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I always had good luck with AC Delco batteries but it appears that the dealer sold me a superceded (old??)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 ...
