Buying Guide


Once you’re on your way to buy a battery load tester, you need to consider certain factors to ensure that you don’t make a costly mistake.

There are so many options to choose from, and if you’re careful enough, you will find the best car battery load tester for your car. The following features are not all-inclusive, but they can set you on the right path to buying a perfect battery load tester for your car.

1. Battery Type

You first have to consider the type of battery you want to test. Most testers work on a limited battery voltage, i.e., 6V and 12V, or 12V and 24V. You don’t want to buy a tester that is more compatible with a different battery voltage to avoid damaging your battery.

Some testers have a wide range of voltages that cover several battery types, but they might be more expensive.

Also, some battery testers only work on select battery types, like wet cells, flooded cells, and AGM batteries. However, you can find good-quality testers that work on several types of batteries.

Those types are best, especially if you want to test several batteries. The vehicle using the battery is also important to note as some testers don’t work on a motorcycle, marine, or truck batteries.

2. Type of tests

The types of tests you want to perform on your battery and car system matter when choosing a battery tester. That’s because some are specifically for battery analyses, battery charge, voltage, and general health. While some testers can also run tests on your vehicle’s starting and charging systems.

Other tests run by testers include engine system load test, maximum load test, and start-upstart-up system tests. You can find a tester that runs many tests, but not likely all of them. So, you have to pick what tests you need and choose accordingly.

3. Clamps

Clamps are often overlooked, but they play a role in how well a battery tester works. A lot of testers use the 4-wire resistance test to check the battery voltage, and without the right clamps, you may get incorrect measurements.

The best clamps are heavy-duty copper-plated clamps that are corrosion-resistant. They should also be able to penetrate any corrosion that may accumulate on your battery terminals for the best connection. You also need them to stay in place during the tests. However, ensure that you place them correctly to avoid damaging your battery.

4. Cold Cranking Amps capacity

Cold-cranking amps measure the starting power of your battery, and the higher it is, the stronger your battery. For this reason, you need a battery tester that operates with a wide range of CCA capacity. If you have a 12V battery, your tester should have a range that reaches at least 850 CCA to test the battery properly.

5. Ease of Use/ Portability

The purchase of a battery tester eliminates the need to visit the mechanic now and then. Hence, you need a battery tester that doesn’t require a degree to use. It has to be small and lightweight enough to carry around, yet sturdy enough to hold up to frequent use.

You also need one with an ergonomic design and a wide and clear screen to read the results. Some testers are so small that you can carry them around in your bags and pockets, so you don’t get stranded in the middle of a car trip.

6. Safety

Apart from making sure that you’re safe while using battery tester, you need to protect your battery also. A useful safety feature like the reverse hook-up protection feature keeps your battery from damage. The input protection feature also protects you and your battery from sparks caused by incorrect clamp placement.

7. Additional features

The additional features on a battery tester can improve your experience with your tool. An extra carrying case aids portability and storage, while a printer gives you the option to keep hard copies of your results.

Some testers have signal lights that represent your battery’s state, or a backlight for reading your results in low light. These accessories may increase a tester’s price, so you shouldn’t get carried away with something you don’t need.

FAQs - Frequently Asked Questions

1. What does a fully charged 12V battery read?

When a fully charged 12V battery is at rest, it should read anything from 12.6V and above. However, when the engine is running, it should read at least 13.7V and up to 14.7V.


2. Do I need to test my battery even when it’s not showing any bad signs? 

Yes. A battery load tester runs tests on your batteries, whether they are showing signs of damage or not. This way, you can identify any faults that may come on time.


3. How do I run a load test? 

You run a load test with a car battery load tester. The steps of running this test depend on the tester you have, but they are usually stated clearly on their menus.


4. How do I know when my battery is bad?

There are various reasons why a 12V battery can be dead. If the voltage readings are at 0V, then it is entirely dead. If it has a maximum reading of 10.5V while charging, it may have a dead cell.


5. How does a battery fail a load test?

If the battery is flat dead, it will read 0V from the beginning of the test. But, a battery may start well and suddenly start dropping. This is an issue. Sometimes a battery can read fully charged when it is at rest, but fail when put under a load test.


6. How many CCA do I need to start my 12V battery?

Cold-cranking Amps rate is starting power, but it alone doesn’t determine when or how your car will start. A good CCA rating for a car is 300, but this can change in colder or warmer temperatures. Thus, a good CCA rating is not set in stone.


Our top pick

The search for the best car battery load tester can be more trouble if you don’t go about it the correct way. There are several options you can choose from. However, your battery and car will determine the right option.
