The numbers linked with different batteries may be confusing for you. Therefore, we are going to eliminate some of the confusion by discussing the difference between the CR2015 and CR2032. We will also discuss the uses of each so you can get the best value for your money. Read on to find out more about the difference.


Both the batteries are known as button batteries and are used in different types of low power devices like toys, computers, calculators, and watches, to name a few. These button cells can be used interchangeably in compatible devices.

So what's the difference?

Although both the button batteries provide 3 volts, the difference lies in the thickness. The diameter of CR2025 is 20mm and thickness is 2.5mm. In the same way, the CR2032 is 3.2mm thick and features 20mm of diameter. The diameter is the most important thing when it comes to installing a battery in a device.


mAh is short for milliampere-hour. As far as batteries are concerned, this term refers to how long the battery can carry its power and how long it can power the device it is installed in before you need to replace it.

Generally, the CR2025 offers 165mAh of power while the other offers 225 mAh. Based on how often the device is used, you may want to opt for the right unit.


Some users choose a unit that fits well and works great, while others worry about specifics. Given below is a description of some popular brands and the battery details.

THE CR2025

Eunicell: this type features a pack of 5 and offers 150 mAh of power and a lifespan of up to 2 years.

CELEWELL: it comes in a pack of 5 and costs a bit more. However, it's an ideal choice for smart trackers as it has an mAh capacity of 170+.

Energizer: With an mAh of 163, this one can hold its power for as many as 8 years when stored.

THE CR2032

ExcellBattery: it comes in a pack of 4 and features a capacity of 225mAh.

LiCB: With a shelf life of 8 years and a power rating of 240mAh, this battery type is ROHS certified and free of mercury.

Energizer: It has a capacity of 240 mAh and lasts much longer. Just like CR2020, it comes in a pack of 5.

This was a basic difference between the two batteries. If you need to buy one, make sure you consider these differences. This way you will be able to make a much better decision based on your needs.


In short, there is not a big difference between the CR2032 and CR2020. Although a CR2032 offers a longer storage life, you may not enjoy this advantage at all times. The only big difference is the capacity, which is given in mAh. Therefore, what you need to do is get a full pack. This will save you money and you won't have to drive to the market to buy another battery.
