Our M18™ REDLITHIUM™ HIGH OUTPUT™ XC8.0 Starter Kit provides you with 50% more power and runs 50% cooler vs standard M18™ REDLITHIUM™ XC battery packs. The optimized combination of smaller size and increased power of the 18-volt battery provides you with a great solution for the entire range of M18™ products. The lithium-ion battery delivers fade-free power and runs substantially cooler through heavy applications, allowing you to push your cordless power tools throughout a wide application range. The M18™ XC8.0 battery provides you with increased power in extreme-cold weather conditions (below 0F / -18C) and delivers more work per charge, driving corded replacement. The REDLITHIUM™ HIGH OUTPUT™ XC8.0 extended capacity battery is fully compatible with the M18 System. Our M18™ & M12™ Rapid Charger charges battery packs up to 40% faster, reducing your downtime and maximizing your productivity. The battery charger accepts all MILWAUKEE® M18™ and M12™ batteries, providing a charging upgrade for both systems. The battery charger communicates directly with your battery pack to monitor cell voltage, temperature and charge status to ensure a full charge. As an added level of communication, the charger indicates when the lithium-ion battery reaches an 80% charge, providing you with confidence that your battery can complete a substantial amount of work without waiting for a full charge.
