how would that be possible? some magic switch flips at day 61?

Just took mine out of storage, after 1.5 months I dropped about .15 ahr not as cold as wether but still cold I had mine at 80% almost the whole time.

Note: my 12 volt died half way through as I forgot to remove my OBD dongle.

that would be weird. I always thought about removing my dongle but failed to do so every time including a 22 day stretch

1.5 months > 22 days :roll:

only takes a bit over a week. your LEAFs 12 volt management system isn't keeping up plus most who had left their dongle powered up had their battery die in a few days. didn't take weeks. this is why you should always disconnect the device before powering down. some have installed an on/off switch. this is probably more than is needed

New cars stay on dealer parking lots for much longer, and then we buy them and start to stress about battery degradation. :lol: :lol: Some of these cars are there with charges ranging from full to almost empty. The battery is not a gallon of milk, so have fun

Here we go again. What is the load after an hour of sleep with dongle plugged in and no BT devices nearby. Have you measured it?
