Frequently Asked Questions
What is a car battery and what does it do?
A car battery is a rechargeable electrochemical storage device that provides the initial electrical power needed to start your car’s engine. It also powers all electrical components in your vehicle when the engine is off, such as lights, radio, and climate control. The battery stores chemical energy that is converted into electrical energy when needed.
How does a car battery work?
A car battery works through a chemical reaction involving lead plates immersed in a sulfuric acid solution. When the battery is connected to the starter motor, a chemical reaction occurs that releases electrons, creating an electrical current. This current flows through the starter motor, which cranks the engine to start. The battery then continues to provide power to the electrical system while the engine is running, and it recharges through the alternator.
Why should I change my car battery?
There are several signs that your car battery needs replacing, including slow engine cranking, dim headlights, a clicking sound when you turn the key, and the battery warning light on your dashboard illuminating. If you experience any of these issues, it’s best to get your battery checked by a mechanic. A failing battery can leave you stranded and also damage other electrical components in your vehicle.
How do I start changing my car battery?
Before you begin, make sure to disconnect the negative terminal first, followed by the positive terminal. Always wear safety glasses and gloves to protect yourself from acid spills. Locate the battery in your vehicle, usually in the engine compartment. Refer to your owner’s manual for specific instructions and safety precautions. Use a wrench to loosen the battery terminals, then carefully remove the battery from its hold-down clamp. Remember, the order is negative first, positive last, and reverse when reinstalling.
What if I accidentally touch the positive and negative terminals together?
Never touch the positive and negative terminals together while the battery is connected! Doing so can cause a short circuit, releasing a large burst of energy that can damage the battery, electrical system, or even cause an explosion. If you accidentally touch them, immediately disconnect the battery and inspect for any damage.
Which is better, a conventional lead-acid battery or an AGM battery?
AGM (Absorbent Glass Mat) batteries are generally considered better than conventional lead-acid batteries. They are more resistant to vibration and shock, have a longer lifespan, and can handle deep discharges better. However, AGM batteries are also more expensive. Lead-acid batteries are still a good option for many vehicles, especially if budget is a concern.
How much does it cost to change a car battery?
The cost of replacing a car battery can vary depending on the type of battery, the make and model of your vehicle, and the location of the service. A basic lead-acid battery can cost anywhere from $50 to $150, while an AGM battery can cost $150 to $300 or more. Labor costs can range from $50 to $150, depending on the complexity of the installation.
