Our M12 REDLITHIUM™ HIGH OUTPUT™ CP2.5 Battery Pack delivers 25% more power and runs 25% cooler than our other M12 REDLITHIUM™ CP battery packs. This increased performance of the lithium-ion battery gives you the same power and runtime of an M12 REDLITHIUM™ XC battery in a lighter and more compact package. The 12-volt battery pack delivers fade-free power and runs substantially cooler through demanding applications, allowing you to push your cordless power tools throughout a wide range of applications. Its compact, lightweight design allows you to work in tight workspaces and reduces fatigue. Each battery pack is durably built for heavy-duty use, runs cooler, and performs in climates below 0°F/-18°C. In addition, the M12 REDLITHIUM™ HIGH OUTPUT™ CP2.5 is built with a resistant housing, providing increased protection against exposure to common oils, greases, and solvents found in automotive and manufacturing environments. Our M12 REDLITHIUM™ HIGH OUTPUT™ CP2.5 is fully compatible with 125+ M12™ solutions.
