How to Take Care of a Car Battery

1. Keep the battery clean

One of the easiest ways to ensure your car battery stays healthy is to keep it clean. This means regularly checking for corrosion on the terminals, which can be cleaned using a mixture of baking soda and water. Also, make sure the terminals are tight and secure.

2. Avoid extreme temperatures

Extreme temperatures can take a toll on your car battery’s health, so try to park in a garage or shaded area during extreme temperatures. If you live in a particularly hot or cold area, consider investing in a battery blanket or insulator to help regulate the temperature.

3. Keep your car battery charged

3. Keep your car battery charged

Another important aspect of taking care of your car battery is keeping it charged. Make sure your car is driven regularly, as leaving it parked for long periods without use can cause the battery to lose charge. If you’re not going to be using your car for an extended period, consider investing in a battery tender or trickle charger to keep the battery charged.

4. Check electrolyte levels

If your car battery isn’t a sealed unit, you’ll need to check the electrolyte levels every few months. This involves removing the caps on the battery and looking inside to see if the fluid levels are between the minimum and maximum marks. If they’re low, add distilled water to bring the levels back up.

5. Get regular battery check-ups

Finally, make sure to get your car battery checked regularly. Most auto parts stores offer free battery checks, which can help catch any problems before they become serious. Additionally, if your battery is more than three years old, consider getting it replaced to avoid any future issues.

  • Keep the battery clean.
  • Avoid extreme temperatures.
  • Keep your car battery charged.
  • Check electrolyte levels.
  • Get regular battery check-ups.

Check the Battery Regularly

Visual Inspection

One of the easiest ways to check your car battery is to perform a visual inspection. Look for any signs of damage or corrosion on the battery terminals and cables. If you see any buildup of white or greenish-blue powder on the terminals, this could be a sign of corrosion and may indicate a problem with the battery.

Additionally, check the battery casing for any cracks or leaks. If you notice any damage, it’s best to have the battery replaced.

Check the Voltage

Another way to check your car battery is to test its voltage. You can do this by using a voltmeter or a multi-meter. With the engine off and the key removed from the ignition, connect the positive and negative leads of the voltmeter to the corresponding terminals on the battery. A fully charged battery should read between 12.6 and 12.8 volts. If the reading is below 12.0 volts, the battery may need to be charged or replaced.

Test the Cranking Amps

Test the Cranking Amps

Lastly, you can test the cranking amps of your car battery. This will give you an indication of the current state of the battery’s overall health. To perform this test, you will need a load tester. Connect the load tester to the battery and follow the manufacturer’s instructions. The load tester will simulate the demands of starting your car and will give you a reading of the cranking amps. If the reading is below the battery’s rated cranking amps, the battery may need to be replaced.

  • Perform a visual inspection regularly to check for corrosion or damage.
  • Test the voltage of the battery with a voltmeter or multi-meter to ensure it’s within the appropriate range.
  • Test the cranking amps with a load tester to determine the battery’s overall health.

By checking your car battery regularly, you can ensure that it’s functioning properly and avoid unexpected breakdowns or malfunctions.

Clean the Battery Terminals

Why is it important?

The battery terminals connect the battery to the car’s electrical system and if they become corroded, it can inhibit the flow of electricity to the car. This can cause a range of issues, from difficulty starting the car to the complete failure of the battery.

How to clean them

How to clean them

Firstly, ensure that the car is turned off and the keys removed from the ignition. Then, use a wire brush to gently scrub away any buildup of corrosion around the terminals. If the corrosion is particularly stubborn, a mixture of baking soda and water can be used to create a paste to help dissolve it.

Next, use a mixture of water and baking soda to rinse away any residue from the terminals and dry them off with a clean cloth. Finally, reconnect the terminals and tighten them securely to avoid any future issues.

  • Make sure the battery is disconnected before attempting to clean the terminals to avoid any risk of electrical shock.
  • Wearing protective gloves and goggles is recommended when working with battery acid and cleaning solutions.

Regularly cleaning the battery terminals can help prolong the life of your car’s battery and prevent unnecessary breakdowns.

Keep the Battery Charged

Regular Usage

One of the ways to keep your car battery charged is by regularly using your vehicle. Cars that are left unused for long periods can cause the battery to lose its charge. Therefore, using your car for short drives or taking a road trip every now and then can help prolong the life of the battery.

Maintenance Check

You should check the battery, particularly during the hot and cold months, to ensure it’s not losing its charge. You can use a battery tester to check the voltage levels and condition of the battery. Also, clear the battery of any dirt or debris and clean the connections and terminals. Dirty connections can cause the battery to work harder than necessary, and this increases the likelihood of it losing its charge more quickly.

Charging the Battery

If you’re leaving the car unused for an extended period, consider charging it to prevent it from losing all its charge. You can use a battery charger to do this, but ensure the car engine is switched off and remove any electrical items from the car. Remember to follow the manufacturer’s instructions when charging the battery, as some require a specific type of charger, and overcharging could lead to damage.

  • Tip: Always wear protective gear, including gloves and eye goggles, while handling batteries as they are corrosive and contain acid.

Avoid Short Trips

Avoid Short Trips



Short trips can be problematic for car batteries, especially during colder weather. This is because the battery needs time to fully recharge after each use, and shorter trips may not give it enough time to do so.

Tips for Avoiding Short Trips

To keep your battery in good condition, try to avoid making unnecessary short trips. Here are some tips to help you do so:

  • Plan your trips ahead of time so you can group errands together and make fewer stops.
  • If possible, consider walking or biking for short trips instead of driving the car.
  • If you have multiple cars, use the one that will be most efficient for the task at hand. For example, if you’re just going to the store for a quick errand, use the car with better gas mileage so you don’t have to worry about the battery.
  • Consider carpooling or taking public transportation for longer trips, which will help reduce wear and tear on your battery.

Impact on Your Battery

The impact of short trips on your battery can be significant. When you only use your car for a short period of time, the battery may not have enough time to fully charge. Over time, this can cause the battery’s life to decrease, which can lead to a variety of problems including reduced power and a shorter battery life overall.


In order to keep your car battery in good shape, try to avoid making unnecessary short trips. By planning your trips ahead of time and using other transportation options when possible, you can help ensure that your battery is fully charged and ready to go when you need it.
