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.

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.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.

      Electrical Problem - solved

      By CNH-320 · Posted

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
