Milwaukee M18 FB12 18v FORGE Li-ion Battery 12ah

The Milwaukee M18 FB12 is an 18V FORGE Li-ion battery pack designed to deliver maximum power, rapid charging, and extended runtime for demanding professional applications.

As part of Milwaukee's M18 system, the FB12 is compatible with over 290 tools, making it a highly practical investment for electricians, plumbers, carpenters, and general contractors who rely on a single battery platform across multiple tools. The REDLITHIUM FORGE technology sits at the top of Milwaukee's battery range, offering more power, faster charging, and longer cycle life than previous M18 battery generations.

The active cooling system helps reduce downtime by managing heat during intensive use, while the resistant housing offers increased protection against oils, solvents, and greases — ideal for busy workshops and challenging site conditions. Weighing 1.51kg, the FB12 balances high-capacity performance with a manageable form factor for extended use.

The enhanced onboard fuel gauge remains readable in direct sunlight, and with compatible fast chargers, the battery reaches 80% charge in as little as 35 minutes, keeping tradespeople on the tools for longer.
