16340 Rechargeable C Batteries with 850mAh capacity

Product Specifications

Model	Capacity	Voltage	Weight	Size	Energy Density	Charge/ Discharge Rate	Internal Resistance
BP16340	850mAh	3.6V	20g	Φ16.8*H33.5mm	153Wh/kg	1/4C	≤80mΩ

Moderate Capacity (850mAh) — Delivers a minimum of 750mAh at 0.2C discharge, providing reliable power for compact devices.
4A Continuous Discharge — Supports discharge currents up to 4A (prolonged use above 4A is not recommended to preserve battery life).
Type-C Charging with Auto-Recovery — Integrated Type-C port supports 5V/420mA±50mA charging with auto-restoration protection.
Standard 16340 Size (Ø16.8mm × 33.55mm) — Classic cylindrical form factor ensures compatibility with most 16340 devices.
Low Internal Resistance (≤80mΩ) — Improves charge-discharge efficiency and reduces heat generation during high-current operation.
Broad Operating Temperature Range — Charging: 0°C to +45°C; Discharging: -20°C to +60°C for use in varied environments.
Comprehensive Safety Protections — Built-in PCB safeguards against overcharge (4.275V±0.05V), over-discharge (2.50V±0.075V), overcurrent (4.2–7A), and short circuits.
Compliant with National Safety Standards — Meets GB 31241-2014 safety requirements and RoHS environmental directives.
Ideal for Compact Medium-Drain Devices — Suitable for high-intensity flashlights, portable lighting, compact instruments, and other small devices requiring stable power.
