Battery drainage while parked for a while… any solution?

That's ok if you park it at home, but like DaveB, if you leave it at the airport carpark for more than a few weeks, it's a bit of a lottery if the car will have enough charge to start when you get back.

My car has been completely dead in the past (after sitting for about 3 weeks), so now, if it's sitting for more than a week, I disconnect the second battery, fully charge it and take jumper leads.

It's dissapointing that the second battery is now a backup crank battery, We have to take a THIRD battery when we go camping, We are often remote where there isn't phone or radio contact, so I just can't risk being stranded in the middle of nowhere with a dead car.

Starlink is your friend. We were at a remote canyon campsite. No cell signal. Used starlink and viber to call rental office because someone else was occupying our site when we got there.
