When it has gone to sleep my 2L V6 petrol draws 16mA with higher pulses of current corresponding to the red flashing alarm LED. I connected the ammeter using some long test leads so I could close all the doors, the boot and the bonnet to ensure it was fully asleep. I didn't observe the ammeter as the various systems went to sleep so I don't know how long it took to drop to 16mA. I think I returned to it after an hour.
During covid lock down when car wasn't getting much use I used a solar panel from Halfords plugged into the cigarette lighter socket. It saved me from having to use an extension lead and battery charger. Some 75 cigarette lighter sockets remain on all the time and some switch off when the electronic modules go to sleep.
