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 LXT® Lithium-Ion batteries charge faster and work longer than standard lithium-ion batteries, giving you and your cordless tools unmatched performance and productivity to take on the most demanding applications. The Makita 4.0Ah battery combines more run time (35% more run time per charge than the Makita 3.0Ah battery, BL1830), with a category-leading charge time of only 40 minutes so it spends more time working and less time sitting on the charger. Makita 18V Lithium-Ion batteries resist self-discharge so they’re ready for use even after long periods of storage. 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. The Rapid Optimum Charger offers key advantages for Makita 18V Lithium-Ion cordless tool users. The exclusive built-in fan cools the battery by forcing air through the battery's air vents during the charging process for faster charging. The charger communicates with the battery's built-in chip throughout the charging process to optimize battery life by actively controlling current, voltage and temperature. The result is category-leading battery charge times, which means the battery spends more time working and less time sitting on the charger. (Note: also charges Makita 14.4V Lithium-Ion batteries.)
