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.
