The Duracell 15-minute charger can recharge one to four AA or AAA rechargeable NiMH batteries in as little as 15 minutes. In order to be recharged, the batteries must be removed from the electronic device they are powering, placed in the battery recharger and then connected to an electrical power source. Once the batteries are recharged, they can be placed in any electronic device that uses AA or AAA batteries, such as digital cameras and toys.
Insert one to four rechargeable Duracell AA or AAA batteries into the battery bay of the charger. All of the batteries should be positioned so that the positive (+) terminal is facing up and the negative (-) terminal is facing down.

Rotate the electrical plug on the charger so the prongs are folded out. The prongs fold in so they lay flat against the charger when it's not in use.
Plug the battery charger into an electrical outlet. The red LED light on the charger will appear, indicating that the battery is charging. If the LED light is flashing, there is a malfunction and the batteries aren't charging.
Unplug the battery charger from the electrical outlet when the red LED light turns off, indicating the batteries are fully charged. The charging process can take anywhere from 15 minutes to two hours, depending on how many batteries are being recharged, the battery cell capacity, the condition of the batteries and the temperature.
