How to Stack Two CR2032 Batteries?

You are right here now to know about how to stack two CR2032 batteries, right?

At the same time, you are too much frustrated after failing to find the impactful and compact guidelines over here and there. However, you have come to the right place indeed. I will discuss the process in detail to assist you with some other related facts and factors. 

Hopefully, you will not be feeling helpless anymore about the process guideline after exploring the article. Let’s enjoy.

What Is Stack Battery?

Stacking technology means connecting the anode and cathode of a cell in parallel or in series to increase the energy density of a battery by 5% and the cycle life by 10%. The technology reduces the cost by 5%. With stacking technology, the battery cell gets a low internal resistance, long lifespan, high space usage, and high energy density. 

However, the CR2032 is one of the many types of available batteries, which we use for smaller electrical and electronic devices. The CR2032 battery is a non-rechargeable battery that uses lithium chemistry. It is a 240 mAh coin-cell battery with a cut-off voltage of 3 volts. 

We generally use this battery for-

• Wristwatches
• Pocket calculators
• Hearing aids
• Car key fobs
• Mini flashlights
• Guitar tuner
• Motherboards (backup)
• Small toys
• Kitchen scales
• Remote control
• Medical devices
• Digital Vernier calipers 

We sometimes do not get the battery voltage as per our requirement. Nevertheless, if a circuit requires 6 volts, you can stack two 3-volt CR2032 batteries in series to supply the needed voltage. The capacity of the circuit will remain the same.

For instance, if each CR2032 has a capacity of 225 mAh, our total circuit would still only have 225 mAh. Sometimes running with one cell isn’t enough. That time you need to stack batteries. Now I’m going to describe the process below.

How to Stack Two CR2032 Batteries?

There is no need for any special circuitry to stack two cr2032 batteries. It is a pretty regular practice. If we stack two cr2032 batteries, both batteries will distribute the load evenly. And there will be minimal cross-feeding (almost zero). However, to stack two cr2032 batteries all you need to follow step by step that I have given below-

Step 1.

Firstly, you need to ensure that the two batteries are at the same state of charge when installing them. If not, the one with the higher voltage will try to charge the other first. 

Step 2.

Secondly, you should line up the negative (-) ends of one cell with the positive (+) ends of the next.

Step 3.

Thirdly, batteries that need to be stacked are sometimes inserted into tubes or detachable inserts that you can remove after use.

N.B. CR2032 batteries should not have a charge current of more than 1uA and when these cells are connected in series, they will charge and harm themselves internally, increasing their internal resistance and possibly exploding.

Accordingly, with series circuits, a faulty battery in the series can cause the voltage to be lower than necessary, which may lead to an equipment failure among other.

What Will Happen When We Stack Two Batteries?

The following information will help you to understand what can happen if you stack two cr2032 batteries.

• When you connect matching batteries with the same polarity, there may be a little balancing current at first, but the discharge will always be distributed evenly across the parallel batteries.

• When you connect one battery with reverse polarity, it acts as a short circuit between two cells in series, causing both to be charged quickly and self-heating up to 80°C.

• If both batteries have the same polarity but different charging states, the stronger battery will charge the weaker battery. It could cause a short circuit (from dendrite growth) within the weaker battery, which would cause the strong cell to weaken as well.

Frequently Asked Questions (FAQs)

How Do I Stack Button Batteries?

Button batteries are small round batteries that we generally see in watches and other small electrical devices. You might be unsure how to stack them into your device if you haven’t done it previously. To stack button batterie you can connect the Positive poles, then the Negative poles to each other. Then, you need to connect the first battery to the positive and the last battery to the negative.

How Do I Hook Up Two Lithium Batteries?

If you want to stack multiple batteries, you need to balance them first. That means you should make sure that they all must have nearly the same voltage. The voltage between batteries being stacked must be 1/2 Volt or less. When all batteries are fully balanced, you can then stack them together for use with the power module placed on top of each other.

Can Button Batteries Be Stored Together?

To store the button battery, you need to keep them in its original packaging. If it is not possible then you need to tape them with non-conductive tape and then keep your batteries in a plastic container. But you have to check that those are of the same size. As different size button batteries will react with one another.
