The 18 V LXT Lithium-Ion battery charges faster and works longer than standard Lithium-Ion batteries, giving you and your cordless tools unmatched performance and productivity to take on the most demanding applications. The 6.0 Ah battery, model BL1860B, combines more run time (two-times more run time per charge than the 3.0 Ah battery) with a category-leading charge time of only 55 mins so it spends more time working and less time sitting on the charger. For added convenience, it also features an on-board LED charge level indicator to monitor battery charge. The 18 V LXT 6.0 Ah battery is compatible only with star protection tools, indicated by the Star Symbol and/or yellow battery receiver under the tool. There are over 125 18 V cordless tools with star protection and more are on the way. 18 V Lithium-Ion batteries resist self-discharge so theyre ready for use even after long periods of storage. The rapid optimum charger is a smart-charging system that communicates with the battery during the charging process to monitor current, voltage and temperature. This advanced charging technology helps optimize battery life and deliver a faster charge. In addition, the charger has a built-in fan to cool the battery for faster and more efficient charging, even in hot weather conditions.
