How do I know my battery is dead?
If the light flashes when you use it, it is a sign that the battery is about to run out. Simply screw the USB charger to the battery and charge it for about 2 hours. If you think your battery is dead but it might be the cartridge, here’s how to test it:
Unscrew the cartridge from the battery and pull the battery. If everything works, the battery will light up at the bottom. This indicates that the cartridge is clogged by the cold. You can heat the cartridge standing upright in the tube at about 60°C or with the lighter briefly until the extract is liquid again. After that you can pull it again with pleasure and enjoy the aroma. Attention: The battery is already fully charged before the first use and can be used directly.
