Replacement Battery

[EddieC]

My AC Delco battery is failing before it's 42 month "Free" replacement warranty expired and the (expletive) dealer who sold it to me refused to replace it only offering prorating it for very little credit toward a new expensive one. I called AC Delco who might make good but there is an issue caused by the dealer with the original paperwork, but the whole thing snafu that cost the dealer any further of our business.
I always had good luck with AC Delco batteries but it appears that the dealer sold me a superceded (old??) model that I asume sat on the shelf and therefore is failing early.

I have never had an issue with Walmart batteries or warranty replacement so here is the question; Is it worth spending $40 more to get an AGM with an additional year of free replacement or just stay with the standard (MAXX) lead acid battery? The two have very close specs relative to CCA and reserve cranking time.
So, in a seasonally cold environment, is there any performance difference or would I just be buying another year of warranty for the $40?

Would there be any compatibility issue with the AGM?

I wouldn't get aggravated over a battery. The charging system in our trucks was not designed to charge the AGMs as they require so they will not last as long as they could have.

Check another dealer and look on their website for coupons or specials. Oftentimes they'll even install it for free.

I paid a little over $200 for a 48GHRA battery last August (O'Reillys). My daughter's boyfriend bought one today for about $150, his cost, as he is dealership employee.

The batteries are date coded and it doesn't matter how old they are, the warranty begins on the date of purchase. Remember my earlier battery posts, new battery was dated coded for 2 months after I bought it!

my last set of Interstate AGM's lasted me almost 5 years (even with the California heat), they probably would have made 5 years+ but I could tell they were getting weaker
Costco sells them for around $170 with a 3 year warranty.
I believe that is $10 cheaper than a standard walmart battery, last time I checked anyway

I just put a WalMart AGM into my Tahoe. No paticular reason....it was on the shelf and I got it. Old one was still good...but needed a battery for something else and used it there....had an old wreck of a battery for a trade in. Tell ya what....them suckers are HHeeaavy ...

Any dealer should be able to honor that warranty and I just dealt with this last year. The new dealer didn't want to do the full longer battery test and the battery would just squeak by on the quick test. We had brought it in for a trans flush and specifically their longer battery test while they were absolutely slammed. They threatened that her truck would take longer and might even be an extra day or two if we wanted such a long test. I asked why it wasn't done as requested while they were performing other work on the truck and they had no answer. I then told them that we would be fine driving one of our 4 other vehicles and they were welcome to deal with keeping an extra vehicle in their bay/lot over the weekend as needed. Got a call 35 minutes later that we were getting a new battery and the old one failed as I expected and that they would love it if we could get it out of their way ASAP.

I will also say these new charging systems don't like sulfated batteries. I got a new Delco at our dealer and noticed it was charging over 15 volt constant, not once on a trip did it cut down to the 12.8 maintaining mode. I took a close look and that battery had been on the shelf for 8 months, manfu. date a couple months earlier than that. I put a new Non-AGM Walmart battery in it, looked at three stores to get the newest ship date, working great now. And, as above, that's one heavy chunk to get in that battery tray.

I put a Autozone Duralast Platinum AGM battery 3 years ago. I paid $250 and was able to change it in 30 minutes in front of Autozone using there tools. They offered to do it for me but I won’t allow anyone to do it because they can scratch or damage my fender or paint. Duralast and Diehard are the same brand. Diehard is a sears brand that was always the best to get. Previously I bought a GM 42 month Delco Gold non-AGM for $220 which Cadillac roadside bought to me when my original battery died. Roadside convinced me that AGM is not good for our trucks so I believed him. 8 months later the new Delco Gold battery failed and I lost the receipt. I was told I had to go to the selling dealer that roadside was sent from but I was 1200 miles from home on vacation. I was not about to call roadside every time I needed to go somewhere with my truck with my family on vacation. It is embarrassing since I always brag about how great my truck is. I went to Autozone and bought the Duralast platinum AGM and now 3 years later it is still perfect. I can go to any Autozone in the world when my battery fails and get a new battery under warranty or prorated at any location using my phone number. The Duralast also has a 140 hour reserve. I can clean my truck for hours and no loss of battery. Our trucks are fully compatible with AGM.
