Mine lasted 12 years. As some on here say: they last until they don't. Maybe carry a set of good jumper cables. I could tell by the dash voltage gauge that it was taking longer for the needle to reach the point that it had for years.

Living i the Central Valley of Ca, you are right on the cusp of replacement time. Extreme heat is the killer of batteries. Carrying a single jump pack won't help with w diesel. Only you can decide what to do. I usually wait until they die, then find out right when I am getting ready to go somewhere. Then I have to tell the DW it'll be an hour....I have to go to Costco to replace the batteries again.

OP, as you see by the responses, battery life can vary from a few years to over 10.
Guess what that makes the average?
You’re getting into the average.
On a scale of good to worst conditions (all other things equal) it goes moderate temps = longest battery life. Cold conditions = not as good. Hot weather = shortest life.

You’ve asked a crystal ball question that is frankly pretty silly. Given you have a high $ truck that is a garage queen, I’ll presume you’re an older person. As such you probably have your own years of experience with car batteries and this vehicle or it’s batteries are not any more special than any others.
So bottom line, flip a coin.

Hi salem,

Where you live makes a huge difference. Cold storage is best so long as the batteries are fully charged before hand.

Heat kills batteries fast.

My car is from 2013 and the battery is just fine. It will start the car at -27 c, with no block heater. It will NOT start the car at -34 c, with no block heater.

My vote is do a load test. Most battery places will do such a test for free.

To do so the batteries need to be separated.

No, you should let them go bad. Yes, that's a bit of sarcasm. Of course replace at 4-5 years or so. Like said, they don't give much warning.

with two completely dead batteries on my duramax, and temps of about 50F, I dug out my costco jump start from under the back seat, plugged it on, took about 5 seconds for the glow plug light to go out, hit the ignition, cranked slow but started up quickly. Yes, a decent jump start unit is capable of starting a diesel in moderate temps. pretty much drains it the first time, but can be done.

In Feb of 2018 I bought a 2003 RAM 2500 that was built in January of '03. 86K original miles. It had a little hesitation but cranked up fine. The batteries were made in Dec of '02, they were the original Damiler Chrysler batteries, and upon close inspection they were the Delco/Delphi batteries with the "green eye" on the top but it was covered up by the Damiler Chrysler labels.

These batteries had lasted 15 years, which shocked me. I have in the past used the Delco/Delphi batteries due to their long life and got as much as 9 years from one, but the quality on the newer ones wasn't as good and I gave up chasing down a dealer to buy a battery that didn't last.

I wanted AGM and shopped price, Pep Boys had a 25% off sale on the Bosch AGM's so that is what I got.

As already noted, nowdays batteries work till they don't. You get about one or two strange startups that leave you going "what happened" and then they are toast.

Traveling, your best bet is to have a small lithium jump start pack and when they croak, if you are away from home, jump it and head for the nearest auto parts store and buy two new batteries.
