Rechargeable Lithium 18650 Cell Voltcraft VC-18650PCM 3.6V 3400mAh

Voltcraft VC-18650PCM is a rechargeable lithium 18650 cell with a nominal voltage of 3.6 V and a rated capacity of 3400 mAh. Engineered for applications requiring compact, high-energy cells, this battery provides steady discharge characteristics and is suitable for incorporation into single-cell devices or multi-cell battery packs when combined with appropriate protection electronics. The cell is intended for devices such as flashlights, portable electronics, power banks and custom battery assemblies where reliable runtime and consistent voltage are required.

Advantages

The cell offers a high energy density in the standardized 18650 format, enabling extended runtime compared with lower-capacity cylindrical cells. Stable voltage during discharge supports consistent device performance. Its rechargeable chemistry allows for many charge/discharge cycles when used with proper chargers. The standard size and form factor simplify integration into common holders, tubes and pack constructions for DIY or replacement purposes.

Suitable for

• Handheld flashlights and tactical lights
• Portable electronics and USB power banks (with appropriate circuitry)
• DIY battery packs and custom power assemblies
• Rechargeable replacements for compatible 18650 battery compartments

Key specifications

• Cell type: lithium-ion rechargeable, cylindrical 18650 format
• Nominal voltage: 3.6 V
• Rated capacity: 3400 mAh
• Typical use: single-cell devices or multi-cell packs with protection
• Form factor: 18 mm diameter × 65 mm length (standard 18650 dimensions)

How to use

Install the cell observing correct polarity and ensuring proper mechanical contact in the device or holder. For single-cell devices, use a charger and charging profile appropriate for 3.6 V lithium-ion chemistry and stop charging when the charger indicates a full charge. When building multi-cell packs, include a suitable protection circuit module (PCM/BMS) to prevent overcharge, over-discharge and overcurrent. Do not attempt to use this cell in equipment requiring different chemistries or voltages without appropriate conversion and protection circuitry.

Usage recommendations

Use a dedicated lithium-ion charger with the correct charge termination and temperature monitoring. Store cells partially charged (around 40–60%) for long-term storage and avoid exposing them to extreme temperatures or mechanical damage. Replace cells that show signs of swelling, leakage or significant capacity loss. Always follow device manufacturer guidelines and applicable safety standards when assembling or replacing batteries.
