Know When and How to Replace Your Car Battery

A car battery is one of the important parts of your car because it supplies electricity to make the engine start and perform other electrical functions. Its lifetime is relatively short, which is between three to five years. If you are not attentive to its sign of failure, it might cause you to break down on the road at a really inconvenient time. This guide will help you know when to replace your car battery and how to do it yourself, making sure that your vehicle does not go faulty. 

Over time, car batteries deteriorate due to frequent short trips, bad weather conditions, and natural wear and tear. Recognizing the symptoms of a failing battery is not just a skill, it's a power that can save you from sudden inconveniences.

One of the earliest signs of a weak battery is a slow crank of the engine.

Another reason to believe that the battery of the vehicle is not charging properly can be observed if the time consumed by the engine to get started increases, or even if the cranking noise is dull.

Dim headlights or dimming dashboard lights are some signs of possible faults in the battery, although other electrical accessories such as power windows or the infotainment system may fail.

Another warning sign is the battery icon on your dashboard. This light doesn't always indicate a dead battery; it can also point to problems with the charging system.

However, it should prompt you to check the battery immediately. Additionally, if you need to jump start your car frequently or if the battery is older than three years, it's time to consider replacing it.

If you want to be proactive, check your car's battery for voltage with a multimeter. When the engine is off, the voltage for a good car battery should be 12.6 volts or more. A bad battery will likely have less than this voltage. Do this often, especially during a change of seasons, in order to diagnose problems as early as possible.

How to Change Your Car Battery

Changing a car battery is not complicated, and the right preparation and tools will provide you with the confidence in doing it. It does require that you take adequate safety precautions to avoid possible injury or damage to your car, but the process rests in your hands. 

Start by turning off your car and removing the keys from the ignition. This step prevents accidental electrical shorts. Wear gloves to protect your hands from battery acid and dirt. Locate the battery, which is usually under the hood, but may also be in the trunk or under a seat in some models. If you're unsure, refer to your owner's manual.

You'll have to disconnect the terminals of the battery. First disconnect the negative terminal that is usually marked with a minus (-). Then proceed to disconnect the positive terminal (+) as well. You may need to use a wrench for this, loosen the connectors and move them apart from the battery, being cautious not to touch any parts together.

Disconnect the terminals, and you can now take away the battery. Most batteries have their brackets or clamps screwed on, so be prepared to unscrew those, too. Take away car batteries with care as these are heavy and contain corrosive materials. Inspect your battery tray for any accumulation of dirt or corrosion and clean it well using either a wire brush or solution of baking soda.

Put the new battery in the tray, making sure it's facing the right direction. Attach the positive terminal first and then the negative terminal. Ensure the connectors are tight, and attach the clamps or brackets that will keep the battery in place. Then, before closing the hood, start the car and check that the new battery is working well.

Tips for Proper Battery Maintenance

If you take proper care of your battery, it will not need to be replaced as frequently. Inspect the terminals of the battery regularly for corrosion, which appears as a white or blue powder. Cleaning this buildup with a wire brush can improve the connection and lifespan of the battery. In doing so, you are ensuring the health of your battery and the reliability of your car.

Another factor that could impact battery performance is extreme temperatures. Parking in a garage or using an insulated battery blanket is often a good idea for cold temperatures. For hot weather, keep your battery clean and don't let the car sit unused for a long time.

Always dispose of old batteries responsibly when replacing a battery. Most auto parts stores and recycling centers accept used batteries, as there are materials in them that can even harm the environment when not disposed of correctly.
