Our take on the MILWAUKEE 48-59-1881 M18 REDLITHIUM FORGE XC8.0 Starter Kit – 8.0Ah Battery & Rapid Charger, High Output Power

This is Milwaukee's M18 REDLITHIUM FORGE XC8.0 battery paired with the M18/M12 Rapid Charger. The 8.0Ah pack is built to deliver the same power as the larger HIGH OUTPUT HD12.0 in a smaller, lighter body, with Milwaukee claiming the longest life and fastest charging in its REDLITHIUM line. It fits the 275+ tool M18 system, so it suits owners of M18 drills, saws and outdoor tools who want more runtime and less downtime. Against standard REDLITHIUM packs it trades a higher capacity and FORGE cells for a heavier, bulkier battery; against the HD12.0 it gives up some runtime for less weight. Owners rate it highly, though the kit is a premium buy compared with a bare battery.

Cons
  • Heavier and bulkier than compact 2.0–5.0Ah packs

Questions and answers

Is this battery compatible with all M18 tools?
Yes. Milwaukee says the FORGE XC8.0 works with the full M18 system of 275+ tools. It also fits M18 chargers, and the included rapid charger accepts both M18 and M12 packs.
How does it compare with the M18 HIGH OUTPUT HD12.0?
Milwaukee says the XC8.0 delivers the same power as the HD12.0 in a smaller, lighter pack, but with 8.0Ah instead of 12.0Ah, so the HD12.0 runs longer while the XC8.0 is easier to handle.
What is in the box?
The kit includes one M18 REDLITHIUM FORGE XC8.0 battery and one M18/M12 Rapid Charger.
Does the rapid charger work with M12 batteries too?
Yes. The charger accepts all M18 and M12 packs and monitors cell voltage, temperature and charge status to reach a full charge.
Is the battery protected against damage?
It has a housing resistant to common oils, greases and solvents, and built-in REDLINK Intelligence protects it from overloads that could damage tools.
Is this a good upgrade from a standard REDLITHIUM pack?
For high-draw tools and long jobs, yes: it adds runtime and output. For light-duty work, a smaller compact pack is lighter and easier to handle.
