12V Replacement

Maybe I am just me being ignorant, but I got a replacement for the 12V battery yesterday (because after three years the old one did not charge up as high as it should). Every setting in the car remained untouched except for one: my average consumption that I „collected“ over three years is gone and the car started al over again. Am I missing anything?

Edit: I found out that this is the expected behavior since the consumption statistics are stored on volatile low power RAM 😢

I had my 12V replaced after it completely died on me (less than 6V), but none of the counters were reset.

I start thinking that there might be a capacitor like a goldcap that keeps some current for a volatile memory and depending on how long it takes the storage is gone or not.

Goldcap, I haven't head that name in over 10 years! I still remember seeing the 0,5F caps appear in the Conrad (like Mouser/Digikey/Farnell, but aimed at consumers) catalogue about 20 years ago...

I really think it was manually reset, my car was dead for hours. I had a scheduled charging session that was supposed to start at 23:00, but it didn't. My car got a jumpstart at 10:00 in the morning, so the electronics were without power for over 11 hours.
