If I left the model X on the street how many miles would I loose a day by not driving it?
After 365 days approximately my fully charged 18650 lithium ion flashlight cell was down to 3.4 volts from the full charge 4.2v.
No usage the first 6 months, thereafter very limited usage. So left alone these cells are certainly good for at least a year.
A 'survival mode' option would be nice to have available which would disconnect cells, strings, bricks and modules at the lowest
level possible preparing for a near future of complete neglect. Sure the 12 volt battery would die first but the lithium ion cells
could hold on for possibly a year or two.
It does depend on your settings of "always on" and a few other things. Between 4 miles to 10 miles per day seems common. The losses are due to "vampire" drains from the electronics not being totally off, not from the battery self discharging.
The title should perhaps say, 'charge decay (or loss)' and not 'battery decay' which is different
