Overview
The Milwaukee 48-59-1865H M18 REDLITHIUM HIGH OUTPUT XC6.0 Battery Starter Kit pairs one 6.0Ah HIGH OUTPUT battery with the M18 and M12 Multi-Voltage Charger. This is a cordless tool battery and charger kit designed to add runtime and power to any Milwaukee M18 tool. Model Number: 48-59-1865H.
The HIGH OUTPUT XC6.0 pack (48-11-1865) is the step up from a standard M18 XC battery. Milwaukee rates HIGH OUTPUT packs at up to 50% more power and cooler running than standard M18 REDLITHIUM batteries, which shows up on high-draw tools like circular saws, grinders, and large impact wrenches where a standard pack bogs down or trips its protection.
A built-in fuel gauge on the battery shows remaining charge at a glance, and the pack fits the full M18 lineup. That makes this kit a straightforward way to upgrade a bare tool or add a second high-power pack to an existing setup.
The included 48-59-1812 M18 and M12 Multi-Voltage Charger has one M18 port and one M12 port. If you run both Milwaukee platforms, one charger on the bench or in the truck handles both batteries.
This kit is the right buy for contractors and serious DIY users who own or are buying bare M18 tools, or who need more power for demanding cuts and fastening.
