Buying Guide for Battery Load Testers

Check out the following list of the main parameters while you buy battery load testers.

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.

Screen:

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.

User-Friendliness:

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.

Portability:

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.

Conclusion

If you are buying a battery load tester for the first time, you can be quite confused as to which one to buy. Different battery load tester has different features and compatibility. Therefore, go through the buying guide to understand the parameters and features well. Then you can understand which battery load tester will be perfect for your vehicle and to get all the desired parameters on display.
