1. Battery is on its way out, is it better when is been run and the outside air temperature has gone up
     
  2. I have 2-3 months I have changed the battery they was 30 procent. Problem not solved :worried:
     
  3. Not fixed the car going under the 9 volt after start can any help me ?
     
  4. It's going to be your alternator then, voltage regulator, normally they go high voltage not low, but anything is possible.
    Is that 9 volts at the battery ????, there's nothing to say that your new battery is good, get it checked just to rule that out.
