The M18 REDLITHIUM FORGE™ HD12.0 battery delivers extreme run‑time and power, giving M18 tools gas‑like performance. When paired with tools like the Gen 3 blower it can deliver up to 30 minutes of high‑output use on a single charge. The 12 Ah pack uses advanced cells and internal cooling to run cooler and charges to 80 % in roughly 15 minutes on a Super Charger.
