I just replaced my batteries yesterday at 3 years and 2 weeks old. Started with the remote start not cranking because voltage was too low. Then continued to get worse and before I knew it, Jscan showed me that the charge % was down to 17% and over an hour highway drive commute for work, could not get the alternator to get it north of 22% with 14.5V tryin hard to. Auto parts store told me the battery was fine, and I mistakingly listened to them and drove it one more day, Jumping it multiple times over the course of 10 hours. Just replace them and do BOTH! Yeah it's 400$.... At least for an AGM 94R and the 48 dwarf battery that never gets used anyway, at least on mine.. S/S has never really worked since day one off my rig.. and do the 94R, it's 850CA versus the 650 of the OG unit, biggest one that will fit in there anyway. all issues gone, battery % back up to the top as it should be.

Where are you looking at charge % on JScan? I took a look but couldn't find it.

Go into -modules/powertrain module/ search battery and you will find all available battery data pulls for the computer. It is called battery charge %.. Hope that helps. I have really gone down the rabbit hole with the data available through the app having a hot/def consuming high egt monster that is the eco diesel trying to find the root cause. Let me know if you are seeking other info, I have learned most of what is available through that app.
