I wonder how long a Cybertruck Battery (ies) will stay charged when the vehicle has not been driven for a while and has not been plugged into to a power source?

Since we don't know what type of battery it is.. how large it is.. or what the idle load on it is.. i don't think we can answer that for the CT

One would need a Cybertruck (and probably data from thousands of them) to answer that question, but if you turn off climate and sentry mode as we did a couple weeks ago with our Model Y when we were out of state, we were losing a mile every other day.

you might as well ask how many angels can dance on the head of a pin. if you haven't noticed, no one knows what battery the CT will have.

current teslas lose minimal charge if sentry mode is off, if sentry mode is on then a few % points per day....CT results could vary give so many unknowns.

If you Power the CT off like we do now, it should be fine for long time. No ghost drain if it's totally turned off.

Teslas are never "off" but asleep. There are power-consuming features such as Cabin Overheat Protection and Sentry Mode that will consume more, but most (all?) of these are disabled when the pack reaches 20%.

When the pack hits 0%, then everything is shut off and it will not drive (or even poweron) until charged. It will probably need to be "jumped" to initiate charging at this point.

Note that 0% is NOT zero volts, but merely "not enough voltage to be useful". If the pack ever drops to zero volts, then it's irreparably damaged and must be replaced. I've heard of people getting to 0% but not to zero volts, so I think you'd need to neglect your car for months or years to reach that point.

If everything is turned off, a charged 300+ mile battery should go over a year but it's temperature dependent. Too cold or too hot will shorten the time.

If you turn on Sentry Mode it might only make it 3 months before the battery needs charging again. If you turn on Cabin Overheat Protection, it depends upon how hot it is and whether it's parked in the sun or not, but there are two modes:

Fan Only (this mode simply vents the cabin gently to prevent solar heat gain from building up too much)

A/C (this mode will run the A/C to maintain safe temperatures in the cabin)

Fan only mode uses very little power while the A/C mode uses quite a bit more and it's impossible to say how much current they use because it depends upon the temperature and how much solar gain there is.

Sentry mode, like Overheat Protection, will vary by number of events, too.

Yep. And IRCC, when we left our Model 3 at the airport in June a few years ago and did not think to turn those off, the daily drain was something like ~15 miles per day. So it will vary by climate and personal circumstances. Your Mileage May Vary!
