Cause:
A piece of plastic strip was left behind because it was torn off while removing the plastic tab. No contact can then be made with the battery.
The plastic strip is not completely removed.
Or the plastic strip is torn off.
1. Unscrew the screw from the cover.
2. Remove the cover
(it may feel slightly sticky, this is due to the silicone rim on the inside).
3. In the corner between the battery and the contact point is the remaining piece of plastic strip, please remove it.
4. Screw the cover back on. Now the Solar’s contact with the battery will work for storing energy and lighting the LED in the dark.
