Makita BL1840 18V LXT Lithium-Ion 4 Ah Battery
The new 18V LXT 4.0 Ah battery delivers even more run time, but with a minimal increase in charge time for maximum efficiency. Industry-leading performance and compatibility, with a battery that spends more time working and less time sitting on the charger.


Provides up to 35% more run time per charge compared to the 18V 3.0Ah battery (BL1830). Reaches a full charge in 40 minutes or less on the Makita Rapid Optimum Charger (sold separately). Compatible only with Star Protection tools, indicated by the Star Symbol and/or Yellow Battery Receiver under the tool. Battery delivers consistent power and run time in extreme temperatures, even in winter (-4°F/-20°C). STAR Protection Computer Controls allow the tool and battery to monitor conditions during use and exchange data in real time to protect against overloading, over-discharging and overheating. The Makita Rapid Optimum Charger (sold separately) communicates with the battery’s built-in chip throughout the charging process to optimize battery life by actively controlling current, voltage and temperature. Impact-resistant outer case and shock-absorbing inner-liner are engineered to protect the battery. Sixteen contact terminals maintain a constant connection with the tool to help prevent power loss or fluctuation, even during high-vibration applications. Battery resists self-discharge and remains ready for use even after long periods of storage. Makita 18V Lithium-Ion is the world’s largest cordless tool line-up powered by an 18V Lithium-Ion slide-style battery.
