Milwaukee M18™ Batteries: REDLITHIUM™ (2.0 – 12.0)

For the M18 lineup, we’ve given you the option to buy everything we have in our store, right here on this page. I spent weeks finding exactly which tools you should put in your cabinet, and the same applies to batteries.

First, you’ll want to decide which batteries you need. 

CP batteries are the lightest and most compact. 

XC battery packs, or  “Extended Capacity”, are for your mid sized tools. M18 XC batteries can provide tools a boost in performance, if only by a little bit.

HD battery packs, or “High Demand” are for the longest use times, and run less hot. This is for stuff like table saws, miter saws, etc.
