MILWAUKEE, WI – Milwaukee Tool continues to lead in portable productivity, driving the next breakthrough in the M12™ System with the new M12™ REDLITHIUM™ HIGH OUTPUT™ CP2.5 & XC5.0 Battery Packs. M12™ REDLITHIUM™ HIGH OUTPUT™ batteries deliver 25% more power on high-demand tools while running substantially 25% cooler through heavy applications, allowing users to push the capabilities of their tools and maximize productivity.

“In 2018 Milwaukee® introduced M18™ REDLITHIUM™ HIGH OUTPUT™ batteries, elevating the performance of the entire M18™ platform,” said Product Manager, Zafir Farooque. "With the introduction of HIGH OUTPUT™ to the M12™ platform, the batteries are pushing the tool capabilities of existing and future M12™ tools.
