Hi every one. Have a question that really isn't Bird related. Wife's car is a 04 Sable. It was hard starting yesterday. It would crank for a little bit(10- 15 seconds) before it started. Then the outside temp read out disappeared from the dash. What should the battery read when it isn't running? Right now it is about 12.6 volts. Running it is 13.7. Is the battery going south? Thanks, Barry
