CEENR 5.0Ah Battery for Milwaukee M18 18V 48-11-1850 XC Replacement

The CEENR 5.0Ah battery is a drop-in replacement for Milwaukee M18 18V slide-pack batteries — it replaces Milwaukee 48-11-1815, 48-11-1820, 48-11-1828, 48-11-1840, 48-11-1850, 48-11-1860. It fits the same battery slot, needs no adapter or modification, and charges on the Milwaukee charger you already own.

At 5.0Ah it delivers far longer runtime than the smaller packs most tools ship with — ideal for contractors, remodelers and serious DIYers who run drills, impact drivers, saws and grinders through a full workday.

Inside are premium high-drain 18650 lithium-ion cells that hold voltage under load, managed by a 4-layer BMS with over-charge, over-discharge, over-current and short-circuit protection. Certified to the IEC 62133 lithium battery safety standard.

Tool fit: runs every Milwaukee M18 tool (M18 FUEL, ONE-KEY and FORCE LOGIC included) — 385 verified models, including the 2904-20 hammer drill, 2903-20 drill/driver, 2953-20 impact driver, 2767-20 and 2960-20 impact wrenches, 2834-20 circular saw, 2821-20 reciprocating saw, 2880-20 grinder, 2912-20 rotary hammer and 2744-20 nailer.
