Energizer Recharge Value Charger with 4AA Batteries. The Energizer Recharge Value Charger is designed to charge two AA batteries simultaneously; four will charge all four at once. If you insert four AA batteries and a red light appears on the face of the charger the problem is with your batteries not the charger. If that happens the Energizer Value Charger with Batteries must be placed on a flat surface of a table or a hard surface of a wall outlet. There's even a bad battery indicator LED. The Energizer Value Charger does not include the cost of the batteries.
