The Milwaukee M18 REDLITHIUM HIGH OUTPUT XC8.0 Starter Kit (48-59-1880) provides you with 50% more power and runs 50% cooler vs our other 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 all 175+ Milwaukee M18 solutions. Our M18 & M12 Multi-Voltage Charger accepts all of our M18 and M12 batteries, so you’ll always be prepared and productive, especially on jobs that require a mix of M12 and M18 Milwaukee cordless power tools. 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.
