Milwaukee 48-11-1837D 2PC M18 18V Lithium-Ion REDLITHIUM High Output CP3.0 Batteries

Get XC-class performance in a compact, lighter pack. The Milwaukee 48-11-1837D M18™ REDLITHIUM™ HIGH OUTPUT™ CP3.0 batteries deliver 50% more power and run 50% cooler than standard M18 REDLITHIUM CP packs, giving small-footprint tools the punch and thermal headroom needed for tougher work. You’ll feel the difference on impact drivers, compact grinders, and saws—faster cuts and drives with less sag under load—while keeping weight down for overhead or tight-space tasks. REDLINK™ Intelligence manages output and overload protection, and the best-in-class pack construction is built for daily jobsite abuse. An onboard fuel gauge helps plan swaps before power drops. Fully compatible with the M18 system of cordless tools, these CP3.0s offer the runtime of an XC3.0 in a smaller, lighter housing.
