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 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.
