I have relocated both batteries to the rear of the Jeep so I'm not worried about temps.
I usually see 13.9v - 14.2v on my scangauge and would like a bit more juice
EugeJK - I read your post, where is the connector that you unplugged?

In the early CRD days the system would overcharge the CRD's battery so the dealers apparently did a reflash of the TIPM to lower the charge voltage. So technically it is a programmable parameter. However..... the chances of getting a dealer to reverse this i'd guess is pretty low. In most cases they just reflash via a download and going backwards on revisions isn't something they do. Still you could ask..... but given the CRD's history of failed batteries I think they would say no.
IMHO just get a Dc to DC battery management system - at least its a known thing with no downsides except cost
