It's designed to take DuPont breadboarding wires, with a tip bent in a J to catch in the channel under each hole. Solder the correct wire (+ or -) to the pads on the charger board and slip in a battery. The charger will turn off when charged.

YOU MUST USE A LITHIUM CHARGE CIRCUIT LIKE ABOVE OR YOU WILL NEED A FIRE EXTINGUISHER OR A NEW HOME.
