Battery(s)

Well, 2012 to 2022...not bad for factory battery and second Deka battery (I run dual batteries).

 

Just bought two Diehard Golds from Advance, $400!!  Not only is gas expensive!

Replaced the 2 batteries in my '11 3500HD a month or so back...right at $450 (Auto Zone was the only store in town that had 2 of the same batteries in stock...it was going to take about a week at other stores in town to get the 2nd battery in)

To add insult to injury, it was the slightly newer by a few months (and I thought better) Deka battery that died...the OE battery is taking a charge (the other battery dragged it down) and load tests perfectly fine!

 

They had multiples of each option (agm, platinum, gold, and silver Diehards) in stock for mine, but I think that 6.0l battery (group 48?) fits a lot of platforms.  

 

It just gave me both sticker shock and amazement the OE battery is still kicking.

Those size batteries are only like $160-170 each locally here. Not the cheapest but also not the most expensive out there as far as price point/warranty. Not a huge savings over the $400 you spent but enough lol

We see prices bump up and down $10-20 at a time too.

I could have gotten cheaper, even really cheap, batteries; but I stayed middle of the road.  Something decent with a good warranty...

 

The cheap ones were around $100, the expensive ones were around $250.

I put a couple of ACDelco 48AGM batteries in my 2012 3500 last year.  Got a good deal on Amazon.

I never even gave Amazon a thought.  I needed the truck this weekend, so had that urgency on my mind.

 

I guess if you think about it...$400/ten years is really only $40/year.  Although I remember buying truck batteries for $25/each!

Yeah, that's the thing, I wasn't in a hurry!  Amazon has AGM type batteries because there is no problem shipping them, but I don't think they carry wet cell type.

[sdeeter19555]

I've heard both good and bad with regards to AGM...they don't like overcharging being one bad.  My truck occasionally charges at 15.1 or 15.2VDC, I assume it is doing that desulfation cycle but is that considered overcharging?  I thought I also remembered someone stating the GMs need the computer told that they have lead acid or AGM batteries for that reason?

Some late model vehicles actually do have an ECM setting for AGM batteries, but it doesn't matter in the older trucks.  Rule of thumb is if the truck has a charging amp sensor (clamps around the positive cable near the battery) it might need to be programmed for AGM batteries.  Always check the service manual.
