A:AnswerThe Nikon COOLPIX A300 digital camera uses the Nikon EN-EL19 Rechargeable Li-ion battery, which can be charged a couple of ways. One way to charge the battery is by leaving it in the camera and connecting the camera to the EH-72P Charging AC Adapter and plugging the adapter into a power outlet. Another way is to leave the battery in the camera and connect to a running computer with the provided UC-E16 USB Cable. Additionally, the EN-EL19 Rechargeable Li-ion battery can be charged externally with the optional MH-66 Battery Charger. When charging the battery by power outlet with the EH-72 Charging AC Adapter make sure to change the setting for "Charge By Computer" to "Off" in the settings menu so the battery receives a proper charge.
