Battery Tester Buyer’s Guide

It can be difficult to choose just one amazing battery tester when there are so many excellent ones available. We realize how difficult it may be, which is why we created this thorough buyer’s guide to help you learn everything you need to know to choose the best battery testers for your car.

Why You Want Your Own Battery Tester

The fact that businesses like AutoZone will test your battery for free is a typical defense against purchasing your own battery tester. Even though that is wholly accurate, you still ought to purchase your own battery tester.

Here, we’ll explain why that is the case by outlining three reasons for you to get a battery tester.

Added Convenience

There’s a strong possibility that the reason you need to test your car’s battery is that you can’t get it to start. The last thing you want to do is remove your battery from your car and carry it to the store only to discover that the issue is not with the battery.

You can check the battery in your car without leaving the comfort of your house if you have a battery tester of your own. These tests are so compact and lightweight that you can even check the batteries in your car while you’re on the go!

Higher Accuracy

Although convenience is a big selling factor for owning a battery tester, it is not the main justification for doing so. That is, doing a job yourself is the only way to guarantee that it is done correctly.

While this may seem a little over the top or paranoid, the truth is that auto parts shops are much more likely to label your battery as defective even if it isn’t. This is necessary since no battery tester can determine whether a battery has to be replaced if it hasn’t received a complete charge.

The issue with part retailers is that they won’t tell you this and are quick to suggest a replacement because charging a battery takes time. However, if you perform the task yourself and use a high-quality tester, you can decide for yourself when it’s time to replace your battery. You might even get another year or two out of your battery before the tester pays for itself.

No Conflict of Interest

You might be curious as to why a parts store would advise replacing your battery even if you didn’t require a new one. The first thing to consider when checking a battery is how long it takes to charge it.

Second, the parts store where you are would dearly love to sell you a new battery. If you can keep your battery charged and running, the parts store loses money; if you require a new battery, they get to tear you apart and sell you the parts!

If you don’t know what you’re searching for, it’s a really simple sale. Because even if you just need to charge the battery, the battery tester they employ will indicate that you need to replace it. When that occurs, you end up purchasing a battery that you don’t actually need, and the part store makes some money off of you.

How You Get Accurate Results

The best tools available are only as good as the person utilizing them, just like everything else in life. For this reason, we wanted to take the time to list a few steps you should follow to ensure your battery tester produces reliable results. Here are a few frequent mistakes individuals make when checking the battery in their car.

Disconnecting the Battery

Just to be clear, this step isn’t always required. The option to test the battery while it is connected to the vehicle is available with some battery testers. In actuality, the charging and starting system can only be tested if it is still connected.

The majority of simple testers, however, require you to disconnect the battery in order to receive reliable results, even though certain battery testers can check the battery while it’s still connected. That’s because you’re simply attempting to test the battery, and the findings may be tainted if there is a parasitic draw or another issue elsewhere in the car.

When in doubt, detach the battery to be safe and obtain the most precise readings.

Charging the Battery

When your car won’t start, the first thing you should do is connect the battery tester and diagnose the problem. But before testing your battery again, put it on a charger if the tester reads less than 12.6 volts when you connect it.

This is due to the fact that as the battery’s voltage rises, the cold-cranking amps will as well, which could alter the test’s outcomes. If there is no voltage for your battery tester to deal with, it cannot determine whether the battery is functioning as it should!

Checking the CCA

This is not an issue with any of the battery testers on the list, but far too many people believe that a voltmeter is sufficient for battery testing. Not at all.

That’s because a bad battery is still possible even if the voltage checks out. You check the voltage and the amperage when you connect a battery tester. Therefore, purchase a reliable battery tester and check the voltage and amperage.

What To Look For in a Battery Tester

It’s very likely that a set of batteries you’ve been using for a while no longer has any charge. However, you should think about testing the charge they still have before discarding them. You will need to utilize anything like the top battery tests mentioned above in order to accomplish this.

All of these battery testers have been mentioned along with their key features and available options to help you choose the best one. Additionally, in order for you to simply learn everything about battery testers, we have the following comprehensive shopping advice for the finest battery testers available:


It is crucial to confirm that your battery tester is completely compatible with the batteries you want to test before performing any other battery tester-related checks. The majority of battery testers on the market are typically designed to test domestic and popular battery kinds. This can apply to button batteries as well as battery kinds including AA, AAA, C, D, 1.5V, and 9V.

However, other battery testers, including 12V and 24V batteries, are available that might be made for testing car batteries. Depending on the batteries you want to test, each of these solutions is excellent and suited for the job.

Dial Type

You should test a battery after confirming that it is compatible with your battery tester. Additionally, the battery tester’s dial will indicate how much charge is still in the battery when it is inserted. However, as different battery testers can produce readings with varying accuracy and precision, not all of them have the same dial.

There are a few options that will offer a digital dial, while the majority of battery tests have an analog dial with good to average accuracy. These digital knobs provide incredibly accurate readings about the amount of charge remaining in your battery tester.

Form Factor

You might even want to have a battery tester in your toolbox so you can use it whenever necessary. However, this is only feasible if your battery tester is compact enough to always be maintained in your toolkit. In other words, it is very advised to check the form factor of your battery tester because a small, light tester will be quite useful. Since having lower dimensions is usually desired, many battery testers will list their weight and dimensions alongside them.


It is vital to ensure that your battery tester continues to operate without any problems because it is designed to accurately display the amount of charge still in your batteries. As a result, it is always a good idea to examine the battery tester’s included warranty. While the majority of battery tests on the market come with a 30-day warranty, there are some other options that have a 1-year warranty. For your peace of mind, you may even locate a few battery testers with a 10-year warranty if you’re searching for something extremely dependable.
