The Makita 18V 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 Makita 6.0 Ah battery, model BL1860B, combines more run time (two-times more run time per charge than the Makita 3.0 Ah battery) with a category-leading charge time of only 55 minutes so it spends more time working and less time sitting on the charger. For added convenience, it also features an on-board L.E.D. charge level indicator to monitor battery charge. The 18V 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 Makita 18V cordless tools with STAR Protection, and more are on the way. Makita 18V Lithium-Ion batteries resist self-discharge so they’re ready for use even after long periods of storage. The Makita Rapid Optimum Charger (sold separately) 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. For improved tool performance and extended battery life, Makita created STAR Protection computer controls. STAR Protection is communication technology that allows the tool and battery to exchange data in real time and monitor conditions during use to protect against overloading, over-discharging and overheating. Makita, the innovation leader in cordless tool technology, has the world’s cordless tool line-up powered by an 18V Lithium-Ion slide-style battery. Note that model BL1860B-2 is a two-pack and includes (2) 18V LXT Lithium-Ion 6.0 Ah batteries.
