Protected 18650 Lithium-Ion Battery

Jauch Quartz protected 18650 Li‑Ion batteries are engineered to provide reliable and long‑lasting power for demanding applications requiring both high energy density and robust safety performance. With a nominal voltage of 3.6 V and a typical capacity of 3,350 mAh, the cell offers an excellent balance of endurance and efficiency, making it suitable for professional devices across industrial, medical, and portable electronics environments. Its compact cylindrical design and approximate weight of 50 g make it effortless to integrate into tightly constrained assemblies without compromising on output or operational stability.

Built with a comprehensive protection circuit module (PCM), this battery provides multi‑layer safeguarding against overvoltage, undervoltage, short circuits, and excessive current flow. The overcharge detection voltage is precisely regulated at 4.30 V ±0.05 V, while the discharge cut‑off voltage of 2.5 V ensures cell longevity and stable performance. The battery supports a standard charging current of 670 mA, with a maximum charge current of 1,005 mA, and can safely deliver discharge currents up to 5,000 mA within its recommended temperature range. Its operational window extends from -20°C to +55°C, ensuring reliable functionality in diverse environmental conditions. Built‑in PTC protection further enhances safety by providing thermal and overcurrent interruption when required.

Jauch ensures that the protected 18650 Li-Ion battery fully complies with international safety and environmental standards. The cell is RoHS compliant, REACH compliant, 100% lead‑free, and free from conflict minerals, reflecting the commitment from Jauch to ethical manufacturing and environmentally responsible sourcing. Its certifications, including UL1642/UL2054, UN38.3, and IEC 62133‑2, reinforce its suitability for integration into regulated product designs where stringent safety verification is mandatory. Combined with rigorous quality‑assurance processes, this battery provides a dependable and high‑performance solution for applications where continuous safety and long‑term reliability are critical.
