Overview
This is a 4-pack of the Milwaukee 48-11-2425 M12 REDLITHIUM HIGH OUTPUT CP2.5 Battery Pack: four identical battery packs, model 48-11-2425, in a single listing.
The M12 REDLITHIUM HIGH OUTPUT CP2.5 delivers 25% more power and runs 25% cooler than other Milwaukee M12 REDLITHIUM CP battery packs, giving you the same power and runtime as an M12 REDLITHIUM XC battery in a lighter, more compact package. It delivers fade-free power and runs substantially cooler through demanding applications, and its compact, lightweight design helps in tight workspaces and reduces fatigue. Each pack is built for heavy-duty use and performs in climates below 0°F / -18°C.
The resistant housing provides increased protection against exposure to common oils, greases, and solvents found in transportation maintenance and manufacturing environments. REDLINK Intelligence provides optimized performance and overload protection through total system communication between tool, battery, and charger. Each pack is fully compatible with 125+ M12 solutions.
A good fit for M12 users running several tools at once, shops and fleet maintenance teams equipping multiple techs, or anyone who wants a deep bench of the same compact high-output battery.
