+2 on the quick disconnect switch.
I don't see where you responded to this suggestion. This $12 part will save your $500 deposit and eliminate any concerns with parking anywhere long term.
Top Post Battery Master Disconnect Switch
I have used similar device on vehicle I left sitting idle for six months at a stretch when I was working on assignments in other states. As far as on a daily basis, the biggest pain is opening the hood to disconnect.
Until there is some indication that Toyota has figured out the problem, you can always use a battery tender. I use one on a semi-weekly driver just to make sure the electronic don't drain the battery significantly.
When you use the quick connect, eventually the ECU will discharge. So you after reconnecting, you need to be aware that most modern cars will need to be driven at least 30 miles before you can have them inspected. In Texas, they use information from the ECU to gather information about your emissions. The 30 miles is necessary for the ECU to register information they need for inspection.
I have had a similar battery issue develop with my 2018 RAV4 hybrid. It gets driven only 4-5 times per month right now and we had two recent occurrences of the dead battery after just 7-8 days of sitting in the garage. The Toyota dealership looked into it and could not find anything wrong but replaced the battery anyway under the warranty. The service manager did not seem to think this is a specific RAV4 issue and that these new models just need to be driven every couple of days to keep the battery charged.
About the quick disconnects and cheap jumpers: the 2018 RAV4 hybrid has battery in the back of the vehicle under trunk floor and trunk door lock does not operate without power. I can crawl into the trunk from inside the car, but the trunk door needs to be open for me to open up the floor board to gain access to the battery. The trunk door lock can be opened from inside with a screw driver, which took me about half an hour and several viewings of an Youtube video demonstrating it. Not exactly an exercise I want to do at an airport parking lot after coming back from a 24+ hour travel from Asia or Antarctica. If other RAV4's have similar genius design I think the disconnect switch as well as <$100 jumpers are pretty much a dead idea. The car has jump sites under the hood but they are about 3' apart so I ended up buying a $200 "professional" briefcase jumper to get one with long enough clamp cables to reach the RAV4 jump contacts under the hood.
