I had to replace my batteries last year in my 2021 2500 Cummins. It did start after 20 minutes on a charger but I was trying to go pick up our TT to run from Milton.
I bought Autozone batteries since I had to have them now.
When I tested the old batteries, one was good and one was bad.
Living in Florida I was told I got good life out of them.

 

[Billet Bee]

How about duralast platinum elite agm that come with a 5yr warranty, the odyssey warranty is only 3 years???

Guys worry WAY too much about replacement batteries. Each battery cost about 2 tanks of fuel. Go to Costco or Walmart, get the biggest battery they have that fits. You can pay 2 to 3 times as much and they don't last enough longer to ever payoff especially if you live where it is hot like Florida or Arizona. Even in temperate climates, which have the longest battery life, the expensive batteries don't pay off.

I don’t know about the heat thing .
I’m in south Florida, my 04 made nine years.
While my 14 only made it to eight years.
Both factory mopar batteries.
My 14 got a Napa AGM, as they were the closest,and on sale.

I have got ten and 12 years out of batteries up here, but I take very good care of them and they are in a temp controlled garage. Despite us as outliers, the common experience matches the map. Most Costco U.S. batteries, and everyone else pretty much, have a max 2 or 3 year warranty becuase of the high heat states and not being able to have warranties that are different by region, whereas here in Canada Costco still covers the batteries for full replacemnt to 60 months and prorated out to 96 months, which is 9 years, because their Kirkland batteries last so well in our climate.

Before we pull the trigger on a pair of agm batteries, I found some stories last night talking about too make sure your vehicles charging system is compatable for both flooded lead and agm because the charging is slightly different. They said it's not too big of deal because you can always just go to a stealership and they can program your trucks computer to charge an agm properly, but I'd rather not do that. So what have y'all heard about this charging deal, is our 2020 ram 3500 6.7 hohd alternator compatable to charge an agm battery without needing to reprogram anything?
Note: We opted for the single alternator and not the duel alternator during our original build.

My truck is a 14 , I have been using an AGM for the past three years , with no issues whatsoever.

I did nothing special, just removed and replaced.

I saw that there were questions, but I could t find anyone on this forum who claimed they had issues .

However maybe others have dead different experiences.

I went from the standard OEM factory H7 730CCA lead-acid battery to an Odyssey H8 950CCA AGM battery with zero issues whatsoever.

A simple re&re was all I did with no resetting of the system, etc.
Zero issues!

I did notice my truck immediately started up much cleaner/crisper/quicker with this larger AGM vs the old stocker lead-acid.

There are many threads debating the charging requirements for lead Acid versus AGM.
AFAIC, if you're using your truck regularly, not too many short trips, the charging system in our trucks is adequate for AGM batteries.

No starting battery will survive too long with numerous short trips, especially with extreme temperatures.

I do occasionally use a trickle charger to top off the state of charge on the lead-acid battery, and understand the importance of using an AGM-compatible charger to do the same, if you choose to upgrade to AGM.

AlfaOBD has a battery type setting option, but I have yet to learn anything more than mine and others, with an OE lead acid battery is set to Battery ID4.

I've written to Alexey, and he has no information on this topic.





The 1500s come with an H7, lead acid or AGM, but the battery tray has a removable plastic block. After removal, the OE battery tray will accommodate an H8 sized battery. You would have to verify if the H8 sized battery is sufficient for your needs.

I plan to replace the OE battery with an H8 AGM battery immediately after it starts showing any subpar performance.

Tyvm ram driver for that link you posted, man that describes everything you'd about ever need to know about a battery.

Did you get your truck started? Like everyone else has said already I’m guessing your batteries are on the way out. These diesels take a bunch of juice to get started especially if the grid heater kicks on.

It's the batteries like everyone thought it was. We had pretty much given up hope for the rest of the day but still had left our little 6a charger on it. That evening decided to give it a crank and see what she'd do since it had been on the little charger for about 8 hours straight and she fired right up like it always had in the past, then wife took it for about a 30 minute spin to let the alternator finish charging it. When she got back we decided to not leave the charger hooked up all night ( because it's an ancient craftsman and I don't trust it) but decided to plug in the block heater and see if that helped it to start for this morning since the temperature was gonna be down around freezing, which we don't normally do until it's below 20*. Went out there this morning and it fired right up with no problem at all, so let it run for about 10 minutes. Then we decided that tomorrow we'd get some batteries if it started back up from only leaving the block heater on again, we're cautiously optimistic since it worked this morning.
So now the great husband and wife debate , do we get the duralast platinum elite agm with a 5yr warranty that I want or get the interstate h7 94r from Costco with a 3yr prorated junk warranty for a couple hundred bucks cheaper that she wants, but we all know who'll win this one, lol. I'd say their both about the same quality and been around forever but the duralast have a for real warranty not some staggered down backwards pyramid scheme. Now before yall give me crap about not getting the odysse agm's, we both can clearly see their the best from online research from this group and the web but we're just not wanting to commit to that high of price tag since they don't have a longer warranty to basically justify us spending so much more( in our minds anyway).
So stay tuned untill tomorrow and I'll let yah know if it started and that she won the great husband and wife debate ,lol.

Your wife is smarter than you, just like mine is smarter than me. Buy the cheap batteries, you can pay for two sets for the cost of the next ones up, warranty be damned, and 4 sets for the price of the Optimas. There isn't even a debate as to the right move.

No offense taken brotha because I agree she's definitely the smarter one of this bunch. Warranties are important to me but she can't stand spending money on a warranty that you'll probably never use. It's a gamble either way and she's the gambler, not me I'd rather throw in a few hundred extra bucks too have peace of mind. she's like you and would say for the higher price your gonna pay for the battery that has a good warranty, if you just buy the good cheaper battery and it fails after 2-3 years then you could just buy a new one for less then you woulda spent on the great batteries with the good warranty. I'll argue my view for so long but I ain't no dummy, I know how easy or hard life can be haha haha. We just spent $4000 on the rv batteries that i wanted this past year so I won't argue this one to hard

ISSUE RESOLVED:
Got up this morning and told my wife that you know I'd chose the duralast with the longer and better warranty but if she wanted to make the call on either the duralast or the interstate's from Costco then I really don't care all that much and whatever she decides I'm good either way. So it was off to Costco for 2 interstates h7 94r and we got those changed out later. Everything appears to be gtg know and hopefully we won't have to worry about batteries for another 5 years, fingers crossed.
Ohhh, before going to Costco the truck fired right up this morning since we left the block heater plugged in all night to make it easier for the lower voltage batteries to turn it over.
I just wanted to thank everyone who chimed in and offered their much appreciated advice and opinions. We both know the odessey's would of probably been the best battery and route to go but we didn't want to spend that much and I couldn't get past only receiving a 3yr warranty for a higher price tag, so we'll see how these interstates hold up.
Thanks again.
