CR2025 Vs CR2032 Batteries – Are They Interchangeable?

Today’s market offers a plethora of varied and distinct battery options. This article will provide an in-depth explanation of everything you need to know about the two types of coin cell batteries, namely: CR2032 and CR2025. These batteries are known as watch batteries or button cells, a small single-cell shaped like a squat cylinder typically 5 to 25mm. We see these kinds of batteries in small-sized electrical devices such as wristwatches, hearing aid, and basic calculator.

Are CR2025 and CR2032 the same?

These two batteries may look the same at first glance, but they have subtle differences in their specifications. The difference between cr2025 and cr2032 is that CR2032 can deliver 225mAh with a thickness of 3.2mm, while the CR2025  only delivers 160mAh with a thickness of 2.5mm. Its thickness can significantly impact on energy storage. With that said, you should opt for CR2032 since they have a much longer lifespan than other similar-sized batteries.

Can I use a 2032 battery instead of a 2025?

The most frequent question is can you use cr2025 instead of cr2032 or vice versa. CR2025 and CR2032 can be used interchangeably in the battery compartment, with only minor impact, as long as either one fits. However, because it has a higher capacity (mAh), we expect that the CR2032 will last slightly longer than the other.

If you don’t have any other choice but to use a CR2025 battery on your device, one helpful tip is to fold up some aluminum foil and place it on top of the extra 0.7mm open space. Ensure good contact by closing your device, so it holds this piece of foil properly. Otherwise, there is a risk of intermittent connections between the spring contacts and your battery which can cause issues.

Battery 2025 vs. 2032: What are the pros and cons?


  • CR2025 – The CR2025 battery is small, so it’s easy to fit. It can be used for calculators and children’s toys without worrying about spoiling its parts while storing or inserting them into a device.
  • CR2032 – CR2032 batteries are more energy-efficient than their predecessors. These batteries have a higher capacity and run time, making them best for watches, hearing aids, heart monitor scans, or any device that requires less power over an extended time.


  • CR2025 – CR2025 batteries have less capacity and shorter duration than other types of batteries. Thus, CR2025 may not be ideal for all applications.
  • CR2032 – CR2032 batteries are a bit larger than normal, which is a disadvantage for small devices that don’t have the space to fit them.

Which is the best CR2032 battery?

If you are looking for a basic CR2032 battery that can run low-power electronics, then the AmazonBasics 4-pack is your best bet.

If you are up to some battery that can withstand different weather and hold power for up to 10 long years of storage, then Energizer’s CR2032 is your top choice as these can deliver high performance and value at the same time.

Sony sells a 10-pack of batteries that is cheaper than most in the market. However, they are not as long-lasting or efficient. They have a decent lifespan and are perfect for low-power devices like fitness trackers and garage door openers.

When you’re looking for a budget-friendly value grab, Panasonic’s CR2032 3V lithium manganese-dioxide coin cell batteries are where it’s at. Each contains five high-capacity button batteries on each card and comes in handy with fitness equipment, key FOBs, healthcare devices, and more.

These LiCB CR2032 batteries are rigorously tested for quality control and have a high grade. They also have a three-year shelf life, making them great to keep on hand in case of emergencies. These make excellent watch batteries, calculator batteries, garage door opener battery replacements (for example), toy battery power sources, and pet collar accessories.

Additionally, Duracell CR2032 batteries are known for a positive reputation among consumers and have a good track record for dependability. Customers loved these batteries because they’re easy to use, reliable, and long-lasting.

Are CR2032 and CR2025 Batteries Interchangeable?

The CR2025 and CR2032 can be used interchangeably with minimal effect, although the newer version will probably last slightly longer because it has a higher capacity (mAh).


CR2025 and CR2032 are functional to run our wristwatches, hearing aid, and basic calculator. They have the same voltage (3V) and diameter. However, your decision to buy these batteries will depend on their capacity and purpose. The battery should fit inside the storage compartment or space on your equipment. They’re tiny and thin, so you need to be careful as kids or pets may swallow them, or it could take hours to find one if lost.
