18V LXT Lithium‑Ion Battery and Rapid Optimum Charger Starter Pack (4.0Ah)

Build your own tool kit with the 18V Battery and Rapid Optimum Charger Starter Pack (BL1840BDC2X). The Starter Pack includes two 18V LXT 4.0Ah Batteries (BL1840B) and an 18V LXT Rapid Optimum Charger (DC18RC).

Makita offers over 350 cordless tools that utilize 18V lithium-ion batteries, most available as "bare tools" (tool only, no batteries or charger included). Pick up the Battery and Rapid Optimum 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 LXT Cordless System.

Makita 18V Lithium-Ion Batteries resist self-discharge, so they′re ready for use even after long periods of storage. The 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, 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 innovation leader in cordless tool technology, has the world′s largest cordless tool system powered by 18V lithium-ion slide-style batteries.

Tool users who unplug the cord with 18V LXT experience new levels of convenience, efficiency and productivity. created the 18V Lithium-Ion cordless tool category in 2005, and today it is the world′s largest 18V cordless tool line-up. ′s leading technology gives tool users unmatched performance and breadth of line, with innovation in motor and battery technology that is obliterating industry standards – and leaving old thinking behind. With high amp-hour batteries, efficient brushed and brushless motors, and 36V (18V X2) LXT technology, 18V LXT tools not only meet corded demands, they can exceed the performance of corded, all while remaining in a single cordless platform powered by the industry′s fastest-charging 18V lithium-ion batteries.
