The Milwaukee M18 REDLITHIUM XC5.0 Extended Capacity Battery Pack is a rechargeable 18V lithium-ion battery pack for Milwaukee M18 cordless tools. If you are trying to get longer runtime from your impact driver, drill, grinder, reciprocating saw, or circular saw without stepping up to a larger high-output pack, this is the standard 5.0 Ah battery a lot of pros keep in regular rotation.

Key Features

• More Work Per Charge: This Milwaukee battery is built to stretch runtime with a 5.0 Ah pack. It is a practical upgrade when your M18 tools are working hard and you do not want to stop for swaps as often.
• Onboard Fuel Gauge: The built-in charge indicator shows remaining runtime at a glance. That helps you plan battery changes before you are stuck on a ladder, in a crawlspace, or halfway through a cut.
• REDLINK Protection: REDLINK intelligence helps manage overloads, heat, and cell protection. That matters if you run high-demand cordless tools and want the pack to last, not just the charge.
