Comparatively, CR2032 has a higher battery capacity of 240mAh. That’s a difference of 70mAh!

3. Weight

Another physical difference between the batteries is weight. The CR2025 battery weighs 2.6 grams, whereas the CR2032 battery weighs 3.0 grams.

Of course, the weight might differ slightly depending on the manufacturer. But the general difference between both of them is about 0.4 grams. So, CR2025 is a thinner battery.

4. Durability

The lifespan of a button cell battery depends on various different factors. These include material quality, temperature, storage conditions, and usage intensity.

Ideally, a high-quality button cell battery that is stored in a dry and cool place will last anywhere from 3 to 10 years. The average for lithium batteries is around 4 to 5 years.

However, if the usage is intense and frequent, the CR2025 battery will last 1 to 3 years. Meanwhile, the CR2032 battery can pull out a longer service life – thanks to its higher capacity.

5. Use

As lithium cell batteries, both types are versatile and multi-purpose. It doesn’t matter whether they are big or small. You can install them on all kinds of devices like laser pens, wristwatches, fitness appliances, etc.

But, the CR2032 has certain limitations due to its thickness. You cannot use it in gadgets that have a small or thin mounting space.

For such gadgets, a CR2025 battery will work much better. It will slip in and out easily. Also, the gadget will remain safe and undamaged.

However, since the CR2032 has a higher battery capacity, you can use it for more powerful devices like hearing aids, LED lights, and security devices.

6. Cost

Button batteries come in individual packages. People can buy one or two depending on their requirements. This makes the battery generally expensive.

But, when shopping, you will observe that the CR2032 battery is slightly more expensive than the CR2025. It’s mainly because the battery has the potential to power larger devices.

Table of Main Differences
