The DC18RC uses intelligent charging technology to control current, voltage and temperature to maximise battery life. Features: -Has a cooling fan and 3 active controls, meaning that during the loading of the charging voltage, charging current and temperature is held in the holes -The cooling system blows cool air into the battery, which results in high temperatures occurring in the battery, accelerating the charging process Specification: -Power Source: 110v -Compatibility: 14.4V/18V LXT Batteries -Charge Time (1.5Ah): 15 mins -Charge Time (2.0Ah): 18 mins -Charge Time (3.0Ah): 22 mins -Charge Time (4.0Ah): 36 mins -Charge Time (5.0Ah): 45 mins -Net Weight: 820g -Overall Length: 185mm
