Cayenne Turbo (04) battery replacement

Recommended Posts

My car started acting weird upon start up, the "start engine" battery warning light appeared after I started car, then upon starting again it flickered and all setting were reset, clock reset to 12:00 etc.  I placed on CTEK charger tonight but I am pretty sure I need to replace my battery and was wondering if both the rear and front batteries are the same.  I have receipt for one of the batteries, it was a Duralast H8-DLG.  I recall replacing both batteries within months of each other and can recall which is which.


Thank you all!

the H8 battery is the main one under the driver seat.  That's the one you want to replace if you are having squirrely electrical issues.


How old is the battery?  I regularly plug in my battery to my ctek and i typically get a few years out of them.  First battery lasted 6 years, and actually i still have the battery powering my generator starter.  Second battery has 4 years or so on it, still going strong.


Definitely recommend running your ctek every week or so just to keep it topped off.
