Car Battery Test-Battery Performance, Frequency And Checking

Is your battery fully charged or not? Is your battery performance good or bad? The only way to know everything about your battery performance is by testing. The battery is the lifeline of your car as it is going to power entire electrical components of it. Your car will not even get started if there exists a battery malfunction.?

However, whenever it comes to test the performance of your car battery, then the most common questions that can come to your mind are what care battery performance has to be tested? How to check your car battery health or how often you need to perform battery testing? Whatever question regarding car’s battery testing, you can find your answer here.?

What car battery performance needs to be tested?

Do you want to avoid any kind of unwanted repair bills or unexpected breakdowns? Then, it is highly important to keep checking the condition and health of the battery of your car. As batteries are highly susceptible to failure, therefore, you must know what car battery performance aspects you need to consider to be tested.?

Signs to Consider

• Dim headlights when car is idle?

• Change in sound when your car is idle
  

• Struggling start motor when switching on the ignition
  

It is not easy to tell when your battery is falling. However, checking it regularly can save you from problems and will let you avoid them effectively.?

Things to Check in Your Battery Test

Here we have some of the important aspects to test to ensure your battery performance:

Check voltage and electrolyte level?

For an effective battery performance test, it is important to check its voltage and electrolyte levels. Checking these levels will help you to spot any problem in your car’s battery with ease. Both of these aspects of battery are pretty simple to test and effective too to let you know about the battery performance.?

Check battery clamps, cables and terminals

Check for any grime buildup on the clamps, cables and terminals of your battery. It is because these can lead your battery to poor performance. Therefore, it is always important to clean and maintain them to ensure effective performance of your car battery in the best possible way.?

Check your battery for cracks

Having a look at the physical performance of the battery is important to see if there are any cracks. For this, disconnect your battery terminals and place it on any flat surface and make sure no bulge is formed on the battery surface. Also, check terminals, if there is any crack on them, make sure to change them.?

How often do you need to check your car battery?

As car battery is important therefore, it is also important to know how often you need to check your car’s battery to keep it well-maintained. Most manufacturers recommend testing your car’s battery at least twice a year.?

If you are living in a cold area then it is always better for you to test your battery in late spring and late fall. Because extreme cold and hot weathers are some of the most common things that can wear your car battery down.?

• Hot weather can lead your battery acid to evaporate faster, which can lower the amount of acid in the batter, eventually. This will cause it from taking full charge as well as from producing much power that is required for your vehicle. Also, it can lead to battery corrosion on your cables and posts.

• On the other hand, cold weather can make your battery work harder to start your car’s engine and can slow down the chemical reactions in your battery and will lead to voltage loss. Lower battery voltage can freeze your battery when in low temperatures.
  

Therefore, a thorough battery test is important to consider in late spring and fall every year to keep your battery up even during extreme weather conditions too.?

Normally a car battery has the ability to last for up to 4.5 years, and replacing your battery after 4 to 5 years can be a good idea to consider too. However, between these years, you must keep checking your car battery to ensure its better health and performance in the best possible way.?

How do you check your car battery health?

Here are the ways you can test your battery health like a pro:

Headlight Test?

To identify if there is a battery problem or not, headlight test can be the easiest and quickest way to consider. For this, you just have to start your car with headlights turned on and identify if these are normal. Now rev your engine, if headlights are at the same brightness, your battery is fine probably.

However, if these are dim, then the alternator is not producing enough charging and they are running your battery off.?

Use a Multimeter to Test Your Battery?

Using a multimeter can be another way to test your car battery. A multimeter can be found easily at any hardware store and can be a better tool to keep in your car.?

• Set voltmeter on the multimeter at 20V DC.

• Touch the positive probe with a positive or red battery terminal and the black one with the black terminal of the battery.
  

• Turn your headlights on to provide your battery with a light load
  

• Check the charge of your battery.
  

• If the battery is constantly at charge less than 80%, this can lead to acid stratification. It means electrolytes have been collected at the battery's bottom and making the battery's upper half acid-poor.
  

Find out ways to avoid acid stratification because it can reduce battery performance and can lead it to fail.?

Final Thoughts

Car battery is something that needs to be tested on a regular basis. It is because if the battery of your car is going to work below its actual capacity, the performance of your car will be affected significantly. Instead of waiting for your battery to start showing signs of any weakness, it is always better to keep your battery checking in a regular way. It is because testing the battery of your car alongside other components of the electrical system of your car can let you maintain the vehicle's performance in the best possible way.
