Makita BL1860X2 18v LXT 6.0Ah Li-Ion Battery Twin Pack BL1860B-2 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. FEATURES Battery capacity indicator LED\'s show how much juice you have left on demand Double the runtime of a 3.0Ah battery (BL1830) with no compromise on weight or size Unbelievable 55 minute charge time with either DC18RC or DC18RD fast chargers Compatible with 18v tools if they have a star on the connector plate or if they have a yellow connector plate SPECIFICATION Battery Type: Lithium-Ion Battery Voltage: 18v Charge Time (DC18SD): 120 mins Charge Time (DC18RA/DC18RC/DC18RD): 55 mins Part Number: BL1860 / BL1860B / 197422-4
