How Long Does the Original Car Battery Last?

[Zoey]

The original car battery can last 3 to 4 years. When the engine is not running, avoid sitting in the car listening to music for extended periods, and refrain from turning on the headlights or air conditioning, as these actions can shorten the battery's lifespan. In winter, try not to park the car outdoors overnight, as prolonged exposure to low temperatures can also affect the battery's longevity. A car battery is a type of storage battery, also known as an accumulator, which includes lead-acid batteries, nickel-iron batteries, and nickel-cadmium batteries. Its working principle involves converting chemical energy into electrical energy. The commonly referred-to car battery is the lead-acid battery, which primarily uses lead and its oxides as electrodes and a sulfuric acid solution as the electrolyte.
