Are Car Battery Testers Accurate?

If you have a vehicle at home, then you would have known the importance of having a battery tester at home. With the battery tester in your garage, you can be assured that your battery has enough juice to take a long run. IF your battery is not working as it should be, then it is recommended that you either charge it, or replace it with a new one. However, choosing either one of them is a hard thing to do, and this is where the battery tester comes in handy.

How the battery tester manages to check the battery health?

The battery testers are the electronics devices that precisely measure the current drawn by the battery. The conducting material of the tester is attached to the positive and negative ends of the battery and the meter measures the value of the current. The current shows whether your battery needs a charge or replacement. Usually, the process is quite simple and you won’t have to worry about the accuracy of the process. The process will help you get accurate results and you can easily decide whether you need a replacement or not.

What are the limitations of the battery testers?

Though the battery testers are a great tool to have in the car trunk or garage, they also have a few limitations that you should be aware of while relying on their results. The first thing to consider while using the battery testers is the type of battery you have in the vehicle. The battery testers have better accuracy and results for the alkaline batteries. However, if you have lithium batteries, then the accuracy of the results may be a bit confusing. The reason behind this variation is the fact that the lithium batteries’ current does not degrade seamlessly. This makes it hard to detect whether the battery needs replacement or not.

Also, numerous other factors define battery health. That means, if you are relying only on the current drawn from the battery, there are chances that you may judge the battery health wrong. So, instead of this, we will suggest you to take the car to the mechanic if you think that the battery needs a replacement for a further checkup. They have the professional tools and testing kits that can help you make a better decision. This will also help you know whether you should buy the battery or charge it manually.

Should we rely on the results from the battery tester or look for professional help?

To conclude, battery testers are a great tool to have. But when it comes to their reliability, there are numerous other factors that act on deciding the replacement. So, we will suggest you to take the battery testers as the first major step to decide whether the battery needs replacement or not. And if you think your battery is working just fine and it is not showing the accurate results on the meter, we will suggest you to go for the professional help that will help you check the actual issue with your battery health and can help you get the technical help, if needed.

Additionally, you can also opt for the pro-level battery checking kit that has all the equipment needed to check the battery, regardless of the type and size of the battery.
