If your DemerBox battery isn't working properly, we may need to fix it. Before opening a support ticket, let us try to solve the issue with the following walk-through guide. 


Step 1: While unplugged from your DemerBox, plug your DemerBox charger into a wall outlet.

Does the charger light turn green? 

  • If yes, go to Step 2.
  • If no, please confirm that your wall outlet has power. If the wall outlet definitely has power and no green light appears on the charger when plugged in, please open a support ticket so we can send you a new charger. 
  • IMPORTANT: DO NOT USE A NON-DEMERBOX CHARGER to charge your DemerBox. We use a 12.6V charger and a different voltage can ruin your DemerBox's battery and power system.


Step 2: With your charger plugged in to the outlet, connect your DemerBox to the charger.

Note: You can snake the charging cable through the Port Hole to connect to the battery charging port. This will allow you to fully close the DemerBox and play music while the battery unit charges.


Step 3: Press the power button. Did the DemerBox turn on?

  • If yes, go to Step 4.
  • If no, it's likely that your DemerBox is having battery issues. Please open a support ticket above so we can assist you further.


Step 4: After turning your DemerBox on, did the light on your wall charger switch from green to red?

  • If yes, go to Step 5.
  • If no, it's likely that your DemerBox is having battery issues. Please open a support ticket above so we can assist you further.


Step 5: Leave your DemerBox plugged in to the charger for 10 minutes. After 10 minutes charge time, disconnect the charger from the DemerBox.

After the 10 minutes has passed, disconnect the charger. Press the power button. 


Does your DemerBox turn on now? 

  • If yes, your battery was flat. Reconnect the charger to your DemerBox and allow it to charge until the charger light goes from red to green. This indicates a full battery. It will likely take 4 to 5 hours to complete the full charge.
  • If no, your DemerBox's battery is bad. Please open a support ticket above so we can provide further assistance.
