The DCB132 Dual Port Charger is compatible with existing DeWALT 10.8V to 18V Li-Ion XR batteries and the latest 18V/54V DeWALT XR FLEXVOLT battery. It features two 4.0Ah charging ports; you can charge an 18V and a 54V battery side by side. A bright LED indicates the charge status: charged or charging, or if there is a power problem and whether the battery is too hot or too cold to charge. Internally the circuits have a conformal coating, protecting the electronics from dust and moisture. The charger is wall mountable to keep it off the bench with the batteries safely out of the way while charging.
