What is the expected voltage reading for the 12 V battery? VARTA ...
Ours seems to be jumping around quite a bit 12.24 to 12.30 or so
Charger is plugged into car, but scheduled to not start until early morning.
Car is 22 months in service, only about 5000 miles.
One reason for concern is wife had car out, would not start up, EPC light on dash. Then after a while it worked.
Next day – car had charged overnight, we let it rest then rechecked the voltage –
Initially, having opened the door to get to hood release, we saw 12.23 and heard a (fan?) motor run sound.
Then after a while that sound stopped, and the voltage started climbing - reached 12.70
Now, 6 hours later, we see 12.65 (car undisturbed in the interval)
So apparently opening the door starts some current drain, dropping the voltage temporarily.
Seems the battery is probably OK.
Wonder if the 12V charging apparatus is intermittent ...
Still unexplained is the EPC indicator and failure to start operations.
