battery problem, AC Delco

[Dave92270]

Hi guys,

it seems that my battery suddenly died on me (in 2 days without any warning) - yesterday I noticed somewhat weak start but it started, and apparently recharged after short drive enough for repeat start on the way back from the store. Tonight I tried to start, and this time no chance, just buzzing... I checked out the battery, it is the original AC Delco that is supposed to be maintenance free? (no distilled water needed according to page 345 in the manual?). My vehicle was built late '06, is this common problem? I never had dead battery in 2 years in any vehicle I owned... maybe it is something else electrical possibly? Oh, my Onstar reports 100% everything perfect, haha.

I'll jump start (hopefully) the truck tomorrow and take it to the dealership to have a look - is the battery under warranty BTW?

Any thoughts? Thanks!

The best thing to do is buy a Optima Yellow Top Deep Cycle Starting battery. I have a 08 Alpha and went through 2 factory batteries in the first 2 months!

The stock battery is undersized. Get a decent battery and replace it...

The Plastic housing and base is also too small. Throw it out. However the metal tray and strap with it are good for any size replacement. Use a 8mm ratchet to remove hold down bolt on strap. Get a maintenance free type since the hold down strap is wide. Strap will cover caps on standard battery.

Good Luck!

my battery went at 35000 miles ...they replaced it for free, no pro-rating...

much cheaper then an Optima...!

and they gave me a free loaner for the day while they anal-ized the problem !!!

Thanks for info; I guess that I'll take the vehicle to dealership and try to get a new free battery. If they'll replace it with the same one, I'll probably buy a better battery some day soon - to make sure this wouldn't happen again. Well, at least now I really believe it's nothing else electrical, just most likely a crappy battery....

OK, so it turned out a bad battery - I took the truck to dealership today, they tested it "with Midtronics" and battery "failed with bad cell". New battery runs fine, all free of $$ charge... I'll have to lok which battery they installed, probably same model, according to service slip/workorder it is P/N 86-7YR, so another ACDelco.. I guess I'll eventually go ahead and buy Optima...

Why our sweet trucks come out of the factory with such a POS battery is a mystery to me.

Is a weak battery the reason for my headlights to dim when raising and lowering the windows?

Shoot there ain't a part on any non-exotic car out there that didn't come from the lowest bidder..
