You put a $1 chip directly on the battery itself that if it ever drops below "x" volts, it breaks the circuit. Even if the owner has to take it back to the dealer to get it "reset" at least the battery will be saved.
My $500 LiFePo4 battery for my bicycle has something like this to prevent cell reversal. They can certainly do it for a car unless they are just doing it on purpose.
A disconnected lithium based battery can hold a base charge for YEARS.
