CR2032 vs CR2025 vs CR2016: Are they interchangeable?

Understanding the differences between CR2032, CR2025 and CR2016 batteries is important for understanding how to use them properly. They are all lithium-ion batteries that can be used in similar ways. The main difference has more to do with cost than anything else, but you should also understand which battery will give you the best performance at a given voltage level when using it in your device.

The “cr2032 vs cr2016” is a question that has been asked for some time. The answer is no, they are not interchangeable.

There are many different types of coin cell batteries available, and many of them appear the same or extremely similar. They are sometimes referred to as button batteries. If you don’t know the distinctions between CR2016, CR2025, and CR2032, you may easily confuse one for the other.

This short essay will explain the meaning of battery names and assist you in selecting the correct battery every time. The differences and similarities between the three battery types are also discussed.

CR2016 vs. CR2032 vs. CR2025: What’s the Difference?

The first commonality is in the battery naming method, and a little explanation will explain why.

CR: The letter C denotes that the battery has a Lithium Manganese Dioxide chemical composition. The letter R denotes the form of the battery, which is round in this instance.
The first two digits of the battery code show the diameter of the battery in millimeters. Each of these batteries has a diameter of 20 mm.
The thickness of the battery is indicated by the second two digits in the battery code. The CR 2016 has a thickness of 1.6 mm, whereas the CR 2025 and CR2032 have thicknesses of 2.5 and 3.2 mm, respectively.

What else do the CR2016, CR2025, and CR2032 have in common?

All three kinds of batteries are utilized in a wide variety of tiny gadgets, ranging from automobile remote key fobs to laser pens, children’s toys, and much more. The CR2032 battery is often used in personal computers to keep the CMOS memory alive.
Voltage: All three batteries have a voltage of 3 volts. They could theoretically all be used interchangeably, but we’ll get to that later.
All three batteries are 20 mm in diameter, as stated by the battery code.
The chemical makeup of Lithium Manganese is the same in all of these batteries.

What Are the Differences Between CR2016, CR2032, and CR2025?

The thickness and capacity of the batteries change significantly between the CR2016, CR2025, and CR2032.

The thickness of the three battery types differs.

The most noticeable change is the thickness of the battery. The thickness of the battery is described in tens of millimeters by the battery code, therefore the 2016 is 1.6 mm thick. The only physical difference between the batteries is their thickness.

One disadvantage of adopting a CR2032 instead of a CR2016 is the difference in thickness, but we must also consider the battery capacity.

Battery capacity differences

The varying thicknesses are due to the capacity of the battery. The capacity rises as the case thickness increases. Capacity is critical for a variety of reasons, including:

Some gadgets will not operate with a smaller capacity battery.
The larger the battery’s capacity, the longer it will last.

The capacity of the CR2032 is more than twice that of the CR2016:

But what exactly does this capacity rating imply? Here’s a quick comparison to show how the two vary.

The CR2016 would last 4.5 hours, the CR2025 for 8.5 hours, and the CR2032 for 11 hours if all three batteries were used to power a single 20 mAh LED bulb. So it’s understandable if you want to use a CR2032 instead of a CR2016, but are they interchangeable?

Is it possible to interchange CR2032 vs. CR2025 vs. CR2016?

Yes, the three battery types are theoretically interchangeable. There are, however, certain challenges.

The diameter and voltage of all three batteries are equal, implying that substituting one kind for another is not an issue. The issue stems from the various thicknesses of the batteries. The smaller battery will be too loose in the compartment, whilst the heavier battery may not fit or may cause harm if you push it in.

Interchangeable batteries: CR2032 and CR2025; CR2025 and CR2016

Because the difference in thickness between the CR2032 and the CR2025 is just 0.7 mm, either one may generally be used. The difference in thickness between CR2025 and CR2016 is also 0.9 mm.

This should operate without issue as long as the batteries fits snugly without hurting any component of the battery casing.

Is it possible to use a CR2016 battery in place of a CR2032 battery?

The CR2032 may theoretically replace a CR2016 battery because of their same diameters and voltages.

However, since the CR2032 is twice as thick as the CR2016, it may be too thick to fit into the battery slot without bending or injuring it.

Can I replace a CR2032 battery with two CR2016 batteries?

Many people believe that since the CR2032 is precisely twice the thickness of the CR2016, they can simply use two CR2016s instead of a single CR2032. While this seems to be correct in principle, it has a problem. You can connect two CR2016 batteries in series and get a voltage output of 6 volts by stacking them on top of each other.

This is not a good idea!

While the greater voltage may not harm anything, there’s a chance it will, so don’t try it.

Solution: Stacking a penny with CR2016

If you need to replace a CR2032 battery but only have a CR2016 on hand, there is a technique to make it work without causing any harm. You might use a cent coin instead of two CR2016s to get the desired thickness.

A penny is the proper diameter, and it will be 1.52 mm thick when minted, which is almost similar to the CR2016. The metal coin also has strong conductivity and will firmly retain the battery.

Should I buy a CR2016, CR2032, or CR2025 battery?

Frequently Asked Questions

Can I use a CR2032 battery instead of a CR2016 if it fits?

A: Yes. You would just have to be careful not to overcharge the battery or it will blow out.

Can I use CR2025 to replace CR2032?

A: The CR2025 is a more modern battery that offers roughly double the lifetime of its predecessor, the CR2032. However, despite being better than its predecessor in many ways, this doesnt always mean you can use one instead of another.
