No, running it down one time will not ruin the battery. However each time you run an automobile battery down you shorten it's life. It is not designed to be totally discharged like a deep cycle battery. So there will be some damage.
If the battery were not securely fastened down Any speed could possibly crack the battery. If the battery is securely fastened down it would depend on where the vehicle was hit in the accident.
Running a cooling tray off the battery will put an additional load on the battery causing it to run down faster
A battery gauge "moves up and down" while running because of fluctuations in the voltage output of the circuit which it is connected to. This may be because of equipment on the circuit.
Disconnect the negative cable.
Dead cell in the battery requiring a replacement battery or something is on pulling power from the battery. Can be any light on the car or any relay.
Dead cell in battery, some light is on and is drawing power when the car is not running, or a relay is stuck. This is assuming the alternator is good.

Either the battery has a dead cell and needs replacing or something is on pulling power from the battery.
Because of the battery it heats up because it's working hard and the reason why it shuts down is so then it cools down because if it kept on running the battery would melt
