Question

Battery volatage reading???

Shouldn't a fully charged battery be ~13 or 13.5V? Mine is reading 12.8 after being fully charged (as per trickle charger).

This semms low to me. Is there something wrong?

Sounds good. Mine's at 12.5v.

I think that 13.5v you expect is when the car is running and the alternator is charging the battery. That's a check of the alternator and voltage regulator.
