The Milwaukee 48-11-2440 M12 REDLITHIUM XC4.0 Extended Capacity Battery is a 4.0Ah pack aimed at users who want materially longer runtime from M12 tools. Its XC housing is better suited to longer-duty applications such as lighting, cutting, grinding, and repeated fastening where compact packs require frequent swaps. Milwaukee lists the same larger physical dimensions as its other M12 XC batteries, so buyers should expect added bulk in exchange for more energy storage. It is a solid pick for M12 users who need longer uninterrupted runtime and do not mind the larger pack size.
What tools is the 48-11-2440 compatible with?
It is compatible with Milwaukee M12 cordless tools that accept M12 battery packs.
How much capacity does this battery provide?
This battery provides 4.0Ah of capacity at 12V for longer runtime than compact M12 packs.
Are charger time figures published for this battery?
No specific charge times were provided in the supplied data, so those fields are left null.
Why would I choose an XC battery?
The XC format is better when runtime matters more than keeping the smallest and lightest possible battery footprint.
Does it have a fuel gauge?
No. Milwaukee generally does not list a fuel gauge for this M12 battery.
What warranty comes with the battery?
The 48-11-2440 includes a 3-year limited warranty.
