# Battery Charge Indicator on the Rechargeable Battery

Note: Not all battery types have a battery charge indicator.

The LEDs on the battery charge indicator on the rechargeable battery indicate the state of charge of the battery. For safety reasons, it is only possible to check the state of charge when the fan is not in operation.

Press the button for the battery charge indicator on the rechargeable battery to show the state of charge. This is also possible when the rechargeable battery is removed.
