As you know, the Model X is losing around 3% of battery per 24h of non use. I am debating what my best option will be when leaving town for about 17days this coming December. Should I charge the car up to 80-90%, and let it slowly discharge until I get back, 17 days later? (it shouldn't end up much below 50%). Or should I leave it plugged in, with a nighttime recharge set at, 50, 60, 70 or 80% during this whole time, so that the car never discharges more than those 3% below that set limit, per 24h period?
