What is the difference between 2032 and 2025 batteries?

In the world of batteries, there are many different types. There are even a few different sizes that can be confusing to figure out what the difference is between them all. This post will break down in detail everything you need to know about these two battery sizes and how they compare.

What is the difference between a 2032 battery and a 2025 battery?

There are many types of batteries, and they all have their own unique uses. Among these batteries are the CR2032 and CR2025 batteries. These batteries are known as 'watch battery' or button cell, a small single-cell shaped like a squat cylinder typically 5 to 25mm. We get to see these kinds of batteries in small size electrical devices such as wristwatches, hearing aid, and basic calculator.

These two batteries may look the same at first glance, with small size and rounded shape. But upon one closer inspection, you will notice that there are subtle differences in their specifications.

CR2025 and CR2032 are two types of coin cell batteries that have different thickness. For example, the CR2025 is 2.5mm thick while the CR2032 is 3.2mm thick, which leads to differences in weight (CR 2025 has 170mAh capacity with 0g whereas CR 2032 has 235 mAh capacity at 1 g) as well as power consumption (3V vs. 3v).

It's also worth noting that even the tiniest changes in thickness can make a significant impact on energy storage. This is why you should choose CR2032 since they last much longer than the other batteries with similar size and shape.

Can I use CR2025 battery instead of CR2032?

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

What are the pros and cons of CR2032 and CR2025 batteries?

PROS

CR2025 - The CR2025 battery is small in size, so it's easy to fit. It can be used for calculators and children's toys without the worry of spoiling its parts while storing or inserting them into a device.

CR2032 - CR2032 batteries are more energy-efficient than their predecessors. These types of batteries have a higher capacity and run time which makes them best for watches, hearing aids, heart monitor scans, or any other device that requires less power consumption over an extended period of use.

CONS

CR2025 - CR2025 batteries are popular small batteries that can fit in many devices. However, since they have less capacity and shorter duration than other types of batteries, CR2025's 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 that can 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 emergency or need. These make excellent watch batteries, calculator batteries, garage door opener battery replacements (for example), toy battery power sources, and pet collar accessories as well.

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.

Conclusion

CR2025 and CR2032 are very similar. They both have the same voltage (3V), diameter, and usage in gadgets like watches or calculators. However, they aren't identical - make sure you know which one is needed before purchasing.

Your decision to buy these batteries will depend on their capacity. But since they're very small and thin, you'll need to be careful - kids or pets may swallow them, or it could take hours for you to find one if lost. Make sure you keep an eye on your kids and pets, so they don't swallow these types of batteries.

When choosing a battery, you need to consider your purpose for using the device as well as how often do you use it. You also have to factor in the budget and make sure that whatever size of batteries is available should fit inside the storage compartment or space on your own equipment.
