Paralleling Batteries- Introduction, Result And Cycle Life

Batteries play an important role in our lives. They are related to almost every electronic device that we use in our daily routine. This is because most of the devices have been made portable and they get power from the portable power source that is a battery.

As most of the devices use the batteries in either series or parallel connection, people feel curious about the effects of connecting batteries in different ways. So, here we will elaborate on the parallel connection of the batteries and its result in different aspects.

Can you run two different batteries in parallel?

This is the most asked question about connecting the batteries in parallel. Most of the people asking these types of connections are either working on repairing their device or they are working on a do it yourself project. So, if you are thinking if you can connect two different batteries in parallel, then the answer is no.

This is because the most important rule of connecting the batteries in parallel is that they must be the same in their voltage and capacity. This is because if you ignore this very important rule, you will end up facing some consequences for doing this.

Consequences of running 2 different batteries in parallel.

When you connect two different batteries, one will have more voltage than the other and, in this case, the better battery will start charging the battery that is not that good. This will cause problems more than you can think of. Some of the problems that you might have to face two different batteries are discussed below.

Decreasing the efficiency of the batteries.

As one of the batteries will be charging the other one, this will decrease the efficiency of the batteries. This is because the better battery will never be able to provide all of its capacity to the desired use and the bad battery or the battery with low power will always be using the power of the better battery to charge itself.

So, not only the individual efficiency of the batteries will decrease, but the efficiency of the whole system will also be decreased.

Permanent damage to the batteries.

As when two different batteries are connected, one will be constantly charging the other and the other one will be constantly being charged. This can cause serious permanent damage to the batteries in the following methods.

• Reducing the capacity of the batteries.

• Reducing the ability to provide power.
  

• Reducing the life tenure of the batteries.
  

• Causing damage by producing heat, sparks, or fire.
  

What happens when you connect batteries in parallel?

Although connecting two different batteries can leave you in some serious problems, doing so with the same batteries can provide you with impressively productive results. Here we will discuss what happens when you connect the batteries in parallel and how things get productive by doing so.

The effect of parallel battery connection on the current of the circuit.

When you are connecting two similar batteries in parallel, you are connecting their same terminals. In this way, the battery configuration provides a significant increase in the amount of current provided by the batteries.

The effect of parallel battery connection on the voltage of the circuit.

When you connect the batteries in parallel, the current increases but the voltage remains the same, which means the batteries in parallel can be used in place of a single battery. This is because the voltage remains the same, but the overall capacity of the system has increased.

Some applications and benefits of using the batteries in parallel.

Here are some of the applications and benefits of connecting batteries in parallel.

Reliable system.

Consider that you have a system that accepts a 6-volt battery. Now if you connect two 6-volt batteries to it in a parallel configuration, the system will become more reliable. This is because if one battery fails to provide power, the other one will provide enough power to keep the system going.

More power generation.

As the current is increased in a parallel configuration, the power in the system increases. This means that you can do more powerful operations with this system.

Do batteries in parallel last longer?

One last concern that most of the people have is that if they connect their batteries in parallel, will their batteries last longer. Here we will use an example of a simple power bank circuit that uses 18650 batteries and is capable of connecting 1 or 2 batteries at a time in parallel circuit.

By different examples, here we will elaborate what is the effect of parallel configuration on the batteries.

The effect of parallel battery connection on the single charge life.

If we compare the life of a single charge, we will see a significant difference in the battery backup provided by 2 batteries connected in parallel rather than a power bank with 1 battery. This is because the increase in batteries will also increase the total capacity of the system.

Even if we take 2 power banks with a single battery each, the winner will be a single power bank with 2 batteries connected in parallel. This is because, in this system, the power loss will be less.

The long-term effect of parallel battery connection on the life of the battery.

In this case, we will compare the life of the battery. If we compare a power bank with a single battery and one with 2 batteries connected in parallel, the winner will still be the power bank with 2 batteries connected in parallel.

This is because the single battery will have less capacity and it will need to be charged again and again. This will make it lose its life quickly as compared to the power bank with 2 batteries.

Conclusion.

Having adequate information about what you are using is very important as this information can help you at any point in your life. Here we discussed some of the most amazing factors about connecting batteries in parallel circuits.
