New Makita BL4040 XGT 40V MAX Li-Ion 4.0 Ah Battery Pack DC40RA Rapid Charger ABOUT MODELThe 40V max XGT 4.0Ah Battery is engineered to outlast the competition. XGT Batteries feature an advanced design with an impact-resistant outer case and shock-absorbing inner-liner that are engineered to protect the battery in harsh jobsite environments. XGT Batteries also feature rigid rails with impact-resistant construction to secure the battery to the tool during high-demand applications.40V max XGT Batteries are equipped with smart technology. The digital communication within XGT Batteries optimizes performance to provide up to 2X longer sustained power under heavy-load applications. The digital communication within XGT Batteries and Chargers (sold separately) actively monitors and protects against overload, over-discharge and overheating. This advanced charging technology helps optimize battery life and deliver a faster charge. The battery reaches a full charge in only 45 minutes or less.ABOUT MODELThe XGT Rapid Optimum Charger offers key advantages for Makita 40V max XGT cordless tool users. The exclusive dual fan design cools the battery (sold separately) by circulating air through the battery 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.INCLUDES:(1) BL4040(1) DC40RA ABOUT MODEL The 40V max XGT 4.0Ah Battery is engineered to outlast the competition.
