Guide to Buying the Best Car Battery Testers

Keeping your car battery charged and maintained is very important. As you just discovered, there are some great car battery testers available on the market. These are the best car battery testers for you to choose from. But before making a choice, there are some important factors you need to consider. The question now is what important factors should you consider when buying a car battery tester? Let’s explore.

Type of battery tester

Since the main purpose of the device is to test batteries, think about what type of battery tester you need. This will depend on what you need and if you’re planning to perform any repairs on your vehicles.

Load tester
This type of tester usually comes with a large resistor. When you engage the resistor, the tester will take on an electrical load as the car’s starter motor. Therefore, it will be able to help you determine if your car’s battery is functioning properly. But before using this type of tester, you need to make sure that your battery is fully charged.

Conductance tester
This is the simplest type of tester available, but it’s very handy. Using it would allow you to see your battery’s current voltage. After testing, you can determine whether or not your battery needs charging or if you already need to replace it.

Display

The display is where you see the results of the test. It should be big enough so you won’t have to squint just to get the reading. You may also opt for testers which have backlit display screens so that you can still see the reading even in conditions with low lighting or visibility.

Connector leads

Most car battery testers come with the connector leads. These leads should be big enough so that they can fit different types of battery connectors. Also, if you plan to use the tester for longer periods of time, choose one which has an ergonomically designed handle for the connector lead with a soft material covering it.

Anti-slip feature

Finally, you should also consider the back portion of the car battery tester. Some models come with an anti-slip feature which is very handy. There are times when you need to place the tester in a position where it might slip and fall to the floor. But if the device has an anti-slip feature, this won’t happen.

Look for this feature to keep your tester safe no matter how awkwardly you position the device while testing. The anti-slip feature would be a soft, rubberized material which will grip your tester safely in position.

How to use a car battery tester

Knowing how to use a car battery tester is as important as knowing how your car battery functions. Apart from finding the best car battery tester, you should also know how to use the device properly. That way, your newly purchased device won’t break down after just a couple of uses.

Find the battery connectors of your vehicle
The connector leads of battery tester have a positive and negative charge. These connectors will have color-coded wires to indicate their polarities. Make sure these connectors are always clean to prevent rusting or corrosion.
Before you start, attach the connectors to your car battery making sure that you match the appropriate polarities. After doing this step, you can switch your battery tester on.

Check the voltage
After turning the device on, the tester should start doing its work and after a short while, provide you with the results you’re looking for. If your battery is in good condition, the tester will indicate this. It will also help you determine if you already need to charge or replace the battery of your vehicle.

Assess the alternator
Finally, testing the battery of your car isn’t the only thing to do. You should also check the battery’s alternator to see if it’s properly charging the battery. At this point, you would have to switch on the engine of your car.
Don’t disconnect the tester from your car battery when you start the engine so that it will show you whether the alternator works or not. The tester should show you a voltage between 13.7-14.7 as this is the normal voltage that an alternator sends to a battery while charging. If you see a lower value, then your alternator might have a problem.

The Verdict

When you look at a car battery tester, the first thing that would come into your mind is that it’s a very simple device. However, there’s still a lot to consider when choosing one. From the type of battery to the extra features, we’ve provided you with a lot of information to make choosing the right model easier for you.
