Hi Everyone, I was in such desperate need of a Battery so I wasn't able to shop around much....I did end up buying a MagnaPower 730 Cold Cranking Amps for my 2013 GMC Sierra for the winter. I have no additional accessories on this vehicle, only an after market Alarm...

 

Hope I made the right choice in power, I know very little about Batteries and was hoping I could get some feedback

 

Thanks Everyone

Better than your original

Thanks CC, yeh I think mine was at the end of it's life, I bought the truck a few months ago, used, so not sure what the Battery went through, because it was only 3yrs old (AC Delco)

Highest cold cranking amp battery you can fit in the truck the better! When purchasing a battery for your truck, a auto parts store/manufacture has a few options for your specs. In that case I recommend buying the highest cold cranking amp battery.

The biggest I could get locally easily was 775.... The one you got is better than stock and should work well.

That is a sales pitch, higher cold cranking amp doesn't make the battery a better battery ( well it does at first ), in order to get more cranking amps the manufacturer has to use thinner plates between cells, this makes these batteries susceptible to plate warpage under extreme cold weather which defies the purpose in my opinion because when this happens battery output is significantly diminished because distance between plates becomes non-equidistant. High cranking amp battery life is far less than a regular ACDelco battery that comes with your truck, and no I don't work for GM or ACDelco.

 

High Cold Cranking amp batteries are best used in Ambulances since they really need to start because lives depends on it, but their maintenance schedules replaces these batteries good or bad before every winter.

 

Sorry guys, been working with batteries for 40 years, big or small. My 2007 Cobalt still has the original ACDelco battery and still going strong, My wife's G6 still has the original ACDelco and going strong and we live in Canada where we hits -30°C (-22°F) regularly during the winter. Just before every winter I put the batteries on the battery conditioner and desulfation process. They just keep on ticking like the Energiser bunny. Now my newly purchased truck has had a transplant with a Canadian Tire ''Eliminator'' probably one of the most over commercialized low quality battery ever made. It's less than a year old and failed all by test. It still starts the truck for the moment but probably not if I left it parked for a week. Try to desulfate prove behond repair. I don't have the receipt since the previous owner put it in, but less than a year old and I'm positive it won't make it through the first cold night. Luckily I have an $80 battery on standby and it passes all test.

Thick or thin plates, the issue is usually sulfation that actually breaks up the plates. Thicker plates actually "hold" more power. Also, if thick plates are what you want, AGM batteries are usually about 3 times thicker, and have the mat to help prevent flaking to boot.

What do you mean by breakes up the plates? What sulfation does is coat the plates and makes them less conductive for electrons. Happens to all batteries that stay close to full charge. Start, recharge and stop type of thing. Your vehicle has no circuitry to detect this or a method of desulfation. Best way manufacturers found to avoid this was by leaving headlights on after shutdown and turning them on before getting into your car. ( I know you all thought they were doing this for your convenience ). This produces a small amount of de-sulfation before high current output to the starter of your vehicle and has proven to be a good battery maintenance procedure over the last 15 or 20 years. I de-sulfate my batteries late october and the proof is in the pudding, my 2 cars 07-08 are still on the same batteries. The de-sulfation process spikes the battery with high voltage, this makes the sulfate break apart and peel off the plates and dropping to the bottom of the battery where it lies until the end of the battery's life which on average should be about 7 years.

 

Deep cycle marine batteries don't have this problem as much while in use but the minute you store your boat and put your battery on a shelf , sulfation begins. That's why a battery minder is highly recommended.

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.

      AFM Disabler Question

      By Grumpy Bear · Posted

      Melling I believe is/was the OEM on the lifters who explored this problem some years ago. The white paper they generated on the topic indicated two items of note when I read it. 1.) They only fail on the switch. Prevent the switch, prevent the failure. 2.) The majority fail due to deposits messing up the timing of that switch. Anyway that's what I got from it.    Mine have always been active, 195K+ now, and my oil maintenance is surgically clean.    Of course this assumes good parts. That is no heat treat issue or machining flaws. I get comfortable that these issues are in the rearview mirror by about 30K. IMHO naturally.
