This kit contains 4x Makita BL1860 18v 6.0Ah Li-Ion batteries with charge indicator LEDs, a DC18RD twin 18v intelligent charger and a MakPac 3 stacking case plus inlay. The BL1860 18v 6.0Ah battery is engineered to give more run time (twice the run time of the Makita 3.0Ah LXT battery), but with the same weight and dimensions as the lower-capacity 3.0Ah, 4.0Ah, and 5.0Ah LXT batteries. It reaches a full charge in only 55 minutes (with DC18RC / DC18RD fast chargers), the fastest charge time in its category. Includes a battery capacity indicator LED so you know how much charge is left. The DC18RD charges two 18v Li-Ion batteries simultaneously. The rapid charge technology selects the optimum voltage and current and temperature is controlled by the forced air system that circulates air through the battery to prevent overheating. and a full charge sound alert confirms when the charge cycle is complete.
