Where we live, in the cooler climate it's probably the most ideal for battery life. I have had several yellow-top batteries, and AGM's. And many years of L/A batteries. The Yellow-tops do last a little longer, maybe a yr or possibly a tad more, although I've had some that lasted a lot less. But they cost almost twice as much as a lead-acid battery. AGM's are somewhere in between. I still do have a couple Yellow-tops (due to their compact size) but dollar for dollar the L-A batteries are the best value (based on my experience).

But in other environments (e.g. warm climates) L-A batteries don't live nearly as long, so maybe other technologies are better.

Walmart Batteries: I don't usually buy them, but it's essentially a JCI battery (like 80% of the batteryies out there). TOTL batteries use non-recycled lead and acid. Tests done on youtube that were pretty detailed, actually showed the Walmart batteries were a better value than the others (they cost a little less). But since they had a direct RAM replacement that's what I went with. I imagine other outlets sell the same battery with a different sticker.

Walmart good for general MX things. When I have to replace my OEM, will get Duralast Platinum from Auto Zone. Yellow topped Deka/Optima are available here locally
but they R pricey for sure.

2019 Ram 1500 5.7 non-etorque;


Duralast Platinum EFB Battery H7-EFB Group Size H7 770 CCA $209.00​

  • Part #H7-EFB
  • SKU #1070528


Optima AGM Yellow Top Battery DH7 Group Size 7 880 CCA $320.00​


So depends if U wana spend more, as OEM CCA for these R 730 CCA, and I have optional 180 amp alternator. As U can see, a bit more $$$ but U do get 110 more CCA if U need it. I do not have a cold problem here but a Heat problem, but both batteries are sufficient.

Here, the least expensive batteries are at NAPA often. Best part they are made in the US.

I just replaced mine even though the stock battery was still good - but at 5 yrs old, I really don't want a dead battery when traveling.
I went with a Eco Diesel size AGM battery but if doing it again would probably go lead acid.

My son had an AGM in his jeep and it wouldn't start on cold mornings any longer @ 2.5 yrs old. To warranty a battery is quite a feat now days, so my goal was to kill it. Several full discharges (to almost zero volts) and recharges later, I think it is stronger than ever!
Here AGM batteries do not like to be stuck in a low charge state and he mostly does short trips with days of sitting in between. He drove for an hour and the battery was sitting at 12.3 volts (key off not running). It is now sitting at about 13 volts since the discharges and charges. Even though his charging system is around 14 volts when running, this won't charge a low state AGM battery.

Quickie,
Is the OEM battery in my 16 hemi AGM or regular? Thanks
OE Battery was wet lead acid replaced with Absorbent Glass Mat (AGM)
I thought because I read specs that my truck was supposed to come with AGM.
AGM is about 7lbs lighter.
OE lasted 5+

Under the type in the specifications you posted it reads “wet” typically AGM are considered “dry” your comment about the battery being “heavier” also caught my attention, but probably because it’s a larger size ?

Yeah, I saw that. It's definitely AGM. AGM's aren't really dry either as they do have the electrolyte, just less of it.
More accurate would be spillable or non spillable, I would think. Probably just a typical specs error in the description.

This must be why they call them dry - even though they technically aren't dry.
An AGM (absorbed glass mat) battery contains a special glass mat separator that wicks the electrolyte solution between the battery plates. This material’s design enables the fiberglass to be saturated with electrolyte – and to store the electrolyte in a “dry” or suspended state rather than in free liquid form.
As the battery works, electrolyte is transferred from the glass mat to battery plates as required. The mat contains enough electrolyte for the battery to deliver its full capacity and – should the battery case become damaged or the battery is tipped on its side – its electrolyte will not spill.

It is much larger and felt it lifting it up over the fender.

Yes, be careful with wet and dry terminology, because conventional flooded cell lead-acid batteries are shipped dry. What that means is electrolyte is not added until it reaches final point of sale. This keeps batteries fresh until customer purchase. After electrolyte is added, the battery is called wet.

AGM batteries are always wet - they are filled with electrolyte at the manufacturer, then sealed for life. They have an internal recombinant gas valve that eliminates the consumption and evaporation of water. The fiberglass mats serve as a sponge for the electrolyte inbetween the lead mesh plates.

Here in Canada, you can get a flooded lead acid for about $200 vs 299 for an agm. Definitely get the larger H8.

When my OEM battery went out a few months ago I was a little shocked it only lasted a little over 2 years .. I called the dealership and they asked what battery I had, by the time I looked he already pulled my build sheet and saw that it was only a 730 amp maintenance free battery which does state on my build sheet, but he said my truck should of came with a group size 65 and 850 amp? Does that sound right ?

You still have a Generation IV Ram, which should have gotten a 730CCA battery. They stuck one even in my 2017 heavy duty truck with the 6.4L Hemi. Not sure what the original group size was.

Like most guys, I put in an AGM with 850 CCA, Group Size 94R, or H7 in euro-speak. Some guys put in the bigger H8 for even more amps, say it fits. I don't need the excess amps (no aftermarket electronic bells and whistles), so I stuck with H7. Starts faster, should last longer.

I had a time where I had no idea what a AGM battery was.
I thought it was a different type of Gel battery because they are rated as spill proof.
They have a longer history than I realized in the commercial /military markets.

My 09 1500 Laramie came with AGM. I don’t know what my 14 2500 SLT Diesel came with but I just replaced the Mopar ones from 2018 with ACDelco AGM H7 they were $168 no core charge on amazing. Blasphemy but I don’t care not like they make them. They are JCI just the Mopar ones I replaced. I only buy AGM batteries if I can help it. One thing about an AGM battery is they can be wrecked by being run down too far. I haven’t had this issue personally. I have an old yellow top I bought around 2008 as a blemish and that thing still works today even when I test it with load tester.

So my truck is 5 1/2 yrs old it has never not started and i live in cold snowy Ontario, Canada. I only started thinking about the battery because i just bought a NOCO with multiple outlets so i could charge several of my bikes at the same time. I also bought the NOCO lead so i could charge the truck too. I only drive it 2 or 3 times a week as i have a spare car which i use to spread out the mileage.
However i tried this week the NOCO on the truck and it charges all types of battery.
When i connected it to the truck it wouldn't go over 25% for some reason. So i used my other charger which took it all way up to 90% but no further. Truck starts fine. Hence i'm thinking now just incase about a battery rather than wait till i'm stuck somewhere.

I looked at the battery and its sounds same as some of you guys have
Part no. 56029635ac
730 CCA 80 AHR EN630 RC140
I know of OPTIMA batteries from back in the day when i used to work for a car audio place where we did Competition Sound off builds so i know they're awesome batteries. I'm happy to upgrade it, stronger can't hurt.

I have been thinking recently about what I will do to replace the battery in my RAM.
I really like AGM batteries and used them for years in a motorhome as the house batteries. However, I do recall that the charging voltage was different for AGM as opposed to a wet lead acid battery. There was a setting on my solar controller to accommodate the difference in charging voltage. As I recall the AGM's could handle any amount of amperage you throw at them. However they were voltage sensitive. Excessive voltage could cause out gassing and being a valve regulated battery there was no way to get water back into the battery.
I see many have switched to AGM in their RAM's. Seems as though the switch was a success as I do not see negative comments in it's regard.
Anyone ever investigate the compatibility between the AGM battery and the charging system in the RAM?
I have read about variable output alternators which I do not believe I have. Though I do have all the apparatus on the negative terminal that some youtube channels indicate as an identifying factor for a variable output alternator. I have also read that the onboard computer can and does make voltage adjustments.
Just curious as I do intend to move to the AGM.
Comments?

Have you read the reviews on Noco stuff? A lot of complaints about not being powerful enough for many batteries. Frankly their stuff is not very good. Project Farm did a review and they came in at or near the bottom there too.

Many of them come with AGM. I think it is based on trim level but not sure.

I think it started as a trend for most automakers in 2016 it was 67% of the vehicles and its been increasing from then on

U.S. Military invented the AGM Battery. Essentially, it's just a perfected lead acid battery. Spill proof, sealed for life, shock resistant, lasts longer, less degraded by cold. It just costs more to make.

But costs have come way down since 1st production as economy of scaled production has taken hold.
