This review is focused on showing the best battery testers out there. If you are interested in getting the best battery tester, you are at the right place, as we have dedicated time to select the best battery testers that will serve you.

Read through, to discover for yourself the best battery testers out there.


Battery Types

Normally, the car batteries have different classifications, like a wet cell, deep cycle, SLI and lithium-ion. It is preferable to select a battery load tester that perfectly matches with your specific car battery.

However, a car battery tester only takes the reading and delivers the output voltage of the vehicle batteries. It is always better to look for a tester that has a wide voltage reading output. In general cases, a tester must come with a voltage output rate of 9 to 16-volt.


The screen or display is the main part of a tester where you can actually monitor the results. So, you need to choose a unit that comes with a large-sized display.

Nevertheless, a load tester with backlit display delivers the readings clearly even in the dark or low light condition. A display with a large digit output helps everyone to see the voltage output with stressing their eyes.

Connector Leads

The connector leads are one of the major components which have direct contact with the vehicle batteries. The connector leads with large sizes are always versatile enough to fit the majority of the battery connectors.

Therefore, it is advisable to select a battery load tester with a rubber-coated connector lead handle.

Slip-Resistant Back

We often have to place the tester in very odd positions while testing the batteries. So, you should opt for a tester that comes with a slip-resistant back.

In this way, you can prevent the tester from getting damaged caused by slipping. A tester with soft rubber grips provides protection to the machine.

Rugged design

The tester should be built to withstand rough handling, knocks, bumps, and scraping.

The range of functions

You should go for advice that can measure different parameters including voltage, current (amperes) CCA (cold cranking amperes) and much more.


It’s a known fact that some companies deliver better products than others. It’s therefore important to concentrate on well-known and respected brands


Most of the time, the testers are very much easy to operate and do not involve critical operations. For your utmost convenience, you should check if the manufacturer is providing manuals for the device or not. Generally, a battery load tester supports out-of-the-box usability.


It is better to look for a machine which is light in weight and compact in size. A travel-friendly model is lesser than 1-lbs.
