What Are the Effects of a Dead Car Battery?

[DiMarley]

A dead car battery directly impacts the vehicle's ability to start, and the car'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. Additionally, the fuel pump won't operate, cutting off fuel supply, and the starter motor won't turn, making it impossible to start the engine. A car battery, also known as a storage battery, is a type of battery that converts chemical energy into electrical energy. Car batteries are categorized into conventional lead-acid batteries, dry-charged batteries, and maintenance-free batteries. Typically, when people refer to a car battery, they mean a lead-acid battery. The normal lifespan of a car battery ranges from 1 to 8 years, depending largely on the vehicle's condition.
