# MAKITA BL1850B 18V LXT Lithium‑Ion 5.0Ah Battery

The MAKITA BL1850B 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 5.0Ah battery has a category-leading charge time of only 45 minutes, so it spends more time working and less time sitting on the charger.

The MAKITA BL1850B 18V LXT® 5.0Ah battery is compatible only with Star Protection tools, indicated by the Star Symbol™ and/or Yellow Battery Receiver under the tool.

The MAKITA BL1850B 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.
