I’m coming up on 3 years with my original battery in my 22. I get the deep sleep notification maybe once or month or so. Mainly just when I leave my dash cam running overnight and it’s monitoring mode. My auto start stop hasn’t worked in over a year. I know my battery is not at its full capacity, but outside of that occasional deep sleep notification, I never have any issues.
I just had it in the dealer a week ago and they did a warranty test on it and everything checked out. I wonder if I should try resetting the BMS. Is there any reason to not do that on a older battery?
