I have a Carly on the way currently, gonna use that to register the battery. Also a good friend of mine is an indy so if I decide not to use the Carly he can do the coding. I was reading about battery voltage, I didn’t realize that while a voltage of 12.2 will usually start the car it means the battery is ~77%. With the original battery pushing 7 years I’d rather change it now and forget about it. Plus with this battery shortage and living in Hawaii it might be a while if the stores go out of stock.
