ROCKSTER / ROCKSTER AIR: The battery does not charge and/or discharges very quickly. Is this a defect?

The ROCKSTER and ROCKSTER AIR have a central control unit which also stores the battery status. In some cases, however, the software may not process this information accurately.

If you suspect that the battery of your ROCKSTER / ROCKSTER AIR is not charging properly and/or is discharged very quickly, even though the device was actually charged for a long time beforehand, resetting the control unit (Teufel ROCKSTER reset / Teufel ROCKSTER AIR reset) can help. To perform the reset, disconnect the integrated battery from the device for approx. 60 min. 

 

Teufel ROCKSTER Reset / Teufel ROCKSTER AIR Reset: Step-by-Step Instructions

  • Unplug the power cord from the wall outlet.
  • Remove the six screws of the battery compartment cover (without affecting the warranty claim, of course).
  • Remove the battery compartment cover.
    In the battery compartment you will see the battery with a red and a black cable with connectors.
    • The red cable always belongs to the positive pole (+) of the battery.
    • The black cable always belongs to the negative pole (-) of the battery.
  • Push the plastic cap from the lug onto the cable so that you can see the lug.
  • Using a small pair of pliers, gently press down the latch (4) and pull the connector (1) off the battery.
