To say that batteries, starters, and alternators are important engine components would be an understatement. In fact, without them, it would be impossible to maintain the electrical system in your vehicle, and it wouldn’t be able to turn over when you turn the key. Keeping your starting and charging system in top shape is critical to ensuring the reliability of the vehicle you drive every day, so you don’t find yourself stuck with a dead battery, a bad starter, or a faulty alternator.
