What is a flat car battery

A flat car battery is a common problem that car owners face from time to time. It is also known as a dead battery or discharge battery. As the name implies, the battery has no charge and cannot power the car’s electrical system or start the engine.

Car batteries rely on a chemical reaction between lead and acid to produce electricity. Over time, the chemicals break down, reducing the battery’s performance and lifespan. Excessive use of electronics like lights, radio, and air conditioning can also reduce the battery’s charge. Other factors like extreme temperatures, incorrect installation, and a faulty alternator can contribute to battery drain and a flat battery.
