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 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 18 V lithium-ion slide-style batteries.
