- The engine will stop running. This is because the battery provides the electrical power that is needed to start the engine and keep it running.
- The car will not be able to move. This is because the battery also provides the power that is needed to operate the transmission and other components that are necessary for movement.
- The security system will be disabled. This means that your car will be more vulnerable to theft.

It is important to note that disconnecting the battery can also cause some problems. For example, if you disconnect the battery while the engine is running, it can damage the alternator. Additionally, disconnecting the battery can erase the data stored in your car's computer.
For these reasons, it is important to only disconnect the battery when necessary. If you are not sure whether or not it is necessary to disconnect the battery, you should consult with a qualified mechanic.
