The Most Powerful, Fastest Charging, and Longest-Lasting Battery in M18™ History.
Experience a new era of cordless performance with the Milwaukee M18™ REDLITHIUM™ FORGE™ XC8.0. This battery represents a massive leap in power density, delivering the high-current output of the massive 12.0Ah High Output battery but in a smaller, lighter XC size. Built for the professional who demands no downtime, the FORGE™ XC8.0 is the fastest-charging battery in its class, reaching an 80% charge in just 15 minutes when paired with the Milwaukee M18™ Dual-Bay Super Charger.
With the longest cycle life of any REDLITHIUM™ battery, the 48-11-1881 isn't just a power upgrade—it's the best long-term investment for your M18™ FUEL™ tool library.

Milwaukee M18™ FORGE™ XC8.0 (48-11-1881) Charge Time Guide
The table below shows the time required to reach a 100% full charge versus an 80% "Ready-to-Work" charge across Milwaukee’s different charging platforms.
Charger Model 80% Charge (The "Quick Swap") 100% Full Charge Advantage M18™ Dual Bay Super Charger 15 Minutes 25 Minutes The Best Performance. Built specifically for FORGE™ tech. M18™ & M12™ Rapid Charger 35 Minutes 45 Minutes 2X Faster than a standard charger. M18™ & M12™ Standard Charger 70 Minutes 85 Minutes Reliable, but best for overnight charging. Why the 80% Mark Matters
Lithium-ion batteries charge fastest from 0% to 80%. The last 20% is a "trickle charge" to protect the cells. For high-demand pros, the 15-minute mark means you can drop a dead battery on the Super Charger, take a quick coffee break, and have enough power to finish the job before you're even done with your drink.
COOL-CYCLE™ Technology: No Waiting to Charge
One of the biggest frustrations with standard batteries is the "Hot Pack Delay"—where the charger won't start because the battery is too hot from heavy use.
- FORGE™ Advantage: The XC8.0 features internal high-speed cooling. When used with a Super Charger, it actively manages heat, allowing the battery to start charging immediately even if it just came off a high-drain tool like a Mag Drill or Grinder.
Recommended Charger for this Battery
To get the most out of your 48-11-1881, we highly recommend the M18™ Dual Bay Super Charger (48-59-1815). It is the only way to achieve that record-breaking 15-minute turnaround.
