My older Delcos, like yours were fine. Recently though I had two premature failures. 2007 Cadillac and 2009 Chevy. Both failed in less than 24 months. My friend, who is a service advisor at Cadillac, told me that in the last few years, he has seen an increase in early anDelco failures as well.
The one from my wife's 03 was still functional up till last summer and something over 175K miles, I replaced it before winter because I figured it had lasted long enough, only lights left on drained once. That said a lot can change between 03 and 09 far as quality of components used.
IMO when battery shopping choose a retailer you like, because if you have a problem they are who you have to go to. I have not bought many batteries but have bought Walmart and Advance Auto stuff and been happy.
Harrys SS, I hope you'll keep us posted on your progress! It's great that forum members were able to assist you. I realize you prefer the DIY approach, but please let me know if you ever would like to involve a dealer for service. I'm available via private message and happy to schedule appointments or call the dealer to follow up for you anytime!
they are small on these cars.. doesnt take a lot to kill them.. I have a valentine one hard wired in mine, then the phone charger. if you forget to turn them off they drain it dead in a day or so..
Both my old two had them replaced by the dealer. Bad cells? Dealer said there was a run of them with those problems.. This 12 model has died as well, but it was my fault. it snowed one night and took the sububran next day left the stuff on..
I usual run those autozone gold? i think they have a yellow top. Keep the recipet becuase they have like a 3 or 4 year warranty now. The sububran eats them like candy bars.. i get usually a year out of one.
I bought a Gold Autocraft from Advanced Auto Parts. Three year replacement. 84 months prorated. Over 600 CCA. 95 min. reserve power. The problem I had was putting it in. My son and I worked for 45 minutes before giving up. There is an IPS Mortorsports about a minute from us so I had them do it. I just don't have the patiance to do installs anymore.
Getting the battery back in to one of those cars is a bitch, I hate it. There is a certain way you have to finagle the damn things back in, and I have yet to figure it out completely, all I know is I eventually get it.
I just bought a Motomaster Eliminator Ultra from Canadian Tire, because they are $25 off. They are still pricy though, but it's rated at 925 CCA at 0 degrees celcius. It came up to $175 including taxes, but has a 5 year replacement warranty. k3:
