Cross-Platform Compatibility

REDLITHIUM vs REDLITHIUM FORGE
Milwaukee sells several 6.0 Ah M18 packs: the 48-11-1860 (REDLITHIUM XC6.0), the 48-11-1865 (HIGH OUTPUT XC6.0; the 48-11-1862 is a two-pack of it) and the 48-11-1861 (FORGE XC6.0). All are M18 batteries, and Milwaukee says all M18 batteries are compatible with M18 tools. On Milwaukee’s US chart the FORGE XC6.0 charges fastest of these listed (25 minutes on a super charger, against 35 for the HIGH OUTPUT XC6.0).
Replacement Battery Options
Genuine Milwaukee 48-11-1860 replacements are available from Milwaukee authorised dealers. Compatible third-party M18 6.0 Ah batteries are available from several brands — verify that the listing confirms compatibility with your specific M18 FUEL tools, as high-draw tools can be more sensitive to non-genuine battery performance.
Specifications reflect standard production variants. Always verify compatibility with your specific tool model before purchase. For the most current product information, visit the manufacturer’s official website.
