construction and onboard electronics that manage temperature and monitor individual cells during use. Performance is maintained in cold climates, including temperatures below 0 degrees F. Overload protection and discharge protection work together to reduce wear on both the battery cells and the connected tool. Licensed electrical and HVAC technicians, plumbers, and other trades professionals who rely on M12 platform tools will find this two-pack suited to full-day service work.

The 48-11-2442 two-pack is designed for use with Milwaukee M12 cordless tools across residential and light commercial service applications. Typical use cases include low-voltage wiring work, pipe cutting and pressing, HVAC service diagnostics, and general trade maintenance where compact cordless tools are preferred. The extended 4.0 Ah capacity makes each pack well suited to longer tasks between charges compared to standard M12 batteries.

Key Features

• 4.0 Ah extended capacity per pack for increased runtime over standard M12 batteries

• Discharge protection prevents cell damage during deep draw situations
