I have been reading various posts about C5 batteries going dead if the car is not driven regularly. Some are attributing this to the many electronic items in the car that are always energized. Is this normal? Also, several have mentioned putting a charger on the car and having strange electronic noises and flashing interior lights. This all seems rather abnormal. :confused:

Wanna forget all the problems related to the " JUNK " Delco battery's ? Do as a great number of us have. JUNK the " JUNK " Delco, purchase an OPTIMA RED TOP and enjoy the car without all the impending problems related to the battery. Good Luck ! :cheers:

My battery died on my 2002 which is a daily-driver with NO additional devices added to the car. I was a skeptic, but the Delco's are indeed that bad... :yesnod:

I think the final numbers were something like five percent of the AC Delcos would eventually develop a leak. The problem with a battery leak in the C5 is that the battery sits directly above the electronics. Save yourself the worry and spend $100.00 on an Optima Redtop.

This is not just c5's. I have the same problem with a VW GTI VR6 that
is not driven much. I think modern cars present much more load to the
battery when the car is sitting idle. Get a VDC Battery Minder or
a Deltran Battery Tender and your problem is solved. Unlike most chargers
these can be left on for month after month with no danger of battery
damage.

Also, read your owner's manual. If you are not going to drive the car for 30 days disconnect the battery. (or use a tender)

If you habitually drive your car for short distances (not enough to fully recharge the battery), you should be using a battery tender regularly. :cheers:
