The Makita DC18RC 15 Min/30-Minute Rapid Optimum Charger communicates with the battery's built-in chip throughout the charging process to optimize battery life by actively controlling current, voltage and temperature.
The Makita 18-volt LXT battery produces 280-percent more lifetime work with 2-times more cycles. Charging at any time will have no effect on the battery and a self-discharge keeps battery cells active and ready for use. It has a better fit and a longer run time (280 percent longer run times).
