## Long description

Rechargeable 18650 Li‑Ion cell AVACOM NCR18650B with nominal capacity 3400mAh and nominal voltage 3.7V. The cell is intended for devices that accept standard 18650 batteries, offering extended runtime and consistent discharge behavior within its nominal voltage range. It is a single cylindrical cell without integrated protection circuitry, so a compatible charger and appropriate handling are required for safe charging, discharging and storage.
Advantages
The AVACOM NCR18650B delivers a high nominal capacity of 3400mAh in the common 18650 form factor, enabling longer operating times compared with lower‑capacity cells. With a nominal voltage of 3.7V it provides stable power output for devices designed for Li‑Ion chemistry. The cell's standard dimensions make it compatible with many flashlights, power banks, e‑cigarettes and portable electronics that accept unprotected 18650 cells.

How to use
Insert the cell into devices that accept 18650 cylinders observing correct polarity. Charge only with chargers compatible with Li‑Ion chemistry and with appropriate charge termination (CC/CV). If assembling battery packs or using multiple cells, ensure cells are matched by capacity and state of charge and include a suitable battery management system or protection circuit. Do not use the cell in devices requiring a protected cell unless external protection is provided.
Usage recommendations
Store and charge the battery in a ventilated, dry area at moderate temperatures; avoid exposure to extreme heat, fire, or water. Do not short‑circuit, puncture, crush or disassemble the cell.
