Battery Replacement using Memory Saver?

[RangerRider88]

There has been a lot of battery questions and comments on this forum, but I wasn't able to search and find one regarding a battery replacement using a 12V memory saver via the OBD or lighter receptacle (which would require the key switch to stay on during a replacement?). I've done this successfully with other vehicles, but don't know how finicky the Ranger monitoring system is, or if the BMS would require a reset anyway with a new battery. Anyone tried this successfully? Thanks for your comments.

I have the OBD saver plug it , but decided not to use it just to see what if anything would happen if I didn't. I changed out my battery after having the new one on charge for about 2 hours first before installing it to make sure the BMS would have a fresh point to start on . I didn't lose anything on my radio settings or anything else that I remember. Just don't take all day to swap it out and I would think everything will be good .

dealer recently replaced my battery and I inquired about a bms reset.

they said it wasn’t necessary

didn‘t lose radio stations, but I did have to scroll through and “reset” my dash display screen settings

Check if your auto up & down driver's window still works. And the safety reversal for the window. It has to be reset after battery disconnect.
