Check charge state of battery - AR54.10-P-1136-01A
Test instructions for disconnected battery:
- Connect the digital multimeter to the battery and read off the voltage.
Digital multimeter, see GOTIS

- Voltage: ≥ 12.5 V Battery OK
- Voltage: < 12.5 V Charge battery
- After charging, remove the surface voltage of the battery. To do so, switch on the driving lights for approx. 60 s.
In the case of batteries disconnected from the on-board electrical system, the procedure for removal of the surface voltage is described in a separate document (pay attention to the literature).
Generally, the following guideline values (ambient temperature approx. 20 °C) apply in the case of open circuit voltage measurement without current load (disconnected or removed battery):
| Voltage | Capacity |
|---|---|
| ≥ 12.7 V | 100% |
| 12.5 to 12.6 V | 80% |
| 12.2 to 12.4 V | 50% |
| 12.0 to 12.1 V | 30% |
| 11.5 to 11.7 V | 0% |
| < 10.5 V | deep discharged |
