I have no technical info to back this up but I personally think the two dissimilar batteries has a lot to do with ppl having battery issues, I don’t believe that’s the case every time but I think it adds to the problems we are having, as I have said before when I first got my JL in early 2018 the voltage would jump around from 12.8-14+ and I was told was normal and that was the “Smart Charging“ system working as designed but then 7 months into ownership I got the ESS not ready battery charging message and my voltage pretty much stayed at 14+ and after they tested it by doing a load test it failed and it was replaced under warranty.
After it was replaced it went back to the voltage going up and down but then as the months went by the voltage displayed kept creeping up but by this time I kept my JL on a battery tender a lot and also had ESS disabled with a SSS module so never really had a issue but that ESS motorcycle battery always bothered me and I have a winch and compressor that would tax the main battery on occasion so rather than fret over leaving me stranded I went to a dual battery system and my system seems happy at least for now.
Batteries are a consumable item and don’t last forever but batteries should be lasting more than a 2-3 years but then batteries are not made like they used to be where one could get 5-7 years
