2011 tahoe intermittent starts. Had battery checked and shows 12.47 volts not running and 14.8 volts running. Can boost and starts immediatley. Can set overnight and start fine but may turn off for 5 minutes and will not start.

 

I’d recommend taking the battery in and having it load tested. How old is it.

SD

 

I will take it in tomorrow and have it tested. Original battery from 2011.
​​​​​​​Thanks.
