No, the HV was sitting at 43% when I parked it but everything was dead in the morning, so I don't know how much trying to charge the 12V would have drained it before it finally fell over. Not much I can do about it anyway.alohart wrote: ↑Sun Apr 04, 2021 11:12 pmThe HV battery's charge level shouldn't drop more than 1%/month while your i3 is parked. 12 V is required to close the HV battery's main contactor, so without 12 V, the HV battery is isolated and would only self-discharge.
Of course, if its charge was < 10% when your 12 V battery failed, it would be good to install a replacement 12 V battery ASAP.
