    Alternator issue maybe?

    Hi guys I have 2008 cts with a new battery. I notice when u used my tire inflator or the key turned with engine off 5-10 min it drains my battery dead. requires jump to start engine. I Usually see volt charging display at 14 plus volts however i notice yesterday it was on 13. Could they be something going on with alternator or is it my battery? Any input would be greatly appreciated. I did not buy the battery myself the used car dealer put in new battery it looks new anyway.

    Alvin,

    Sounds like your battery or maybe even a bad battery connection. I would take it to a local parts store and have the battery load tested. You may have been given the wrong size battery or a used battery. Batteries in our cars will look new, even if years old, because of the rear trunk location.

    Let us know what you find, good luck, Marv
