Ours has been parked for a few months thanks to covid and our displayed range has dropped from 81 miles to 67 miles. How can I check the max battery capacity?
If you have literally not driven your i3 in a few months, its 12 V battery might be so discharged that it would not boot the controllers necessary to enter drive readiness state. Unlocking then locking the doors either in person or remotely would fire up the DC-DC converter to charge the 12 V battery for at least 30 minutes. I do this at least weekly to prevent the 12 V battery from discharging too much. Leaving an EVSE plugged in won't charge the 12 V battery after the battery pack has reached full charge.
The Batt. Kapa. max value in the hidden service menu is a calculation of the usable battery pack capacity. However, the calculation can vary quite a bit, so it's not as accurate as measuring the energy produced during a slow discharge from full to empty or the energy required to fully charge the battery pack from empty. Search for how to access the hidden service menu.
