  If the indicator light is flashing on your GYS Battery Charger, there are several possible reasons. It could be due to polarity reversal, meaning the clamps are not correctly connected. Ensure that the clamps are properly connected. Another reason could be that the battery voltage is too high. Verify that the selected voltage matches the battery's voltage. A short-circuit in the clamps could also cause this issue; double-check their connection.

  If the indicator light on your GYS Battery Charger is illuminated continuously, it could be due to a charge failure, indicating that the battery cannot be recovered. In this case, replace the battery and press the button to restart the charging process. Alternatively, the ambient temperature might be too low for charging an LFP battery. Try charging the battery at a milder temperature or press the button to proceed.

  If the indicator light on your GYS Battery Charger continues to stay on even after pressing the button, it is likely due to thermal protection being activated. This means the ambient temperature is too high (above 50°C). To resolve this, cool the room and allow the charger to cool down.
