Battery Testing Equipment – Introduction and Usage

Even though batteries are rated to last for years, sometimes the batteries have to go through different circumstances which make the battery go bad. Well, it does not mean that the battery needs to be replaced. However, it means that the battery needs to be tested. The reason here is that testing can tell you about the root cause of the issue as well as the life of the battery.

In this way, you can make the battery and more efficient decisions about getting the battery repaired or replaced. When it comes to testing the batteries there are several types of testing as well as several types of equipment. So, here is everything you need to know about battery testing.

What are types of battery testing

Testing the batteries is not all about checking the voltage of the battery only or monitoring the water level inside the batteries. There are several things inside the batteries that need to be tested for knowing the cause and the way to treat that cause. So, here are some types of battery testing.

Impedance testing

It is the test done on a battery that is used to tell the performance history of each battery cell. With the help of this test, it can be easily identified which cell needs to be replaced by taking a look at the cells that have higher impedance. It is a non-invasive test on a battery.

Elector-chemical testing

This is the test that tells about the issues with the batteries like electrolyte dry-out as well as sulphation and some other battery conditions as well. Here frequency response and current are passed through the battery terminals to record the data and calculate the health of the battery.

Load Bank testing

It is the test that is used for the identification of the battery capacity. Here the battery is tested under normal load and peak load conditions for checking the way the battery holds a charge and performs. In this way, the old and nearly dead batteries can be easily identified.

Partial discharge testing

It is the battery testing method that tells whether there is an issue with the battery or the UPS. Here the battery is only discharged up to a maximum of 80% which tells about the battery condition. This test also tells if there is an issue with the UPS.

Gravity testing

This is a method where the electrolyte of lead-acid batteries is tested for its gravity. The meter tells whether you need to add more distilled water to the battery or not.

Which equipment is used for testing?

When the battery is being tested for several faults and conditions, several types of equipment are used for performing each type of test. As the equipment is different for each test, some things cannot be used for performing all of the tests. So, here are some of the equipment for battery testing.

Impedance testing equipment

It is the equipment that passes some AC through the battery with the help of probes. At the same time, instruments are taking the impedance readings, and then the readings are recorded in milliohms.

Elector-chemical testing equipment

In this equipment, there are probes attached to the battery terminal. These probes are used to measure the battery frequency response that it gives to the voltage signals passed through the equipment.

Load Bank testing equipment

For this type of testing the equipment includes several types of normal loads and peak loads which are used for discharging the battery. Similarly, there is some charging equipment included here as well.

Partial discharge testing equipment

This type of testing also includes some load that is used to discharge the battery and then some charger to charge the battery.

Gravity testing equipment

It is one of the simplest types of testing battery and the equipment here is simple as well. There is only one instrument made of a glass tube which has another glass sealed tube inside it with some markings. There is a rubber part attached to the back of the main tube along with a nozzle at the other end. In this way, the equipment sucks some electrolytes from the battery to test its gravity.

What is a battery test system?

A battery test system is a system that includes all of the battery testing equipment for testing the battery. All of it is digitally controlled with an intelligent system which makes the whole process very easy. So, the battery testing is done statically and dynamically. The battery test system can test the following things:

Charge rates and discharge rates

Depths of discharge

Voltage, current, and power

Temperature

States of health

States of charge

The benefits of a battery testing system

The battery testing systems come along with a lot of value because of their amazing benefits and here are some of those benefits.

Less time for running tests

Battery testing usually requires the battery to be removed from its usual system. So, the battery testing system can perform very quickly to make the waiting time less for you.

No need for labor

The whole system works on itself and there is no need to keep switching between testing equipment. It means that there is no need for labor when you have the battery testing system

More accurate results

As all the readings are recorded digitally and the results are calculated digitally as well there are almost no chances of wrong results and mostly all results are accurate.

Fewer chances of safety issues.

With the least need of changing through batteries and equipment, there are no safety issues like getting electrocuted from the battery or dropping the battery on oneself.

While these were some of the benefits, there are a lot of other benefits as well as having the battery testing system.

Conclusion

Testing the battery is always a beneficial thing whether it has some issues or not. Testing batteries once a year makes you aware of the condition of the battery. So, it is important to test the battery at regular intervals for the best life and performance of your battery. We hope that by now you know its importance and several types of equipment and its importance for the testing battery.
