• Applications: Button cell batteries are commonly used in devices like hearing aids, small electronic toys, medical devices, and some watches.
• Voltage: Button cell batteries typically have a voltage ranging from 1.5 to 3 volts, similar to coin cell batteries.

Types of Coin and Button Cell Batteries

Alkaline Batteries

Alkaline coin and button cells are widely used due to their reliability and long-lasting performance. These batteries use an alkaline electrolyte, which allows for a stable voltage output. Common sizes include AG1, AG10, AG13, and others, with each size designated for specific devices. Alkaline batteries are commonly found in everyday electronics such as remote controls, toys, and small electronic gadgets. Their affordability and widespread availability make them a popular choice for many consumer applications.

Silver Oxide Batteries

Silver oxide coin cells are known for their high energy density and consistent voltage output throughout their lifespan. These batteries are commonly used in devices that require a steady power supply, such as watches, calculators, and various medical devices. Common sizes for silver oxide batteries include SR44, SR626SW, and SR927SW. The stable voltage of silver oxide batteries is crucial in precision instruments, ensuring accurate timekeeping and reliable performance in medical equipment.

Lithium Batteries

Lithium coin and button cells have gained popularity for their lightweight design, high energy density, and long shelf life. These batteries are commonly used in a wide range of devices, from key fobs and digital cameras to medical implants. Common sizes include CR2032, CR2025, and CR1632. Lithium batteries are preferred for applications that demand a compact and lightweight power source, and they are known for their ability to provide a stable voltage output over a more extended period compared to other types.

Zinc-air Batteries

Zinc-air coin and button cells operate by using oxygen from the air as a reactant, making them ideal for specific applications, such as hearing aids and some medical devices. Common sizes for zinc-air batteries include PR44 and PR675. These batteries are valued for their high energy density and long operational life, making them suitable for devices where frequent battery replacement may be inconvenient. The use of air as a reactant also contributes to their eco-friendly profile.

Applications

Watches

One of the most common applications of coin cell batteries is in wristwatches and other timekeeping devices. The small, disc-shaped batteries fit seamlessly into the limited space within a watch, offering a reliable and consistent power supply. Unlike traditional disposable batteries, coin cells can power watches for extended periods, ensuring accurate timekeeping without the need for frequent replacements.

Calculators

Handheld calculators have become an essential tool for students, professionals, and anyone in need of quick calculations. Coin cell batteries provide the energy needed to keep these devices running smoothly. Their compact size allows for a slim and lightweight design, making calculators easily portable while ensuring a long operational life.

Remote Controls

The convenience of controlling electronic devices from a distance owes much to coin cell batteries. Remote controls for TVs, air conditioners, and other gadgets often rely on the small, button-shaped cells to transmit signals efficiently. The consistent power output of coin cells ensures that remote controls remain responsive over time, reducing the hassle of frequent battery changes.

Medical Devices

In the realm of healthcare, coin cell batteries play a critical role in powering implantable medical devices. Pacemakers, for example, require a reliable and long-lasting power source to regulate the heart's rhythm. Coin cells meet these requirements, providing a compact and energy-dense solution that can sustain these life-saving devices for several years without the need for frequent interventions.

Key Fobs and Electronic Access Systems

Modern car key fobs and electronic access systems have become commonplace, offering convenience and security. Coin cell batteries power these devices, enabling compact and lightweight designs that easily fit into pockets or attach to keychains. The dependable performance of coin cells ensures that users can rely on their key fobs for an extended period between battery changes.

Choosing The Right Coin & Button Cell Battery

Selecting the appropriate battery for your particular device is crucial to guarantee peak performance and durability. This guide will examine the key considerations when choosing coin and button cell batteries.

Battery Size and Type

The first step in choosing the right battery is to identify the size and type required by your device. Common sizes include CR2032, CR2025, CR2016, LR44, and SR626SW. It's crucial to check the device's manual or the existing battery to determine the correct size and type.

Voltage and Capacity

Coin and button cell batteries vary in voltage and capacity. The voltage is a measure of electrical potential, and capacity refers to the amount of energy the battery can store. Ensure that the replacement battery has the same voltage and capacity as the original to maintain proper functionality.

Chemistry

Different coin and button cell batteries use various chemistries, such as alkaline, silver oxide, and lithium. The choice of chemistry depends on the specific requirements of the device. Alkaline batteries are suitable for low-drain devices, while silver oxide and lithium batteries are better for high-drain applications.

Shelf Life

Consider the shelf life of the battery, especially if you plan to buy in bulk for future use. Some batteries have a longer shelf life than others, ensuring they retain their charge while in storage.

Safety Considerations

• Child Safety: Coin and button cell batteries can pose a choking hazard for children. It's crucial to store these batteries safely, out of reach of young children.
• Swallowing Hazard: Ingesting coin cell batteries can lead to serious health issues. Parents and caregivers should be aware of the risks and seek immediate medical attention if ingestion is suspected.
• Disposal: Proper disposal of used batteries is essential. Many coin cells contain hazardous materials, and recycling facilities should be used to minimize environmental impact.
• Leakage: Batteries can leak corrosive materials if left in devices for extended periods. Regularly check and replace batteries to prevent damage.

Conclusion

Coin and button cell batteries play an essential role in powering numerous small electronic devices that enhance our daily lives.
