Can a Car Battery Die if the Engine is Running?

Yes, a car battery can die even if the engine is running.

There are a few reasons why this can happen:

• The alternator is not working properly.
  The alternator is responsible for charging the battery while the engine is running. If the alternator is not working properly, it will not be able to provide enough power to the battery, and the battery will eventually die.
• There is a drain on the battery.
  If there is a drain on the battery, such as a faulty light or accessory, the battery will not be able to store enough power to keep the engine running. Eventually, the battery will die.
• The battery is old or damaged.
  Even if the alternator is working properly and there is no drain on the battery, the battery can still die if it is old or damaged. Batteries have a limited lifespan, and they will eventually need to be replaced.

You can check the alternator by using a multimeter to measure the voltage output.
• Check for a drain on the battery.
