What’s the Difference, CR2032 batteries vs 2016 batteries?

CR2032 battery is a non-rechargeable lithium coin that is small in size, like the size of a button with a capacity of 240mAh and 3 volts.

CR2032 is flat and round with a diameter of 20mm and a thickness of 3.2. It’s used in different ways, like car key fobs.

is a flat, round battery and small in size like a button. It is non-rechargeable with a capacity of 90 mAh and 3 volts.

Differences between CR2016 and CR2032.

They are used in different ways. CR2016 is used in devices that don’t require much energy such as watches. These CR2016 batteries supply less power required by such devices. On the other hand, CR2032 is used in electronics that need more power, such as remotes, bank card readers, and computer motherboards.

CR2032 has a capacity of up to 240 mAh making it retain charge for a longer duration of up to 10 hours of use. CR2016 can retain the charge for about 6 hours.

They are also a slight difference in size. The CR2016 is 1.6 millimeters in thickness compared to CR2032 which is 3.2 millimeters thick. This may make it not completely interchangeable.


Similarities between 2032 and 2016 batteries

CR2016 and CR2032 can be used interchangeably because of the similarities. They are primary batteries, which means they are both non-rechargeable; once the batteries are used, they aren’t reused; they are thrown away. The components used to make them don’t allow them to be recharged.

Both CR2016 and 2032 have 3 volts versions. This makes them be used for almost a similar purpose, primarily for household products.

CR2016 and CR2032 are small in size, round, and flat. These characteristics make them almost identical and hard to distinguish in such a way that one may be confused for the other. When buying them, one needs to be very careful to avoid buying the wrong battery.

Similarities between CR2032, CR2016, and others (CR2025)

There are other batteries such as Cr2025 that can be used to work, like CR2016 and CR2032. The CR2025 will serve the purpose of comparing the batteries.

The CR2025 is also small in size making, and it serves the same purpose as CR2016 and CR2032 in small devices that require less power like calculators, security devices, clinical thermometers, and watches. They all share this one similarity of having 3 volts and thus can use them interchangeably.

Difference between CR2025, CR2016, and Cr2030.

These three batteries have different thicknesses, CR2032 has 3.2mm, CR2025 has 2.5mm, and CR2016 has 1.6mm. The thickness of a battery determines how long it retains the charge.

The capacity of these batteries differs; CR2032 has the highest capacity, which is up to 240 mAh. CR2025 has a capacity of about 160 mAh, while CR2016 has a capacity of 90 mAh. The higher the capacity, the longer it keeps a charge. CR2032 keeps charge up to about 10 hours.


Keep away from the child’s reach. Most of these batteries are small in size, making them put your child at risk of swallowing them.

The materials that are used to make these batteries are lead and lithium, which may be harmful to your health. Products made with lithium-ion can be lethal in a very short time, which is not good for health. If, by any chance, somebody swallows the batteries, it is good that they seek medical advice.

Additionally, the waste products from these batteries can be a threat to the environment. These waste products which are not well disposed of can pollute the environment.


If you want to choose a battery that can serve you need and meet your standard you have to think about the thickness and capacity. Why you need the battery should dictate the type of battery you should buy.

Button batteries are small batteries that have come to rescue us from the problem of having devices that require a small amount of energy.

You can check whether the item has a battery, remove and test the voltage. The battery voltage must be between 1.35 and 3 volts.
