Load Test Batteries- Introduction, Method And Care

Nov 24, 2020   Pageview:48

It is improper for you to jump into your vehicle and believe all is well with the batteries. Sometimes the battery might be down. And the earlier you know about this, the better it is for you.

There must be a way you can know if your battery is near its peak or if you should just do away with it altogether. If you can know the state of your battery before using it once in a while, it will help greatly. That is exactly where load testing for battery comes in. You ought to occasionally subject your batteries to load testing to know the strength of the battery.

Wait for minute – let us talk more about load testing for batteries before diving deep into the subject and discussing how it can be done to perfection. Here is what you need to know;

What is load test battery?

Quite frankly, before this subject will start making any meaning to you, we need to answer the question – what does it mean to load test a battery?

From a layman’s perspectives, battery load testing is simply about knowing exactly how much current is coming out of the terminals of a battery that has been charged. This is an essentially important process for batteries that are used in vehicles, as well as other types of batteries. The battery that is used in a truck or car is expected to deliver a high amount of power that can rotate the motor, which will ultimately lead to the working of the engine of the vehicle. Otherwise it will be difficult to power the engine and that means the vehicle will be inoperable.

With a process as such as this, it will be easier for you to identify a battery that will be useful to you and the one that will not be useful. You cannot just keep charging and using your battery. The quality of the output will keep deteriorating at a certain pace. But how much of the quality has been eroded away is what you are never sure of. That is why you need to subject your battery to this test.

There are a couple of ways through which you can achieve this purpose on your battery. And you might likely need to observe a few guidelines to ensure you are doing it the right way. If I should add, the guidelines talked about in the preceding statement are actually some straightforward instructions you need to follow. When you do it as you are expected to, you would immediately know whether the battery is delivering the current required for the purpose for which it is being used.

Can you load test deep cycle batteries?

On seeing this all over the internet, one can only conclude that several things are yet to be understood about battery load testing. It is like missing the point of the whole thing. If the real essence of this process is understood, certain questions will not arise. Well, we will consider the above question as a relevant one, and have it treated as such.

I would respectfully opine that you can do a load test on a deep cycle batteries. The reason for load testing is to identify the current delivery coming out from the battery terminals. So this equally works for a deep cycle kind of battery. As long as the battery voltage remains at its peak value, you can carry out load testing on its terminals. You just need to follow a few guidelines like we stated earlier and you would be fine.

Deep cycle batteries are liable to become a liability when they are not properly maintained. As one of its requirements, you need to use them well or they will become useless and unable to supply you with the required power. So one way to check out the health of the deep cycle battery is by doing a load test on it.

And the good part about this is that with the right information of your battery, you would know how soon you need to subject your battery to a deep cycle charging. That way, you will not blindly use your battery without know when the battery should be put through such relevant processes.

Therefore, I guess our question about whether a deep cycle battery can be load tested has been answered satisfactorily. Yes, load testing can actually work on deep cycle batteries.

Do you have to disconnect a battery to load test it?

After knowing what battery load testing is all about and how it can help you ascertain the status of your battery, the next thing is knowing how to do it right. This is of absolute importance because if it is not done accurately, you will end up getting wrong information of your battery.

All along we have been screaming about how battery load testing should be done with some guidelines in mind, perhaps, this is where we discussed a few of them. Before you connect your battery terminals to a load tester, you must ensure they are dry and free from any rust. It is necessary you get this sorted out because impurities have the capacity to compromise the whole process. Therefore, you must ensure no single amount of impurity of any sort is on the battery terminals before you commence the process.

The next thing is that you will have to disconnect the battery from the charger before you load test. If the battery appears to be connected to other electrical loads, it is imperative that you get rid of the negative ground cable before proceeding with the load testing. These ones are just a few of the instructions you need to abide by before carrying out load testing on that battery.


Battery load testing is done with an effort to identify the status of the current coming out from its terminals. It can be carried out on deep cycle batteries. And please make sure you disconnect the battery from any load before you commence the load testing.
