- Green State
- The PowerCheck(Magic Eye) function displays the battery's state of charge at a glance. In this manner you can always keep informed about the energy supply of your battery and avoid surprises when attempting to get it started.
- Black State
- The battery's state of charge is not optimal anymore. The battery should be recharged. (Afterwards, the display switches back to green again, and you can keep driving without problems.)
- Transparent-light state
- The state of chage is insufficient for a reliable starting process. In that case, a replacement is necessary.
