2013 Ram battery

they should last longer than that,
I have a 2005 model dodge diesel and I just installed my third set, so who knows.

main thing, when you hit that starter you want it to spin, takes some power to turn it over on a cold morning up here in KY.

How clean are your battery terminals? Batteries should not be bad after two and half years.

I don't know about the Dodge trucks, but the Ford diesels have a lot of phantom draws on them. My batteries will hardly turn the truck over if I leave it for two months without putting a trickle charger on it.

That's not long but the heat is hard on them. Son just replaced his in a 2012 CTD 60,000 miles

Batteries should last longer. However, I have had some die sooner than others. Be sure you don't have a high amp constant draw.

Maybe not batteries. could be starter is starting to drag a little. diesel's have to turn over about 150 rpm speed to start. check out alternator to make sure it is putting out power also. 2013 model could have 2012 year batteries and some are 36 month so maybe they are toast but I would check out a few more things to make sure if you do install new batteries there is not something else draining them.

2005 Ram Cummins OEM batteries lasted ten years.

yes, heat is probably worse on batteries than cold (unless not charged good and then they can freeze in cold weather)

I would expect at least 5 years. Our 2004 duramax batteries went 11 years.
Our 97 Mercedes had the first battery replaced in 2010 (battery under back seat)
Our other 97 mercedes had the first battery replace in 2008(battery in trunk)
Our 95 S-10 battery lasted 9 years.

But we don't live in a real hot or humid climate nor have very cold winters.

Far cry from days of old when batteries didn't last more than a few years. Current batteries, at least for us seem to last a long time, well past the warranty.

The good news is most likely just one is bad. The bad news it that you should be replace both of them. Check on manufacturers warranty.

There is a recall of chaffing wires in the steering column.

There is a TSB that might effect your changing.
