Dewalt DCB102BP Battery Charger, Li-Ion, Charger Output Voltage: 12.0 to 20.0, Number of Ports: 2

These tool batteries fit any series of DEWALT cordless tools with the same voltage. For example, a 20V MAX* battery or a 20/60V FLEXVOLT battery will work with 20V MAX, MAX XR, and Atomic series tools. MAX XR* batteries are premium batteries with more capacity than standard MAX* batteries. 20/60V FLEXVOLT batteries automatically switch voltage to match the power of the tool they are paired with. They provide extended run time for 20V tools and ample power for 60V tools. The battery capacity listed for FLEXVOLT batteries is the amp-hour (Ah) rating when operating at 20V. This capacity is reduced when operating at 60V. Tool batteries of the same voltage and series may be available in different Ah ratings. Batteries with higher Ah ratings have greater power storage capacity but are heavier than those with lower Ah ratings.
