## Long description

Panasonic NCR18650B is a rechargeable 18650 lithium‑ion cell with a nominal voltage of 3.7 V and a rated capacity of 3400 mAh. Engineered for high‑capacity, single‑cell applications, this cylindrical cell provides steady voltage output and extended runtime compared with lower‑capacity 18650 variants. It is intended for use in devices that accept standard 18650 format cells and where appropriate battery management or protection is provided.
Advantages
The Panasonic NCR18650B offers a high energy density relative to its size, enabling longer operation between charges in compatible devices. Its consistent nominal voltage supports stable performance for electronics sensitive to voltage swings. The cell is rechargeable and designed for numerous charge cycles when charged and stored according to manufacturer recommendations. As a commonly used 18650 format, it is compatible with a wide range of holders, battery packs, and chargers that support standard lithium‑ion cells.
Suitable for
 High‑capacity flashlights and portable lighting
 Power banks and DIY battery packs (with proper protection)
 Vaporizers and personal electronics designed for 18650 cells
 Portable tools and small appliances requiring 3.7 V nominal cells
Key specifications
 Cell type: cylindrical lithium‑ion (18650 form factor)
 Nominal voltage: 3.7 V
 Rated capacity: 3400 mAh
 Chemistry: lithium‑ion (high‑capacity cathode)

 Typical applications: single‑cell devices, battery packs with BMS
How to use
Install the cell in devices designed for 18650 lithium‑ion batteries or in battery holders and packs that provide appropriate mechanical support and electrical connections. Use chargers specifically designed for lithium‑ion cells and follow the charger manufacturer’s instructions. When building battery packs, include proper battery management systems (BMS) or protection circuits to prevent overcharge, overdischarge, and short circuits. Do not attempt to modify the cell or use it in equipment that is not rated for lithium‑ion chemistry or the 18650 form factor.
Usage recommendations
Store and charge the Panasonic NCR18650B in accordance with safe lithium‑ion practices: avoid exposure to high temperatures, do not puncture or crush the cell, and do not leave charging unattended for extended periods. For optimal lifespan, store cells at partial charge (around 30–50%) if they will not be used for long periods, and use a compatible charger and protection circuit during operation.
