When the battery is fully charged the light on the charger goes out, usually about an hour after the last light on the battery has stopped flashing.

The battery is fully charged when the lights are all solid -when the last bar stops flashing.

It will switch off completely 30-60 minutes after this happens but you dont need to wait for that.
