Button Rechargeable Batteries

Button rechargeable batteries are small, flat, disc-shaped cell batteries. They are widely known as coin cell batteries, coin batteries, or button cells. These rechargeable batteries come in a wide range of voltages and sizes, including the popular 3V lithium coin cell, among other types of batteries. They are generally used to power small portable electronic devices like digital watches, hearing aids, and remote controls, where their compact size and longevity are beneficial.

What are button rechargeable batteries used for?

Button rechargeable batteries are typically used to power small portable electronic devices. Their small size, combined with the versatility of being rechargeable, makes them ideal for applications requiring long service life and high energy density. The unique properties of the coin cell battery also make them particularly suited for use in sensitive medical devices and critical backup systems.

Wristwatches (analogue and digital): These devices require reliable, continuous power in an extremely compact form factor. The button cell battery fits neatly into the watch case, providing long-term operation for both timekeeping and digital displays.
Pocket calculators and LED torches: Button rechargeable batteries are commonly used in handheld devices. The battery's steady power output ensures accurate calculations and consistent light emission from LED torches and other portable lighting equipment.
Remote controls and toys: The ability to recharge is a key benefit here, as these devices are frequently used. Rechargeable button batteries reduce waste and offer a dependable, cost-effective power source for toys and domestic remote controls.
Hearing aids and Medical Devices: Due to their long service life, they are particularly suited for critical medical uses, such as pacemakers, surgical lighting, and glucose monitors. The compact cell battery is ideal where regular replacement is difficult or hygiene is paramount.
Backup power for mains-operated systems: Like other forms of rechargeable batteries, they are a dependable choice for providing immediate power to back up equipment that is normally mains-powered in case of a power failure.

Advantages of coin button rechargeable batteries

Compared to disposable coin cells, rechargeable button batteries offer substantial benefits in longevity, sustainability, and operational versatility. The fact that they can also be recharged makes them all the more versatile, allowing for prolonged use even in high-powered devices like hearing aids.

Extended Service Life: Designed for repeated charge cycles, reducing the need for frequent replacement. Rechargeable button batteries are ideal for applications where replacing a battery is difficult or expensive, such as in pacemakers.
Compact and Efficient: Ideal for designs with limited space, ensuring stable 3V voltage output even in miniature devices. The small size and compact nature of the coin cell design optimise power delivery in tiny electronics.
Cost-effective and Sustainable: Being rechargeable makes them reusable over time, significantly reducing waste compared to single-use cells, supporting eco-friendly product design.
Reliable Performance: The 3V lithium coin cell chemistry maintains consistent capacity and voltage throughout the discharge cycle. Such reliable performance suits both consumer and industrial-grade electronics, ensuring a stable power supply.

Industrial Applications of Button Rechargeable Batteries

Button rechargeable batteries are highly valued for their compact size and reliable voltage, making them essential components in diverse industrial and critical low-power applications across Australia.

Medical Devices

Critical medical devices, such as implantable pacemakers and glucose monitors, rely on the stable power provided by rechargeable coin cells. The 3V lithium coin cell is chosen for its long service life, ensuring dependable operation where regular battery replacement is difficult or invasive.

Industrial IoT and Sensor Technology

Industrial IoT deployments and remote sensor networks utilise button cells for long-term power. These rechargeable batteries are ideal for asset tracking tags, environmental sensors, and small data loggers that need a compact, stable 3V supply in remote or industrial settings.

Security and Safety Systems

Button rechargeable batteries serve as reliable backup power for security systems, access control key fobs, and emergency beacons. The coin battery's low self-discharge rate ensures systems remain dormant yet ready for activation over extended periods in safety-critical applications.

Specialised Electronics and Computing

The button cell is used in specialised electronics for real-time clock (RTC) backup in servers and communication equipment. The small form factor makes the rechargeable coin cell suitable for maintaining crucial memory settings during temporary power loss or shutdown procedures.

Automotive Electronics

The automotive sector uses rechargeable button batteries in applications requiring robust, long-lasting power in a confined space. They are found in keyless entry fobs, remote control systems, and specialised sensors like Tyre Pressure Monitoring Systems (TPMS), where stable voltage and resistance to vibration are crucial.

Consumer Wearables

The growing wearables market depends on rechargeable coin cell technology for its compact design. Fitness trackers, smart watches, and specialised electronic jewelry utilise these batteries for high energy density, allowing devices to maintain long operational periods between charges.
