The car battery is one of the most critical components of your vehicle’s electrical system, providing power to start the engine, operate the accessories, and keep your car running smoothly. A faulty or old battery can cause a range of problems, from difficulty starting the car to complete system failure. Therefore, it is essential to know how to tell if your car battery needs replacing.
