Know Your Battery – A Systemic Guide to Battery Testing

Man. Testing Large Battery

Do you have a research unit, a battery production facility or your project involves using batteries? One of the things that you MUST ensure works well to guarantee optimal performance of the equipment or facility is the battery. To have the assurance that the batteries will deliver full performance when called upon, they need to be tested, but what is the best method?

This post is a comprehensive guide to battery testing to help you understand how they work and only select the most effective battery load testers.

Visual Battery Inspection

This is usually the first step in battery testing. By physically inspecting the battery, it is easy to locate corrosion, leaks, and cracks. These problems are used as indicators that a battery might have more serious issues that needs to be checked. However, the visual inspection does not reveal the state of the battery’s capacity, state of charge, or health. This is why you should always use battery testers for more comprehensive results.

Voltage Testing

This test is used to check the float voltage in a battery. If your battery tester shows it has low float voltage, it is an indication that the battery is unable to provide full capacity. It might also be an indication of high sulfation. If the voltage is too high, it is also not good because it might be a case of overcharging, and it can result in premature grid corrosion and high temperatures.

Float Current Testing

When selecting battery load testers for your facility, it is important to check whether they can allow you to test the float current. If your battery has a high float current, it is likely to be an indicator of thermal runaway. Alternatively, it might be a sign of a ground fault, short circuit, or high voltage. Although a high or low float current is an indication that something is amiss about the battery, normal levels reveal nothing about its state of health or capacity.

Specific Gravity Measurement

This testing is used to find out the ratio of the density of a liquid used in the battery to the density of water. The test is instrumental in establishing how much sulfate is in the electrolyte. It is a fantastic method of determining the state of health (SOH) of a battery. However, it does not show the capacity of the battery.

Discharge Testing

One of the recommended methods of checking the status of a battery is discharge testing. It is recommended by the IEEE standards, especially during installation and after two-five years. To do a complete discharge test, the battery should be taken out of service for the entire testing period, which can last for several days.

When selecting the preferred testing method, it is essential to factor in the type of battery and the manufacturer’s recommendation. For example, lithium-ion battery testing is the most preferred method for Li-Ion batteries. So, it will be a great idea to understand your battery types before setting off to buy battery testers. You might also want to bring onboard some experts for your research or manufacturing facility.
