The Milwaukee 48-11-2131C REDLITHIUM™ USB 3.0Ah Battery powers Milwaukee USB Rechargeable products with more runtime, quicker turnaround, and long service life. Delivering 20% more capacity than the first-generation REDLITHIUM USB battery (48-11-2130), this 3.0Ah cell extends time between swaps on headlamps, inspection lights, pen lights, lasers, and heated gear power bases that use Milwaukee’s USB-Rechargeable format. It’s rated for up to 1,000 recharges, helping reduce consumable cost and waste for crews that depend on compact lights and instruments every day. When paired with a Milwaukee USB Rechargeable product or the REDLITHIUM USB Portable Power Source & Charger (48-59-2012), it supports up to 3× faster charging, with a typical ~120-minute charge time. A durable PC-ABS housing stands up to drops and daily carry, while integrated electronics maintain performance over the life of the cell. Backed by a 2-year warranty, it’s a simple upgrade that keeps USB-Rechargeable tools ready.
