Wiring Batteries In Parallel Danger-Introduction, Battery Quantity And Testing

The need for batteries has drastically increased in the past few decades. This is because we have started to make almost every electronic device portable. From small things like the desk lamps and table clocks, to the large things like cars, everything needs a battery these days.

This is because the revolution of the field of electronics has been successful to be able to provide portable power to all of these devices. With the increasing needs of different types and sizes of batteries, it was not very efficient to create a different battery for every different application. This is why batteries are now connected in series and parallel orientations.

These different orientations help us to achieve different amounts of capacity, voltage, and current from the batteries. However, there are some dangers to doing this too. Here we will discuss all the factors about connecting batteries in parallel orientation.

Is it dangerous to wire batteries in parallel?

The first query that most of the people have about connecting the batteries in parallel orientation is that is it dangerous to do this. The answer can be yes and no, and it will depend on the way you use the batteries and the batteries that you will connect in parallel. Here we will discuss all about connecting the battery in parallel and its dangers.

For the circuit and electronic components.

When the batteries are connected in a parallel circuit, the voltage remains that same, but the current is increased. This can be beneficial for some devices. However, if the devices are sensitive and they do not have any protection circuit, then it can be very dangerous for the device.

This is because the current will be higher than that of a single battery and this can damage the electronic devices and the circuits as well.

For the health of batteries.

As we know that when the batteries are connected in parallel the voltage remains the same. Here one very important thing to consider is to connect the batteries that have some of the following things similar.

• Size and model.

• Chemical construction.
  

• Voltage and capacity.
  

When the batteries connected in parallel will have all of these things the same, they will efficiently provide the circuit with more power. However, if any of these factors are ignored , especially the similar voltage and capacity of the battery, it can be disastrous for both the batteries.

It is because the better battery will be constantly charging the bad battery. This will keep these batteries in an infinite loop of constantly being charged and discharged. It will have significantly adverse effects on the life of the batteries. In the worst cases, this can also cause a lot of heat and even a fire.

How many batteries can you run in parallel?

The next question that most of the people have is the amount of batteries that you can run in parallel. The answer to this is that there is no hard and fast rule for doing this as it is possible to theoretically connect as many batteries as possible. But practically it could be possible but not a very efficient thing to do.

So, here we will discuss some of the situations in which you can connect a different number of batteries in a parallel orientation.

Depending on the amount of current and capacity needed.

When connecting batteries in parallel, the first thing to consider is the need for the load. The load can be any electronic device or the circuit. The next thing to consider is that is there any protection circuit present in that device.

All of these things are very important to consider. It is because a protection circuit will ensure that the load will not be damaged because of any high current. Additionally, the requirement of the load will tell you about the number of batteries that you have to connect in parallel.

Most of the time, the requirement is more about the capacity of the batteries instead of the amount of current. This is because more batteries in parallel means that you can use them for a longer time.

It depends on the amount of batteries that you want to connect.

The next condition is dependent on the number of batteries that you have. If you are working on your projects, then you can connect as many batteries as many you have. Just do not forget to care about the facts mentioned above in the article.

Do you need to test wiring batteries in parallel?

While you are connecting your batteries in parallel, one thing to consider is to test the battery connections. The reason for this is because when 2 or more batteries are connected in parallel, if one of them is not connected correctly, it can cause a lot of problems.

So here we will tell you about some of the tests that you can do when you are wiring the batteries in parallel.

Testing the size and voltage of every battery.

The first thing to do is to test the voltage of the battery. You must do this test before connecting every battery. It is because once the batteries are connected, you will not be able to tell the individual voltage of each battery. One thing to note is that it is very important that you only connect the batteries with similar voltage ranges. This will improve the efficiency of the circuit.

Testing the connection after wiring.

Another thing very important is that you test the batteries after they are connected. This will not be able to tell the individual voltage of each battery. But it will be able to tell the total amount of current that you are getting from the circuit. It will also help tell about the total capacity of the batteries. As this will be very important when the batteries will be practically used.

So, it is very beneficial for you if you conduct a series of tests on the batteries before using them as this will not only increase the capacity, but it will also make the batteries more reliable.

Conclusion.

Connecting batteries in parallel can be very useful sometimes. But it can also have some dangers if not incorrectly. Here we discussed all about the connection of batteries in a parallel circuit.
