do you have any “data logger” device in your arsenal or any multimeter that records voltage over hours (you can make one with an arduino and an sd card shield) or at least a very long wire that goes from the car to where you spend most of your time inside to keep an eye? you can use the security camera app in an old phone or a baby monitoring camera and keep the Ammeter under the hood as long as you can monitor every 20 mins or so. When you leave the car, it does not go to “sleep” instantly, but after a few minutes. In addition to that, without a continuously connected trickle charger (or one of those little solar ones that you leave on the dash), batteries do discharge at a few milliamps all the time
