Milwaukee M18 REDLITHIUM 3 Ah and 6 Ah Lithium-Ion High Output Battery Kit 2 pc

M18 Redlithium high output batteries provide you with 50% more power and run 50% cooler vs standard M18 Redlithium battery packs. The optimized combination of smaller size and increased power of these 18-volt batteries provide you with a great solution for the entire range of M18 products. The M18 Redlithium high output XC8.0 delivers fade-free power, long runtime, and runs substantially cooler through heavy applications. It provides you with increased power in extreme-cold weather conditions (below 0F / -18C) and delivers more work per charge, driving corded replacement. The M18 Redlithium high output CP3.0 delivers the same power as M18 Redlithium XC batteries in a lighter and more compact package. Both batteries are fully compatible with all M18 tools.
