# Battery charge indicator on the fan

The battery charge indicator on the fan indicates the remaining battery capacity or an overload for a few seconds when the operating button is pressed.

LED | Capacity
--- | ---
3 × continuous green light | 76–100 %
2 × continuous green light | 41–75 %
1 × continuous green light | 16–40 %
1 × slowly flashing green light | 0–15 %

The three LEDs in the battery charge indicator flash quickly when the temperature of the rechargeable battery is outside the operating temperature range and/or the overload protection has been triggered.
