These tool batteries fit DEWALT cordless tools of a compatible platform and matching voltage. For example, a 20V MAX* battery works with 20V MAX*, MAX* XR, and Atomic tools. MAX XR* batteries are premium batteries with more capacity than standard MAX* batteries. MAX* Compact batteries provide the runtime of standard MAX* batteries in a lighter, slimmer form. FLEXVOLT batteries fit 20V MAX*, 60V MAX* and 120V MAX* tools (which require two FLEXVOLT batteries). They automatically switch voltage to match the power of the tool they are paired with, and they provide extended run time for 20V 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. Batteries of the same voltage, platform, 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.
