Build your own Makita tool kit with the 18V Lithium-Ion Battery and Charger Starter Pack. Makita offers over 100 cordless tools and most are available as "bare tools" (tool only， no batteries or charger included). Pick up the Makita Battery and Charger Starter Pack， then purchase the 18V "bare tools" you need to get the job done. It's an ideal way to start building a Makita cordless tool line-up. Makita 18V Lithium-Ion batteries resist self-discharge so theyre 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 worlds largest cordless tool line-up powered by 18V lithium-ion slide-style batteries. Includes (1) 18V LXT 4.0 Ah lithium-ion battery and (1) rapid charger.
