Makita 18V LXT Lithium-Ion Compact Battery Pack 2.0Ah with Fuel Gauge BL1820B

The Makita 18-Volt Compact Lithium-Ion battery charges faster and works longer than standard compact lithium-ion batteries， giving you and your cordless tools unmatched performance and productivity to take on the most demanding applications. The Makita 2.0Ah battery combines more run time (50% more run time per charge than the Makita BL1815 battery) with a category-leading charge time of only 25-minutes， so it spends more time working and less time sitting on the charger. Makita 18-Volt 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 largest cordless tool line-up powered by an 18-Volt lithium-ion slide-style battery.
