Should your car shut off when you disconnect the battery?

No, your car should not shut off when you disconnect the battery. The battery provides power to the car's electrical system, but the engine is powered by gasoline. When you disconnect the battery, the electrical system will no longer work, but the engine will continue to run.

However, if your car has a computer-controlled engine, disconnecting the battery may cause the computer to lose its memory. This can cause the engine to run poorly or even stall. If you are going to disconnect the battery, it is important to first consult your car's owner's manual to see if there are any special instructions.
