Difference Between CR2025 Battery and CR2032 Battery

Author: Iggy Date: 11 Jun 2021  2020

Button cells are used to power small portable electronics devices. It has a round diameter, and two metal electrodes. An electrolyte that is placed between them controls the flow of ions that make the electricity.

Button batteries are widely used in various miniature electronic products due to their small size. It is generally used as a backup power supply for various electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, memory cards, remote controls, etc.

What is BUTTON CELL? What does BUTTON CELL mean?

But sometimes button batteries like CR2025 and CR2032 are too similar! When we buy them, we often get confused. Consumers, confused by these seemingly indistinguishable buttons, were helplessly left on the battery purchase page, annoyed while hesitant.

This post will help you remove the fog of the batteries CR2025 and CR2032. We'll help you understand what the CR2025 battery and the CR2032 battery are, their similarities and differences, and whether they can be replaced when in use.

IV. What are the similarities between CR2032 and CR2025 batteries?

Both the CR2025 and CR2032 are 3-volt lithium coin or button cells measuring 20mm in diameter. As far as technology is concerned, both CR2025 and CR2032 batteries have the same voltage, chemistry and diameter. Both batteries can power small devices such as calculators, computer motherboards, fitness appliances, laser pens, POS systems, safety devices, sensors, smart carport keyless input devices, wrist watches, and various medical devices such as clinical thermometers, glucose monitors, heart pacemakers, and tensiometers.

All major battery brands such as Duracell, Energizer, Panasonic, Philips, Maxell, Murata (formerly Sony), Renata and others carry both the CR2025 and CR2032 batteries in their product catalogs as two of the most widely used batteries in the world.

V. What’s the difference between CR2032 and CR2025 batteries?

The obvious difference between the two types of batteries would be the thickness. The CR2032 is 3.2mm thick and the CR2025 is 2.5mm thick. Since the CR2032 is 0.7mm thicker than the CR2025, it has a higher capacity (mAh) to deliver the current to the load. The standard CR2032 can nominally deliver 225mAh, while the average CR2025 can nominally deliver only 160mAh. Due to its smaller capacity, the thinner battery may not last as long and may need to be replaced sooner.

CR2032

CR2025

Pros

1.Higher capacity, which will lead to a longer life.

2.Perfect for watches, heart monitor scans, and hearing aids.

1.It takes less space, and you won’t worry about damaging the battery when you put it in the device

2.It is best used for children’s toys and calculators.

Cons

Takes more space

1.Less capacity

2.Shorter duration


VII. Can I use a CR2025 battery instead of a CR2032?

For as long as either fits in the battery compartment, the CR2025 and CR2032 can be used interchangeably with minimal effect, although the CR2032 is likely to last slightly longer simply because it has a higher capacity (mAh). Here's a tip: if you're in a pinch with only the CR2025 available, you can fold up a piece of aluminum foil or another conductor to fill up the 0.7mm extra space. Place it on the (+) side of the battery and close the compartment to hold it in place. Ensure good contact with the battery and the spring otherwise there is a risk that the battery will be intermittent.

Another good way to explain the similarity and difference between the batteries CR2025 and CR2032 is by looking at their names and understanding the code used by the International Electrotechnical Commission (IEC) to name these batteries. The combination of letters and numbers used to name the batteries is not arbitrary. It tells you a lot about the physical attributes of the battery. The two letters tell you about the chemistry of the battery. C means it's a manganese lithium dioxide battery. R indicates the round (cylindrical) shape. The first two numbers concern the diameter of the battery, while the last two numbers relate to the depth of the battery. It is essentially said along these lines that the CR2032 has a diameter of 20.0mm and a thickness of 3.2mm, while the CR2025 has a diameter of 20.0mm and a thickness of 2.5mm.
