## Long description

Panasonic NCR18650B is a rechargeable lithium‑ion cell in the 18650 format with a nominal capacity of 3400mAh and nominal voltage of 3.7V. It is intended for devices and assemblies that require high capacity in a single cylindrical cell: flashlights, power banks, portable electronics, and other applications where long run time and stable voltage are important. The cell features typical 18650 dimensions and is compatible with devices designed to accept standard 18650 cells when used together with appropriate holder and protection circuitry.
Advantages
The NCR18650B offers a high nominal capacity of 3400mAh which translates to extended operating time compared with lower-capacity 18650 cells. It provides a stable nominal voltage of 3.7V under typical loads, ensuring predictable performance for electronics that rely on consistent supply. The cell is rechargeable and suitable for repeated charge/discharge cycles when used with correct charging methods. Its standard cylindrical format facilitates replacement and integration into existing 18650-compatible battery holders and packs.

How to use
Use the cell only in devices and chargers designed for 18650 lithium‑ion cells. Observe correct polarity when inserting into holders or packs. Charge the cell with a compatible lithium‑ion battery charger that provides appropriate charge algorithm and termination (constant current/constant voltage). Do not attempt to charge the cell in chargers meant for other chemistries. If assembling multi-cell packs, include appropriate battery management or protection circuits to balance cells and protect against overcharge, over-discharge, and short circuit.
Использование и уход
Store and operate the cell within manufacturer-recommended temperature ranges, avoid mechanical damage, and do not expose to fire or water. Replace the cell if it shows signs of swelling, leakage, excessive heat, or significant capacity loss.
