Hi,
I recently changed the battery myself on my 2007 335xi but now I have some concerns because it looks like the new battery isn't fully charging.
Basically, it's been measuring about 12.1-12.2 with my voltmeter since the last two weeks when I did the change. And I charged the battery with an external charger overnight (the day of the replacement) and I've been driving the car a lot.
My orginal battery was 90Ah and the new one is 80Ah. I'm pretty sure I did everything correctly (code new battery capacity, register new battery).
Here are some screenshots from INPA. Does anybody know what all these numbers mean and how come some of them are zero?

PM field 1

What is "chargerange hours xx - yy" ?
PM field 2
----------
What is "% actual charge status" and "% charge status 1 day ago" and why isn't is close to 100%
What is "% actual start capacity" and "% start capacity 1/2/3/4/5 day ago"?
Although I googled SOC (State-Of-Charge), I'm not sure what "Ah Q SOC" or "SOC-fit" mean.
I also googled SOH (State-of-Health) and I would expect it to be close to 100, so I wonder why it is at 0.
