What Is a LIR1254 Button Cell Battery?

Have you ever noticed battery models like CR2032, LIR1254, or LR44 in our daily life? They are called button or coin cell batteries. They are popular in electronic devices because of their small size and people use them as backup power for various types of electronics, such as watches, key fobs, remote controls, toys, hearing aids.

What does the “CR" or “LIR" mean?

In fact, it’s the IEC 60086-3 international standard which defines the name. According to the standard, CR usually means round-shaped lithium-manganese dioxide battery. Among, “C” refers to the chemical composition of the battery, specifically lithium-manganese dioxide (LiMnO2). This indicates the type of chemistry used inside the battery, which provides high energy density and long shelf life. “R” refers to the round or cylindrical shape of the battery, typically used for coin or button cells. The standard only describes primary batteries. The following are some common models.

Rechargeable types made in the same case size will carry a different prefix not given in the IEC standard, for example some ML and LIR button cells use rechargeable lithium technology. The LIR stands for Lithium Ion Rechargeable, and sometimes called “rechargeable CR". Rated at 3.7V, the voltage of LIR battery is higher than CR, and can cause damage when used as direct replacement, may be lowered with a serial diode or regulator.

What does the number “2032" or “1254" mean?

The number after the letter represents the size of the coin cell. For example, the popular CR2032 is a Lithium Button Cell Battery with a diameter of 20mm and a height of 3.2mm. The LR44 is an Alkaline button cell battery with a diameter of 11mm and a height of 5.4mm. The LIR1254 has a nominal voltage of 3.6 to 3.7 volts when fully charged. The “1254″ in the name refers to its standard size, with a diameter of 12mm and a height of 5.4mm, which is the same size as non-rechargeable CR1254 lithium coin cell batteries.

What is a LIR1254 button battery?

As mentioned above, LIR1254 is a kind of rechargeable lithium button cell battery that is 12mm diameter x 5.4mm thickness. LIR1254 batteries use a lithium-ion chemistry, which means they are rechargeable. They contain a lithium cobalt oxide or similar lithium-ion chemistry in their positive electrode (cathode) and lithium in the negative electrode (anode). These batteries can be recharged and reused multiple times. LIR1254 batteries have a nominal voltage of 3.6 to 3.7 volts when fully charged. This voltage remains relatively constant during discharge.

What are the applications of LIR1254 button battery?

The LIR1254 battery is typically used in applications requiring compact and rechargeable power sources. Common uses include powering small wearables, portable medical equipment, IoT devices, and wireless communication systems. Other popular 12mm diameter button batteries include LIR1224, LIR1240, and LIR1250. Their thicknesses are 2.4mm, 4.0mm, and 5.0mm respectively. Below are their common applications.

  ●LIR1224: Typically used in devices like smoke consumer electronics, wearables, medical devices, cameras and computer components.

  ●LIR1240: Commonly used in backup power for digital cameras, handheld gaming devices, and some medical equipment that requires a reliable energy source.

  ●LIR1250: Typically used in devices like smoke detectors, toys, and automotive applications (like keyless entry systems) that need a dependable power source for continuous operation.

Conclusion

In conclusion, the LIR1254 button cell battery exemplifies the blend of compact design and rechargeable technology, making it a vital component in various modern devices. Understanding its specifications, such as size and voltage, is essential for ensuring compatibility and optimal performance in applications ranging from wearables to IoT systems. By delving into the specifics of button cell batteries, users can make informed choices that enhance the longevity and functionality of their devices. As wearable technologies continue to evolve, the role of powerful, reliable, and efficient batteries like the Grepow rechargeable coin cell battery will undoubtedly expand, continuing to empower users and pave the way for future innovations in personal safety equipment.
