Thanks for mentioning this. Just this morning I sent a support request to MHD to see if it's a known issue or if they have a fix for erased battery registrations. Last spring I flashed MHD stage 1 to my N54 and later noticed my battery registration was gone. Fortunately it was only a couple months old. There was an MHD update this summer and they suggest reflashing but I haven't, for this reason.

I heard back from MHD this morning and I quote directly after asking if flashing will erase battery registrations:
So was it a fluke that my battery registration was erased? Can anyone else verify this has happened to them?
no sir and MHD can not do that, we flash the DME, the battery registration is in other modules
