I went camping recently and had the Kona EV on the site for around 36 hours. Just before I went to leave, the 12V battery was dead and needed jumping to power up the car properly. The Aux Battery Saver+ was on all the time.
I did charge my phone 2 times or so with the car on semi-on mode, but I thought if the 12V got low, the battery saver would kick in.
When the power did come on, the dash smugly said that the battery was topped up by the Aux Battery Saver when the car was off.
Am I right in thinking that the 12V battery should never really die if this mode is on (obviously excepting a faulty 12V battery)? Any theories as to what happened here?
