AGM battery?

[JV1976]

Need to replace my standard battery. Should I "upgrade" to an AGM? Any advice appreciated. 2014 1500 SLT, 5.7 Hemi. Normal electrical requirements . . .no winches, light bars, etc. on truck.

If it was mine, yes. No corrosion on the clamps or cables with an AGM.
All my tractors and equipment get AGM's as I have to replace them.

What LouM said above.. In my opinion they are worth the extra money.

A bit older and different vehicles, but my 2004 Jeep TJ didn’t do great with an AGM battery. AGM’S need a charge a bit higher than lead acid batteries. Does a 2014 Ram charge as high as needed?
All things aside the AGM in my jeep lasted six years before I replaced it. After sitting a couple of days it would be a bit slow turning over. It just made you wonder if it was gonna fail unexpectedly. The new lead acid battery in it now spins the motor over faster than the AGM even when new.
Just saying. If it’s designed for lead stay with lead.

 

[seems fishy]

I have an Oddessey AGM in my truck and I had an Optima AGM in another vehcle for years before that.They need to have a charger with an AGM setting or you can damage them.They are both very good batteries.Do your research.They cost a bit more but aside from being that,the extra money is worth it IMO.There are other AGM batteries that are on the market as well,to look at.I have used them for additional aftermarket audio systems. I use a 370amp alternator on the 2023Ram,as well

I also own a 2014 .
I changed mine to AGM a little over three years ago.
I have had no issues with the swap, and everything is still functioning properly.
I would recommend.
If you look at the bottom of your battery tray , there is a plastic bloke that holds the battery to one side of the tray. This is to secure the H7 battery,if you remove that piece you can step up to the H8 .
It is a good upgrade that costs nothing,unless the battery is a few more .
Use our search function to find others that have done it.

^^^ this
The only added expense is an H8 battery might be slightly more expensive but not much over an H7. Having a slight larger battery is easier on the battery itself and the alternator has plenty of capacity to keep it charged.

I have a 2500 cummins with 2 agm batteries, I do like them but whats everyones opinion on LiPo batteries? I have one in my wifes 2021 VW Jetta, Only had it now for 6 months now, other then it is light as can be I don't know that I have any good/bad or other experience with it

I changed my 2019 Rams battery to a AGM battery in 2024 and have had good results.
I did parallel up a deep cycle battery with jumper cables when I changed it out so that I wouldn't lose all of my settings. Worked great.

I replaced the AGM battery in my SxS with a Lithium, it was great in the summer months.
But, when they get cold they can't discharge fast enough to function as a starting battery.
In the fall turning the lights on for just a minute or bumping the starter a couple of times would warm the battery and she would start good.
Winter time I had to use a jump pack to get it started initially. Once started and running restarts within a few minutes were fine the longer between uses and starting the cooler the battery got the less capabilities.

I did the upgrade to larger H8 AGM over a year ago.

I've put an AGM battery in my IH 574 which is an early 70's tractor. It was switched to a Delco 3 wire self regulating alternator over 30 years ago. No issues with charging or starting

Also, when changing battery type, there is a setting that can be accessed by AlfaOBD where the battery type is selected. I have found nothing on anything that shows what types of batteries correlate with the numerical assignment in AlfaOBD.

I even asked (gasp) a service manager in a dealership and he had no clue either.

The settings are there, they obviously mean something (mine is set to 4 and I have an AGM battery) by effecting charge rate, from the computer, for the battery type / size, but it is also a national secret.

This is a great question, My original batteries were not agm as far as I know. I have never changed that setting because as mentioned they are just numbers I think it would be better to let the computer know because it changes that charge profile. My wife's 2021 Jetta I put a lithium battery in and the car started throwing codes I went in with a scan tool that has access to make changes and changed the battery type ot lifepo4 and no more conflicts or issues

In Florida the Lithium will probably work fine. In Canada during the winter, they suck.

As far as AGM, Regualr Lead acid last about 10 years here. I cannot see an AGM lasting enough longer to be worth 65% more new, it would have to last 17 years. If you look at the warranty, full replacement for 48 on Lead Acid, 60 on AGM, both prorated after the full replacement to 100 months.

In Florida, the heat is what kills batteries, it kills AGMs nearly as fast as it kills lead acid, so why pay the AGM premium.

Good point about the heat/cold problem, I grew up in North Dakota, specifically right along the northern edge so I understand the issues of battery lol. That being said your comparing a expensive name to a Costco house brand. I bought my agm batteries on amazon, they were $150 each

Costco batteries is all I use in every vehicle, including the ATV and Lawn Tractor. In Canada, you can't beat the price, and no one offers a warranty even close to as good as the Costco one. They also sell a top notch battery that lasts really well. I have tried a few of the "Top Name" brands like Optima. They don't last any longer and are quite a bit more money.

I agree, costco has top notch stuff, most of it is likely made right alongside top name stuff just without that brand name. I don't challenge your solution in the least, I was just pointing out costco brand stuff will be cheaper no matter what. you could get agm for less then that energizer brand though. if costco carries one even better.

I understand that heat can have negative effects.

However, the last two factory batteries lasted for 9 years in my 2004 , then 8 years for my 2014.

The 04 , was a construction use vehicle, it would be driven short distances,and shut off and restarted dozens of times a day .
In between it might have sat with the radio cranked for a couple hours.


I live in south fl. It is summer year round.

I was born in Pa., where it seemed like every 2 or 3 years was time for a new battery.

Maybe I have just been lucky enough to get one of those batteries that was properly assembled ?

Every time I see these temperature charts , I have to question the accuracy.

But my wife buys Asian cars , for higher mpg.
These tend to eat batteries for me.
If I get two years I feel like that’s about the best I’ll get.

Sorry, I mis-understood your post. The Energizer AGM I posted above is the Costco AGM battery listed for my pickup and the $329.99 price is the Costco price. Costco sells Energizer and Kirkland here, the Kirkland batteries are made by Energizer.
