The cluster focuses on concerns about 12V car batteries draining when vehicles are parked or off for long periods, including parasitic power draws, EV-specific behaviors, and hacky solutions like battery disconnect switches.

How does this not kill your car battery?
Maybe you could disconnect the battery cable every time you stop, and reconnect before you go?
Consider a battery failure while parked on a hill
Why can't the battery just be simply disconnected?
I'd be wary of draining the battery while the car is off. You don't want to prevent the car from starting
They're not using the car, so the battery isn't depleting.
I wonder what the power draw is? a tad worried my car wont start after longterm parking.
I wonder if installing a switch to disconnect the car's battery entirely would be an acceptable (but obviously hacky) solution.
I can only speak for the Leaf, but much like a petrol/gasoline car, the 12V battery is only charged when the car is on (and when the car is actively being charged). It is entirely possible to run down the 12V battery if you leave the car parked long enough without it being turned on. Once the 12V runs down far enough, you are no longer able to turn the car on (or charge it) as the 12V powers the contactors for the main battery. I have had to jump start my Leaf due to a bad 12V battery.
What if the thieves remove the battery because they're parting out the car?
