Forget about voltage when the battery is idle (no high amp draw).
Check the voltage with a GOOD METER (no dashboard gauge) when you are cranking the car. The battery might have a 'dead cell'. They can show a normal voltage when idle, but when load is applied the voltage drops significantly. I used to be a DC power technician, so I have a clue.
