To the OP...

I too have a 15 Ram with close to the same mileage. We had a few cold days here in S. LA and it was enough to do them in. I replaced both with AGM batteries from O'Reilly to the tune of $400. They gave no warning at all that they were getting weak. I went out one morning and , CLICK!

I went with Interstate AGM.

Are Interstate AGMs ever on-sale at a discount retailer to their standard pricing? Seems like they are uniform priced yearound, unlike other battery brands.

Side Question:
Are AGMs suitable as House batteries on my Class C coach? I've been using 2/Interstate wet batteries as my House batteries.

My 2008 would not start up one morning. So I put my battery jump starter on the truck. But it would not start. I then also attached my battery charger and placed it on 50 amp start. It took both to provide enough amps to fire up the glow plugs and start my truck. I replaced both batteries. DW ran my battery tester over so I could not check my batteries. I know it was my fault for leaving my battery tester on the driveway next to my truck while I was working on it.

Use a hydrometer. Make sure they have water and charge them up. Check again. They will let you know when they are starting to fail.

For diesel applications are the AGM batteries better than the lead-acid types?


AGM batteries ARE Lead Acid. just not a flooded cell battery.

Are they better? define better and decide what is important and then compare AGM strength and weakness vs. other batteries.

I've got a 2002 7.3 V8 Powerstroke turbodiesel that has tandem FoMoCo, batteries on it.

What brand AGM 12V batteries are others using?
