Why Specify Our CR2450? Engineering Uncompromised Reliability
1. Unmatched Power Density (600mAh)
At 5.0mm thick, the CR2450 is designed to pack a punch. Delivering an industry-leading 600mAh capacity, it holds nearly three times the energy of a standard CR2032. For product designers, this means fewer battery replacements, drastically reduced maintenance costs, and a superior end-user experience.
2. Thermal Stability for Extreme Environments (-20°C to 70°C)
From sub-zero smart locks on front doors to industrial meters baking in the summer sun, environment dictates performance. Our CR2450 utilizes a highly stable chemical formulation that guarantees continuous, stable voltage discharge across a punishing temperature range of -20°C to 70°C.
3. The "Store & Forget" Advantage (<2% Annual Self-Discharge)
Supply chain efficiency requires components that last. Utilizing high-purity lithium and advanced leak-proof sealing technology, our CR2450 boasts an incredibly low self-discharge rate of less than 2% per year. Whether they are on your warehouse shelf or inside a backup system, they retain their charge until the moment they are needed.
4. Precision Manufacturing (Φ24.5 × 5.0mm)
Built to exact global dimensional standards, this battery ensures a perfect, snug fit in standard CR2450 coin cell holders. Say goodbye to micro-disconnects and voltage drops caused by poor physical contact.

Expert FAQ: Sourcing the Right Coin Cell
Q: What is the primary difference between a CR2430 and a CR2450 battery? A: The difference lies in thickness and capacity. Both share the same 24.5mm diameter, but the CR2450 is 5.0mm thick compared to the CR2430's 3.0mm. This extra thickness allows the CR2450 to hold a massive 600mAh, making it ideal for devices that require significantly longer runtimes.
Q: Can this CR2450 withstand outdoor applications? A: Yes. The battery is engineered to operate flawlessly in temperatures ranging from -20°C to 70°C, making it highly suitable for outdoor smart meters, weather stations, and exterior smart home security devices.
Q: Is the CR2450 a rechargeable battery? A: No. The CR2450 is a primary (non-rechargeable) Lithium Manganese Dioxide battery. Its high 600mAh capacity and ultra-low self-discharge rate are designed to provide years of reliable power without the need for recharging.
