Batteries - Diesel Trucks
I wanted to solicit a few opinions on batteries. My 2015 Ram is on it's original set of batteries, so about three and a half years of use and a little under 50,000 miles. I haven't had any failures ...

I bought a 2003 Ram 2500 5.9L HO CTD in Feburary of '18 I bought it from a flipper who got it from the original owner. It was low mileage, 86K and built in January '03. It still had the original Damiler-Chrysler labeled batteries in it. The "green eye" batteries made by Delco I think. While it hesitated slightly, it still started. Batteries were the first thing I changed. Shopped to see who had AGM's on sale and it was Bosch AGM's at Pep Boys, 25% off at the time. so two batteries and $300 later I was set. Working 15 year old batteries are rare, I normally expect about 6 years before they fail.
In the summer of 2017 I replaced the 7/11 dated Advance Gold group 49 battery in my '06 chassis Sprinter motorhome, as I expected it was near end of life and I was going on a long trip. I installed a Sears AGM because that was the sale at the time. Old battery is still good, sitting on the shop floor. (I traded in a totally dead junk battery that was sitting outside the shop)
Speaking of parasitic/vampire draw on batteries, the later Sprinters draw so much current when parked that they have a battery disconnect under the dash near the accelerator and generally if it is going to sit over a week, it is a good idea to disconnect it.
