re: Car died while driving issue

Your battery is used to start the car. If the car is running and died it is usually not the battery as the battery does not keep the car running. Alternator, running out of gas, or a fuel injector issue would be more likely culprits. When you try and jump the car back on if the AC coming out does not get cold then likely alternator, as it is needed to run AC compressor.

That is not true anymore. It has not been true for years. Modern cars (the last 20-25 years) use battery voltage to run the computer systems. If battery voltages drops too far below 12 volts the car will shut down.
