The MAKDC18RC fast charger, also known as the Makita DC18RC Li-ion 7.2 / 14.4 / 18v LXT Charger, uses Intelligent Charging Technology to control current, voltage and temperature to maximize the battery life.
The DC18RC can charges a BL1830B 18v LXT 3.0Ah battery in approximately 22 minutes - and to the fullest charge. The MAKITA DC18RC has a cooling fan and Active 3 Controls. This means 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. As a result, high temperatures occur in the battery, so that the battery life is extended, and the charging process is accelerated.
