How To Check Car Battery

The mechanisms of a car are known to be incredibly challenging and intimidating. That’s why many people are afraid to pick up their car hoods and start exploring the car’s engine. Testing your car battery and understanding your model engine are essential parts of owning a car. The car battery is one of the most crucial elements to ensure your vehicle is running efficiently. For this reason, constantly checking that this device is in good order is an advantageous practice. We have compiled this guide to help highlight the processes and make it less daunting and more straightforward. Here is how you can effectively check your battery from the comfort of your home:

Keep in mind that no vehicle battery is the same, although these batteries are mainly made the same way in regard to electrical maintenance and other factors. This guide is helpful for all car batteries. However, there may be specialized circumstances that differ from the normal wear and tear of car batteries. For this reason, please contact us to search and find more information if you have questions after reading. We are highly knowledgeable and qualified and can install a new battery, charge the battery, or repair your existing vehicle battery at our store, which has been around for years.

Conducting Testing Under The Right Parameters Is Key

A great opportunity that most car owners fail to take advantage of is receiving free battery testing. Many of these auto parts shops offer a free battery installation when you purchase a new car battery.

Nonetheless, there are other options if your local store doesn’t offer free testing, and there are other ways to test a car battery safely.

As previously mentioned, testing your battery is essential. Doing these testings can help avoid having to jump-start your car at times that are inconvenient to you or can aid in your battery not dying when you’re out and about. It’s highly recommended to test a car battery twice every year to help you avoid the possibility of your auto battery failing from a lack of car maintenance and upkeep.

What Preparations Need To Be Done Before Testing Is Conducted? 

Before testing the car, you need to complete a variety of crucial preparation tasks. You need to start by turning your car off. In addition to doing this, you need to turn off any other electronics. These devices may use battery power even when the ignition isn’t switched on.

You then need to proceed with the preparation process by switching your ignition off. It is also good to note that it’s excellent practice to disconnect your ignition system temporarily. This is done by removing your fuel pump fuse or relay. Otherwise, you can simply uncouple the ignition coil. The uncoupling ignition coil step only applies to a car equipped with plug wires, a distributor, and a coil. So, you should make sure cars you are working on that these.

How To Check For Your Car Having ‘Dead’ Battery Terminals: 

Knowing how to test a car is a vital skill. However, the problem may lie with the terminals of a battery if you think that you’re dealing with a seemingly dead battery. Therefore, being able to analyze the battery terminals is also an excellent skill to have. To inspect if your car has ‘dead’ battery terminals, search for a multimeter, and begin by turning the car off and feeding your multimeter’s red probe to the battery’s positive terminal. Follow this by connecting the black probe to the terminal with the same connecting cable.

The next step is to conduct cranking amps. Ask someone to crank up the car’s engine. When your car’s engine has been cranked, and your multimeter registers more than .5 volts, it’s a brilliant indicator that you should more than likely replace the cable connected to the battery of the car or clean the clamps.

After you have done this, repeat the process with the alternative battery terminal. However, this time, you must switch the probes and connect the black probe to the battery terminal. An indicator that you may have bad corrosion is if you see powdery greenish-white or fluffy deposits around the terminals. This corrosion is built up to such a point that it is preventing the car battery from delivering or receiving a charge.

How To Test a Car Battery With a Multimeter:

Using a multimeter to test a car battery might seem like a daunting way to test a car. However, using this device and testing your battery with a multimeter is incredibly helpful. Start by removing the positive terminal cover of the battery then use a wire brush to clean the terminal to remove any corrosion.

The next step in this process to test the battery with a multimeter is to set your voltmeter to the lowest possible voltage setting above a setting of 15 volts. Connect the negative lead to the battery’s negative terminal. Follow this by connecting the red lead to the battery’s positive terminal.

After testing your battery with a multimeter, all you are required to do is to be informed of what voltage to expect from your battery. You can contact us if you have any problems or questions about the make model and the battery test.

How To Test A Car Battery With Power Probes: 

This is yet another simple process to test a car battery. Connecting the power probes to test your battery ensures that you aren’t required to change any settings that you need to adjust when making use of a multimeter.

The beginning process follows the same as when you test your battery with a multimeter. After this is done, the power probe should provide you with the relative information and show whether your battery, the electrical system, and the charging system is in good condition or not.

How Many Volts Should All Cars Batteries Carry?

The value you search for when reading the multimeter at home can vary. The voltage reading you get should be between 12 – 4 to 12 – 6 volts. This depends on whether the battery is on charge or not. Any voltage lower than 12 – 2 volts and any voltage higher than 12 – 9 volts indicates that your battery needs a slow charge or excess charge removal.

You can remove the charge by temporarily connecting the high beams, as you may find that this helps better the maintenance and reduces the need to get a repair on the battery. However, the exception of this involves an alternator. This applies to when the alternator is charging the battery. You are likely to find a voltage of approximately 14 – 5 V. Using this alternator is the only time when the voltage should be lower.
