This package includes two high - performance 18V lithium - ion batteries. Key features: Integrated LED charge indicator helps you easily keep track of the battery's charge status. It offers up to 50% more runtime per charge than the BL1815 model. You can get a full charge in just 25 minutes or less. These batteries are only compatible with Star Protection tools, recognizable by the Star Symbol™ and/or a yellow battery receiver under the tool. They perform consistently in extreme temperatures, even in cold winter conditions as low as -4°F (-20°C). Equipped with Star Protection Computer Controls™, they're safeguarded against overloading, over - discharging, and over - heating. The impact - resistant outer case and shock - absorbing inner - liner protect the battery well. Sixteen contact terminals ensure a stable connection with the tool, preventing power loss or fluctuations, even during high - vibration jobs. They resist self - discharge and stay ready for use after long - term storage. Makita's 18V Lithium - Ion is the world's largest cordless tool lineup powered by an 18V Lithium - Ion slide - style battery. With Makita's advanced technology, the battery spends more time working and less time on the charger (charger not included). It comes with a 3 - year limited warranty.

Using these Makita 18V batteries is easy. Just slide the battery into a compatible Star Protection tool. Before using, check the LED charge indicator to know the battery's charge level.
