makita bl1820b battery, 18 v battery, 2 ah, 25 min charging

The Makita 18 V compact Lithium-Ion battery charges faster and works longer than standard 18 V compact Lithium-Ion batteries, giving you and your Makita cordless tools unmatched performance and productivity in a compact size. The Makita 2.0 Ah battery delivers up to 50% more run time per charge than the Makita BL1815 18 V compact battery, with a fast charge time of only 25 mins for increased efficiency. Makita 18 V 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.
