Prior to that, it had been on a BatteryMINDer 12116 for six months last year. No issues last year. Been using either one - mostly the OBC-20A - whenever it's in my garage.

Diesel models probably charge the battery differently I would imagine.

Quite possible.

Seems like a pretty dumb Intelligent Battery Sensor if overcharging is occurring.

Maybe not. I think the goal of this was more epa/mpg cheating. Just like the stupid cutting the motor off at a stop. Just a way to cheat the mpg numbers.


With a diesel they don't have the same "need" to cheat I would imagine. Plus if you don't keep a diesels battery fully charged your going to get cranking problems and pissed off customers.


To risky to try the cheat on those.


Again all guessing but I could see this playing out that way.


Volt meter will tell you right quick. It loves to stop charging while driving. If you never see it dip under 13.8 or something then the diesel isn't doing the no charging stuff.
