Why Specify Our CR2477? Unrivaled Power and Endurance
1. Colossal Energy Density (1000mAh)
At 7.7mm thick, the CR2477 maximizes internal volume to house an incredible 1000mAh capacity. This is roughly five times the energy of a standard CR2032. For devices that draw higher pulse currents or require a decade-long standby life, this battery stands alone at the top of its class.
2. Rugged Thermal Resilience (-20°C to 70°C)
Industrial environments are unforgiving. Whether installed in a freezing logistics terminal or a hot manufacturing plant, our advanced chemical formulation guarantees a stable, uninterrupted voltage supply across a demanding temperature range of -20°C to 70°C.
3. Ultra-Low Self-Discharge (<2% Annually)
True reliability means being ready when called upon, even years down the line. Featuring premium lithium purity and a state-of-the-art leak-proof seal, the CR2477 boasts a self-discharge rate of less than 2% per year. Store them in bulk with absolute confidence.
4. Exacting Dimensional Standards (Φ24.5 × 7.7mm)
Precision is everything in hardware manufacturing. Manufactured to flawless global tolerances, this robust cell ensures perfect contact in standard CR2477 PCB mounts and battery holders, preventing micro-disconnects in high-vibration industrial settings.

Core Application Ecosystems
Because of its extraordinary energy reserves, the CR2477 is the battery of choice for applications where accessibility for replacement is difficult, expensive, or impossible. It excels in:
Industrial Control Boards: The ultimate RTC (Real-Time Clock) and memory backup solution for PLCs, CNC machinery, and embedded automation systems.
Point of Sale (POS) Terminals: Providing years of uninterrupted power to safeguard encryption keys and merchant data in high-security commercial payment systems.
Notebooks & Rugged Laptops (NB): Functioning as an ultra-long-life CMOS battery for ruggedized field computers and industrial motherboards, preserving BIOS and system integrity.
Active RFID & Asset Tracking: Powering logistics tags and beacons that need to transmit data over long periods without battery swaps.

Expert FAQ: Sourcing the CR2477
Q: What makes the CR2477 different from the CR2450? A: While both have a diameter of 24.5mm, the difference is in the height and capacity. The CR2450 is 5.0mm thick with a ~600mAh capacity. The CR2477 is significantly thicker at 7.7mm, allowing it to house a massive 1000mAh. It is specifically designed for devices requiring absolute maximum battery life. (Note: Ensure your device's battery holder is designed for a 7.7mm depth).
Q: Why is the CR2477 preferred for Industrial Controls ? A: In industrial settings, the labor cost to shut down a machine, open a control panel, and replace a backup battery far exceeds the cost of the battery itself. The CR2477's 1000mAh capacity and ultra-low self-discharge (<2%) often allow it to outlast the operational lifespan of the machinery itself, making it a zero-maintenance component.
Q: Does this battery suffer from voltage drops in cold weather? A: Our CR2477 utilizes a specialized Li-MnO2 chemistry that maintains excellent voltage stability even at -20°C, ensuring that field equipment and remote sensors stay online during winter or in cold-storage facilities.
