Featuring a category-leading charge time of only 40 minutes, the Makita 4.0 Ah battery (BL1840) combines more run time (35% more than the Makita BL1830 battery) with convenience, thanks to its integrated L.E.D. charge level indicator.

Makita, the innovation leader in cordless tool technology, has designed the world's cordless tool line-up powered by an 18V lithium-ion slide-style battery. This advanced battery technology, combined with STAR Protection Computer Controls, ensures improved tool performance and extended battery life. STAR Protection is a communication technology that allows the tool and battery to exchange data in real time, monitoring conditions during use to protect against overloading, over-discharging, and overheating.

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, even in hot weather conditions, thanks to its built-in fan that cools the battery.

The 18V LXT 4.0Ah battery (BL1840) is compatible only with Star Protection tools, indicated by the Star Symbol and/or Yellow Battery Receiver under the tool. Makita 18V Lithium-Ion batteries also resist self-discharge, ensuring they're ready for use even after long periods of storage.

In summary, the Makita 18V LXT Lithium-Ion battery offers unparalleled performance, delivering consistent power and run time in extreme temperatures, even in winter (-4°F/-20°C). With its faster charging time, extended run time, and advanced safety features, this battery is the perfect choice for tackling the most demanding applications.
