Build your own Makita tool kit with the 18-Volt Lithium-Ion Battery and Rapid Optimum Charger Starter Pack. Makita offers over 225 cordless tools that utilize 18-Volt lithium-ion batteries， most available as \"bare tools\" (tool only， no batteries or charger included). Pick up the Makita Battery and Rapid Optimum Charger Starter Pack， then purchase the 18-Volt \"bare tools\" you need to get the job done. It's an ideal way to start building a Makita LXT Cordless System. Makita 18-Volt 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 system powered by 18-Volt lithium-ion slide-style batteries.
