What is a CR2450 Battery?

The CR2450 battery is a specific type of primary lithium coin cell battery. The ‘CR’ designation indicates its chemistry: a primary (non-rechargeable) cell with a manganese dioxide cathode and a lithium anode. The ‘2450’ refers to its dimensions: approximately 24.5 mm in diameter and 5.0 mm in thickness. These batteries are known for their high energy density, long shelf life, and stable voltage output, typically around 3 volts.

These coin cells are hermetically sealed to prevent leakage and ensure safety and reliability. Their robust construction and stable chemistry make them suitable for a wide range of applications where long-term, dependable power is required from a compact form factor. They are widely used in devices like car key fobs, small remote controls, digital scales, calculators, medical devices such as glucose meters, and various small electronic gadgets.

CR2450 Battery Specifications Explained

Understanding the specifications of a CR2450 battery is essential for selecting the correct power source for a device. The key characteristics include:

• Chemistry: Lithium-Manganese Dioxide (Li-MnO2). This provides a high energy density and excellent performance.
• Voltage: Nominal 3.0 Volts. This higher voltage is a key advantage over lower-voltage alkaline button cells.
• Dimensions: 24.5 mm diameter x 5.0 mm height. This standard size ensures compatibility with many devices.
• Capacity: Typically around 550-650 mAh (milliampere-hours), indicating the amount of charge the battery can deliver over time. This varies slightly between manufacturers.
• Operating Temperature: Generally rated for a wide temperature range, often from -20°C to 70°C (-4°F to 158°F), making them suitable for various environments in Malaysia.
• Shelf Life: Excellent long shelf life, often exceeding 10 years due to minimal self-discharge.

Common Applications for CR2450 Batteries in Malaysia

In Malaysia, CR2450 batteries are powering a variety of essential small electronics. Car key fobs are a prime example, ensuring drivers can easily access and start their vehicles, a necessity in bustling cities like Kuala Lumpur and George Town. Small remote controls for home entertainment systems, garage door openers, and even some advanced security system components rely on the consistent power these batteries provide.

Medical devices also frequently utilize CR2450 batteries due to their reliability and long life. Digital thermometers, glucose meters, and pulse oximeters often require a stable power source that doesn’t need frequent replacement. In the commercial sector, CR2450 batteries can be found in small electronic measuring tools, remote sensors for inventory management, and even some types of electronic shelf labels in retail environments across Malaysia. Their compact size and high energy output make them ideal for miniaturized electronics.

• Automotive: Key fobs, tire pressure monitoring systems (TPMS).
• Home Electronics: Small remote controls, wireless doorbells, calculators, electronic locks.
• Health & Fitness: Glucose meters, digital thermometers, heart rate monitors, pedometers.
• Security: Small wireless sensors, panic buttons, personal safety alarms.
• Office & Tools: Laser pointers, small measuring devices, electronic tags.

CR2450 vs. Other Coin Cell Batteries

The CR2450 battery offers distinct advantages over other common coin cell types, particularly alkaline variants like the CR2032 or LR44. Its larger diameter and thickness allow for a greater amount of lithium and cathode material, resulting in a higher capacity and longer service life. The 3.0V lithium chemistry provides a more stable and higher voltage output compared to the 1.5V of alkaline button cells.

While other lithium coin cells like the CR2016, CR2026, or CR2032 share the same lithium-manganese dioxide chemistry, the CR2450’s larger size translates directly into more power and endurance. This makes it the preferred choice for devices that drain batteries faster or where replacement is inconvenient. In Malaysia, selecting the correct coin cell is vital; always check the device’s manual or the existing battery for the exact model number.

Market Trends and Availability in Penang, Malaysia (2026)

The market for CR2450 batteries in Malaysia is robust, driven by the continuous demand from the electronics and automotive sectors. As smart home technology and wearable devices become more prevalent, the need for compact, reliable power sources like the CR2450 continues to grow. Manufacturers are focusing on improving energy density and ensuring consistent quality across their product lines. Availability is generally widespread, with major brands accessible throughout the country.

In Penang, a significant hub for electronics manufacturing and technological development in Malaysia, the demand for CR2450 batteries is particularly strong. Local manufacturers and assembly plants rely on a consistent supply of these components. Consumers in George Town and across the island can find these batteries readily available in electronics shops, supermarkets, and convenience stores. Choosing reputable brands is advisable to ensure performance and safety.

Branded batteries from established manufacturers like Panasonic, Energizer, or Duracell generally command a higher price but offer greater assurance of quality and performance. Generic or unbranded options might be cheaper but can vary significantly in quality and lifespan.

When purchasing CR2450 batteries in Malaysia, especially in areas like Penang, it’s advisable to buy from trusted retailers, either online or in physical stores, to avoid counterfeit products. Checking the expiry date is also important, as batteries stored for too long may lose their charge. For bulk purchases, particularly for businesses, sourcing from authorized distributors can ensure competitive pricing and product authenticity.

Safety and Handling of CR2450 Batteries

CR2450 batteries, like all lithium coin cells, require careful handling to ensure safety. They are designed for low-drain devices and should not be used in applications that demand very high current, as this can lead to overheating or leakage. Never attempt to recharge a CR2450 battery, as it is a primary cell and recharging can cause it to rupture or explode.

Avoid exposing CR2450 batteries to extreme temperatures, fire, or short-circuiting the terminals. While reputable manufacturers build in safety features, misuse can compromise these protections. Always use the specific battery model recommended by the device manufacturer to ensure optimal performance and safety. For those in Malaysia, purchasing from authorized channels helps ensure product safety and compliance.

Environmental Impact and Disposal in Malaysia

CR2450 batteries contain lithium and other materials that require responsible disposal. While they are sealed and generally safe, discarding them in regular household waste can lead to environmental contamination if they end up in landfills. Many countries, including Malaysia, have established battery recycling programs or designated collection points for small electronics and batteries.

The long shelf life and stable performance of CR2450 batteries mean they often last for many years in devices, reducing the frequency of replacements compared to lower-quality alternatives. This extended lifespan can contribute positively to reducing overall battery waste. However, responsible end-of-life management remains crucial for minimizing the environmental footprint of these small but essential power sources.
