The MILWAUKEE® M18™ & M12™ Super Charger charges batteries up to 4X faster than standard Milwaukee chargers, massively reducing downtime and maximizing productivity. The charger accepts all M18™ & M12™ batteries, providing an upgrade for both M18™ & M12™ systems. M18™ REDLITHIUM™ HIGH OUTPUT™ HD12.0 fully charges in only 1 hour. HIGH OUTPUT™ batteries are optimized for use with Super Charger, each built with premium components for superior charging capability. Featuring REDLINK™ Intelligence, the dual battery charger communicates directly with each battery to monitor cell voltage, temperature and charge status to optimize the performance and extend the life of the pack. The Super Charger identifies the fastest charge rate for each M18™ or M12™ battery pack inserted, adjusting to charge each in the shortest amount of time possible. The MILWAUKEE® M18™ REDLITHIUM™ HIGH OUTPUT™ CP3.0 Battery Pack provides 50% more power and runs 50% cooler vs M18™ REDLITHIUM™ CP battery packs. This increased performance results in the same power and runtime of a M18™ REDLITHIUM™ XC battery in a lighter and more compact package. The 18-volt battery pack delivers fade-free power and runs substantially cooler through heavy applications, allowing trade professionals to push their cordless tools throughout a wide application range.
