Milwaukee 48-11-1813 — M18 REDLITHIUM FORGE HD12.0 Battery

M18 FORGE HD12.0 battery with 12Ah capacity and COOL-CYCLE capability. Active cooling requires a COOL-CYCLE-capable charger; ordinary M18 charging compatibility does not imply that feature. This is the FORGE pack, not the older HIGH OUTPUT HD12.0.
