Load testing is one of the most accurate ways to check the health of a lead-acid battery. It measures the battery’s ability to deliver current under a load. This test can help determine if the battery is capable of supplying the required current for a particular application. To perform a load test, you will need a load tester.
By regularly testing your batteries, you can extend their lifespan and ensure that they’re always in good condition. Overall, how a battery tester works is by measuring the voltage of the battery. If the voltage is low, then it needs to be replaced. There are many different types of battery testers, but most of them work in a similar way.
1. Electronic battery tester The electronic and digital types are the most common ones used for testing the remaining capacity of a battery. Most digital models feature an LCD, showing the result in a clear and easy to read format. Depending on the model, the result is displayed in the form of bars or a graph.
Often displayed in the form of bars or a graph, depending on the particular model, this enables quick reading and analysis of the test results via a user-friendly interface. A domestic or household battery tester is normally used for rechargeable cylindrical batteries including AA batteries, AAA batteries, and 9V PP3 batteries.
If the voltage reading is lower than the manufacturer’s specifications, the battery may be weak and need to be replaced. If the voltage reading is within the manufacturer’s specifications, the battery is likely in good condition. To get a more accurate reading of a lead-acid battery’s health, you can use a hydrometer.
You will need to insert the battery into the tester, ensuring the positive and negative contacts on both the battery and the tester match up correctly. Make sure that the battery is firmly secured in place before you take the reading.

BU-905: Testing Lead Acid Batteries
There are three common testing concepts: Scalar, vector and EIS with complex modeling (Spectro™). Scalar is the simplest of the three. It takes a battery reading and compares it with a reference that is often a resistive value. Most single-frequency AC conductance testers measuring CCA are based on the scalar concept.
