Makita BL1860B 18v LXT 6.0Ah Li-Ion Battery More Run Time - Same Size and Weight! The new 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. This 6.0Ah battery will set new standards in run time, particularly when used on efficient brushless motor tools or in tandem on select Makita \'X2\' - Twin 18v tools. Makita 18V X2 LXT (36V) cordless tools are powered by two 18V batteries, and are engineered to deliver corded power and run time for select highest-demand tools like saws, blowers and trimmers – but without leaving the 18V battery platform or investing in heavier, high-voltage batteries.
