What are the effects of a dead battery on a car?

A dead battery directly affects the car by making it unable to start, and the vehicle's anti-theft system will also fail to function properly. For the engine to start normally, it requires spark, gasoline, air, and the starter motor to turn the engine. If the battery is dead, there will be no electricity in the high-voltage coil, preventing the spark plugs from firing correctly. When the battery is dead, the fuel pump also cannot operate normally, which means fuel supply cannot be ensured, and the starter motor won't be able to turn the engine. When the car is not in use for an extended period, it is recommended to disconnect the negative terminal of the battery to avoid complete discharge. If the car is unused for a long time, you can drive it occasionally to allow the battery to recharge.
