CR2025 VS CR2032: Similarities

Both are 3V button cells, they have the same diameters and the same chemical composition.

Some of the best manufacturers of these batteries are Maxell Pack, Duracell, Panasonic, Philips, Energizer and etc.

Philips has demonstrated it’s quality many times when it comes to batteries, this time surprising its consumers with a pack of 20 batteries that are suitable for cameras and children’s toys.

Duracell has won a large number of consumers in recent years, due to its quality and price. Their batteries are one of the best on the market, if you buy them, we are sure that you will not regret it.

CR2025 VS CR2032: Differences

Thickness

The CR2025 and CR2032 are both 3V button cells have identical diameters but CR2032 is 3.2mm thick while CR2025 is 2.5mm thick. Although there is a very small difference in thickness, and many will seem negligible, the difference is large. The difference in 0.7mm will be reflected in capacity and duration.

The winner is the CR2032!

This battery, because of its larger thickness, will have more capacity and may last much longer than the cr2025. If you are buying a battery for a hearing aid or watch, the cr2032 is a better choice.

Pros and Cons

CR2025

Pros:

  • It takes less space, and you won’t worry about damaging the battery when you put it in the device
  • It is best used for children’s toys and calculators.

Cons:

  • Less capacity
  • Shorter duration

CR2032

Pros:

  • Higher capacity, which will lead to a longer life.
  • Perfect for watches, heart monitor scans, and hearing aids.

Cons:

  • Takes more space

THE Final Verdict

Although these batteries are very similar, yet their thickness was crucial for our decision. Although more thickness will require more space, and you will probably have trouble putting the battery in the unit, it will still have many benefits. Thanks to it, your battery will have more capacity, power, and more durability, so it is clear that our choice is cr2032.
