 Samsung INR18650-25R High-Rate Lithium-Ion Cell

Introduction: Key Specifications

he Samsung INR18650-25R high-rate lithium-ion cell delivers exceptional power density for demanding applications. ​

Featuring​ a 2500mAh nominal capacity (2450mAh minimum) and 3.6V nominal voltage, this industrial-grade battery excels in high-drain scenarios.

Most importantly, it supports 20A continuous discharge current—a critical 5C rate for sustained heavy-load use.

Core Features

1. 20A Continuous Discharge & 5C High-Rate Performance
   Designed for demanding applications, the INR18650-25R provides stable 20A continuous discharge (surface temperature ≤75℃) and peak 25A burst current (with thermal protection). Its discharge rate spans 0.2C to 10C (20A/2A), ensuring versatility across industries.
2. Fast Charging & High Efficiency
   Supports 4A rapid charging (CCCV mode) with a 60-minute full charge time. Low initial impedance (≤18mΩ) minimizes energy loss and enhances output stability.
3. Wide Temperature Tolerance & Longevity
   • Low-Temperature Performance: Retains 60% capacity at -20℃ and 75% at -10℃.
   • High-Temperature Resilience: 90% capacity recovery after 1-month storage at 60℃.
   • Cycle Life: Maintains ≥1500mAh (60% capacity) after 250 cycles, outperforming competitors.
4. Safety & Durability
   Complies with UN38.3 transportation standards and passes rigorous safety tests (overcharge, short-circuit, heating). Equipped with an insulating sleeve to prevent accidental short circuits.

Applications

• Power Tools: Drills, grinders, and other high-demand devices.
• Drones/RC Models: Combines burst power with extended runtime.

Backup Power: Reliable performance in extreme environments.
