Regarding button cell battery, I believe everyone is no longer unfamiliar with this term.

We can often find the shadow of button batteries in cameras, watches, calculators, and so on. Button cell batteries play a dominant role in various electronic digital and home improvement fields by virtue of their "compact body".

Button batteries are prevalent because of their small footprint, lightweight, long-lasting power supply, and ease of use. In addition to the well-known advantages, we should also understand the classification of button cell batteries.


 

Appearance

Button cell batteries, also known as coin cell batteries, are batteries with a shape and size like a small button, generally larger in diameter and thinner in thickness. In terms of appearance, the equivalent corresponding battery classifications are cylindrical batteries, square batteries, special-shaped batteries, etc.

 

Chemical Cell Batteries & Physical Cell Batteries

Button cell batteries can be divided into two categories: chemical cell batteries and physical cell batteries.

Button batteries with chemical composition are most popular in our daily life. They are composed of anode, cathode, and electrolyte. The chemical composition of batteries is often carbon, alkaline, zinc-silver oxide, zinc-air, lithium-manganese dioxide button batteries, etc.

 

Rechargeable & Non-rechargeable Button Cell Batteries

Button batteries can be divided into rechargeable and non-rechargeable. 3V CR series, 1.5V LR series, etc. are usually non-rechargeable button cell batteries. The rechargeable button cell batteries normally include the 3.6V LIR series, 3V ML series, VL series, and so on.

For the disposable button battery, we use it immediately and throw it away after use. Some types of button cell batteries can be recharged and put into use again, which is conducive to reducing the use of waste and reducing environmental pollution.

I believe that you have a simple understanding of button cell batteries. If you have a lot of electronic products that use button batteries, you may wish to buy some more in case you need them from time to time.

The use of button cell batteries is to select the proper type of battery suitable for the corresponding environmental characteristics according to the actual situation. It does not discard and makes reasonably recycled after use.
