7 Ways to Maintain Your Car Battery for Longer Life and Durability

Taking care of your car’s battery is essential for ensuring the performance and reliability of your vehicle. Many people may consider the battery as a part rarely requiring special attention. Still, in reality, it’s the main power source that supports the entire electrical system of the car. Therefore, properly maintaining your battery is crucial to always keeping your vehicle dependable. To learn how, see the full article below!

How to Maintain Your Car Battery

So, how can you maintain your car battery to keep it lasting longer? Here are some steps you can take to keep your battery in top condition:

1. Regularly Check Battery Voltage

Checking the battery voltage is a very important first step. You can use a voltmeter to ensure the battery voltage is normal. A good car battery should have a voltage range between 12.5V and 12.9V. If the voltage drops below 12 volts, the battery will likely start to lose power and require attention.

Ideally, the battery should be checked once a month to monitor its health. If you’re unsure or don’t have the equipment, you can ask a technician at a nearby garage for help.

2. Ensure Clean Battery Terminals

Dirty or corroded battery terminals can hinder electrical flow. Dirt or corrosion on the terminals can cut off the power flow from the battery to the engine, making it difficult to start the car. Therefore, it’s important to clean the battery terminals regularly. Use a small wire brush and a specialised cleaning solution to remove corrosion.

Once cleaned, ensure the cable connections to the battery terminals are tightly secured. Loose connections can cause electrical flow disruptions even if the battery is fully charged.

3. Regularly Check Battery Fluid

If your car uses a wet battery, regularly check the fluid level. Battery fluid should be within the maximum and minimum levels marked on the battery casing. Top the liquid level with distilled water to the recommended level if it drops. Avoid regular water, as it can damage the battery’s internal components.

4. Keep the Car in Use

One reason batteries drain quickly is infrequent vehicle use. When the car is rarely driven, the battery’s charge gradually diminishes. To prevent this, try to start your car’s engine at least once a week, even if you don’t plan on driving it.

Let the engine run for a few minutes to recharge the battery and maintain the vehicle’s electrical circulation. If you plan to leave your car unused for an extended period, consider disconnecting the battery cables to avoid unnecessary power drainage.

5. Avoid Excessive Use of Accessories When the Engine is Off

Many people habitually use accessories like radios, lights, or phone chargers when the engine is off, which can quickly deplete the battery. Try to avoid using electronic devices when the engine isn’t running. If you want to listen to music or use the air conditioner, ensure the engine is on so power is drawn from the alternator, not the battery. It will help prolong the battery’s life.

6. Pay Attention to Battery Age

Car batteries are not designed to last forever. Typically, a battery’s lifespan ranges from 2 to 5 years, depending on its quality and maintenance. After this period, the battery will start to lose power significantly.

If your battery is ageing, check its condition frequently and budget for a replacement. Replacing the battery before it fails completely can help you avoid emergencies, such as the car breaking down on the road.

7. Use the Correct Battery

Choosing the right battery for your vehicle is essential. Every car has different power requirements, depending on its engine capacity and the number of electronic devices it contains. Use a battery with the size and capacity recommended by your car’s manufacturer. If unsure, consult a technician or refer to your vehicle’s manual.

Signs Your Car Battery Needs Replacing

Even if your battery maintenance is excellent, there comes a time when replacement is necessary. Here are a few signs that your car battery may be reaching the end of its lifespan:

1. Difficulty Starting the Car

One of the most common signs of a weak battery is difficulty starting the car. If you need to try several times to start the engine or if the starter sounds weak, it’s likely that the battery is losing power. If this happens, check your battery in the garage immediately.

2. Dimming Vehicle Lights

A battery that can no longer hold a charge effectively may cause the vehicle lights to dim. Dimming lights indicate that the battery’s power is becoming unstable. To avoid further issues, replace it promptly to prevent breakdowns, particularly at night.

3. Acidic or Unusual Smell from the Battery

If you notice an acidic or unusual smell around the battery, it could indicate a leak of the electrolyte fluid. A leaking battery fluid is harmful to the battery and can also damage nearby components, such as cables or the car body. If you detect an unusual smell, inspect your battery and replace it if necessary.

4. Corrosion on the Battery Terminals

Rust or white residue on the battery terminals is a sign of corrosion. While it can be cleaned, if corrosion continues to appear, it’s a sign that the battery is weakening. If left unchecked, it can disrupt the flow of electricity, making it hard to start the car.

5. Battery Indicator on the Dashboard

Nearly all modern vehicles are equipped with a battery indicator on the dashboard. If this light comes on, there’s an issue with the charging system, possibly due to a weakening battery or a problem with the alternator. Don’t ignore this warning, and have your car checked at a garage.

There are various ways to maintain your car battery to ensure its durability. Regular maintenance extends the battery’s life and guarantees comfort and safety while driving.

A healthy battery ensures your car can be used whenever needed without worrying about a breakdown. This care also helps maintain the performance of the entire electrical system, including lights, cooling systems, and audio.
