Low battery volts is this common
My battery voltage goes below 12V when parked for a few hours, sometimes as low as 11.2V. The puzzling thing is that the motor still starts immediately and the voltage rises to the normal 14V when running.
It has been doing this for more than a year and I can't understand why the battery hasn't died.
Does anyone know if this is common? Is there something strange about the battery chemistry?
