What is a CR2477 Battery?

The CR2477 battery is a non-rechargeable lithium coin cell battery, distinguished by its specific designation. The ‘CR’ prefix indicates it’s a lithium-based chemistry, known for its high energy density and long shelf life. The ’24’ signifies its nominal diameter of 24.5 millimeters, and the ’77’ denotes its approximate height in millimeters, making it a relatively substantial coin cell. This size contributes to its capacity, typically around 950-1000 mAh, providing a reliable power output of 3 volts.

Compared to other coin cells, the CR2477 offers a balance of size and capacity, making it a popular choice for applications that need more power than smaller batteries but still require a compact form factor. Its lithium chemistry also means it can operate efficiently in temperatures ranging from approximately -30°C to +60°C, a critical factor for devices used in various Canadian climates, from the cold winters of Manitoba to the warmer summers of British Columbia.

Key Applications of CR2477 Batteries

The versatility of the CR2477 battery allows it to power a wide array of electronic devices. Its robust energy output and long lifespan make it a go-to choice for applications where battery replacement is inconvenient or critical. These applications span across consumer electronics, automotive accessories, and specialized equipment.

Understanding CR2477 Battery Specifications

When purchasing CR2477 batteries, understanding their specifications is paramount to ensuring compatibility and optimal performance. Several factors differentiate one CR2477 battery from another, even though they share the same size designation. Paying attention to these details can prevent performance issues and extend the life of your devices.

Nominal Voltage and Capacity

As mentioned, CR2477 batteries typically operate at a nominal voltage of 3 volts. This consistent voltage output is crucial for sensitive electronics. The capacity, usually measured in milliampere-hours (mAh), indicates how much energy the battery can store. A higher mAh rating generally means a longer lifespan for the device. For CR2477 batteries, capacities typically range from 950 mAh to 1000 mAh, with some premium brands offering slightly higher figures.

Shelf Life and Storage

Lithium coin cells like the CR2477 boast an impressive shelf life, often lasting up to 10 years when stored correctly. This longevity is due to the stable nature of lithium chemistry and the sealed construction of the battery, which minimizes self-discharge. Proper storage involves keeping the batteries in a cool, dry place, away from direct sunlight and extreme temperatures, and ideally in their original packaging to prevent short circuits.

Operating Temperature Range

The ability of a CR2477 battery to function across a wide temperature spectrum is a significant advantage. While performance might slightly decrease at extreme cold or hot temperatures, they generally remain operational in conditions ranging from -30°C to +60°C. This resilience is vital for devices used outdoors or in environments with fluctuating temperatures, a common scenario across various Canadian provinces.

Brand Reputation and Quality

While all CR2477 batteries adhere to the same dimensional and voltage standards, the quality can vary significantly between manufacturers. Reputable brands often use higher-grade materials and employ stricter quality control measures, resulting in batteries with better capacity, longer shelf life, and enhanced safety features. Opting for well-known, trusted brands is advisable, especially for critical applications like medical devices or automotive systems.
