What Is a Button Cell Battery?

Also known as a coin cell or watch battery, a button cell battery looks like a circular and stainless steel disc that generates power for portable devices such as computers and watches. These batteries are pretty small and are often crucial for computers as they help these machines retain their system setting even if they are off. Besides, they are also found in many toys, watches, and toys that you use on a daily basis.

Comparing Different Button Cell Batteries: LR44, AG13, LR1154 and More

Most button cell batteries consist of lithium, alkaline, or silver oxide. Moreover, they can last for many years, provided you use them with care.

A button cell battery often has a diameter between five and 25mm. Further, its height varies between one and six mm.

What’s more, a coin cell battery comes with two terminals. There is a positive terminal made of stainless steel and is adjusted at the battery’s bottom. On the other hand, a negative terminal forms the battery’s top cap and is entirely insulated.

One of the most appreciated characteristics of button cell batteries is their longevity. These batteries have a low self-charge feature, meaning they can stay charged for an extended duration. This is why they are pretty popular.

Four Categories of Button Cell Batteries

Interestingly, there are four primary categories of button cell batteries. Below we have explained each type in detail.

Alkaline Battery

These batteries are the same size as other options, but these batteries offer less silver oxide and lithium batteries when it comes to voltage and capacity. Both LR44 and LR1154 are alkaline batteries.

Silver-oxide Battery

This category of button cell batteries has a stable discharge. You may find them in most precision devices and medical instruments. For instance, SR44 is a silver-oxide button cell battery.

Mercury-oxide Battery

Although it has a stable discharge, this battery isn’t used anymore because of its lethal and toxic nature. Unfortunately, this battery can be a massive reason behind air pollution when disposed of correctly.

Zinc-air Battery

Labeled as the “next-generation batteries,” a zinc-air battery has a much higher capacity than other options. Also, it comes with safety mechanisms and a high potential to hold more energy. Moreover, the cost per unit of this battery is pretty low.

What Is the Electrochemical System?

This term defines a cell that uses more than one electrode. It features an IEC 60086-3 standard that helps define these cells through unique alphanumeric codes.

For instance, alphabets C, S, and L are alphabets used for lithium, silver, and alkaline batteries, respectively. These batteries are primarily used in watches and small devices. Alternatively, the alphabet P represents zinc-air batteries used in hearing aids and medical instruments.
