Better get your alternator checked and that sounds suspiciously like my battery's behavior just before it died. I had several folks (like Advanced Auto Parts and others) tell me the battery was fine too. I almost got stuck in the middle of nowhere when I stalled it.

How do you know what % the battery is? Is there something in the car that tells you? Normally a battery is checked for voltage, not %...
Mine normally sits overnight at 12.40 to 12.55.

My battery charger has % readout or voltage. You just toggle the switch. 12.4 volts I have seen recently.

My factory battery failed at 22 months. I replaced with an Optima Red Top.

My Nov 06 built 07 Z06 just got a new battery under warranty. That sucker is a #@%$& to get out of the back! Took it down to my local Chevy dealer. They put it on the battery tester and it said to replace.

Batteries last about 3 years or so here in the desert. At least it died in the garage instead of on a road trip.

With all the electronics on these cars today I think its best to change the battery every 3 yrs at least. It will save you aggravation down the road..and a battery is probably one of the least expensive items to do on these cars....safe rather than sorry.
