Batería recargable Feuerhand FH-18650-LI-ION — celda de litio-ion 18650

Feuerhand FH-18650-LI-ION is a rechargeable 18650 lithium‑ion cell engineered for devices and DIY battery packs that accept the 18650 form factor. The cell provides the standard performance characteristics of modern lithium‑ion chemistry, suitable for portable electronics, LED flashlights, and small power banks. It is intended as a direct-format replacement where capacity and voltage specifications of 18650 cells are required.

Advantages

The Feuerhand 18650 lithium‑ion cell delivers a balance of energy density and compact size that fits most 18650-compatible devices. Its rechargeable chemistry allows for repeated charging cycles, reducing the need for disposable cells. The standardized cylindrical form factor ensures compatibility with common holders, chargers, and battery pack assemblies designed for 18650 cells.

Suitable for

• LED flashlights and torches that accept 18650 cells
• Portable power banks and USB battery packs that use 18650 modules
• DIY battery pack builds and replacements for 18650-format devices
• Handheld electronics and tools designed around 18650 cells

Key specifications

• Cell type: Lithium‑ion cylindrical 18650
• Form factor: 18650 (18 mm × 65 mm standard dimensions)
• Rechargeable: Yes — designed for repeated charge/discharge cycles
• Nominal voltage: Standard lithium‑ion cell voltage (approx. 3.6–3.7 V)
• Intended use: Replacement cell for devices accepting 18650-format batteries

How to use

Install the Feuerhand 18650 cell in any device or battery holder that accepts 18650 cells, observing correct polarity. Use a charger compatible with 18650 lithium‑ion cells and follow the charger manufacturer’s instructions. Do not attempt to charge the cell in chargers intended for non-rechargeable batteries. For DIY battery packs, incorporate appropriate protection circuits (BMS or protection PCB) to manage charging, discharging, and cell balancing.

Recommendations

Store and charge the cell in a dry, ventilated area away from heat sources. Use chargers and holders rated for lithium‑ion 18650 cells, and replace cells that show physical damage, swelling, or abnormal heating. Follow local regulations for transport and disposal of lithium‑ion batteries.
