Charging system Failure?

[jbeez]

In Forscan, do you see a spot for telling the PCM what type of battery it is?  On some vehicles, you can tell it an AGM battery is installed for example (like the MC ToughMax 65-850).

I do indeed have the toughmax 850 and wasn't aware it was an AGM battery. Found it in Forscan and the BMS reset seems to have detected that it is an AGM battery although the CCA is a bit off...

I thought the type of battery is programmed in with an IDS or forscan, not learned. I still stand by the notion of disabling the BMS so you stop beating batteries up

Good idea.  Although, AGM batteries charge differently than SLA batteries, so might actually be an advantage if the BMS is working correctly.  IDK.

I couldn't find anyplace in Forscan to set the battery type. The write capabilities on the BCM don't show that as a settable item.

I should point out that after the BMS reset I haven't had a reoccurrence of the issue so it may be solved...time will tell!
