Rechargeable batteries usually come with a partial charge. We recommend you fully charge whatever battery you have before the first use. If you think your battery is not charging fully, completely discharge the battery and then charge it back up again.

How To Charge
Plug the charger into the wall. The LED light(s) on the charger should illuminate green. When the battery is connected to the charger the light changes to red. When the battery is fully charged, the LED light on the charger will turn green or flicker between red and green.
Please note: Some generations of batteries and chargers are not compatible and will not indicate if the battery is fully charged or is charging. If the LED light(s) on the charger does not change, then please allow 4 hours for a full charge. The lights on the battery may not turn on during charging.
