Safety Guidelines & Warnings
⚠️ IMPORTANT NOTICE ⚠️
These empty 18650 cells are non-functional and contain no active lithium-ion components. However, proper handling is still required to ensure safe and effective welding practice.
General Safety Guidelines
✔ Use only for spot welding practice—not suitable for real battery applications.
✔ Ensure proper ventilation while welding to avoid inhaling fumes from nickel strips.
✔ Always wear protective gear when practicing spot welding to prevent burns or injuries.
✔ Use a suitable spot welder with proper settings to avoid damage to the cell casings.
✔ Dispose of used practice cells properly after extensive use to prevent sharp metal edges.
✔ Store in a dry, cool environment to maintain the integrity of the metal casing.
🚫 Prohibited Uses & Handling
⛔ DO NOT attempt to charge these cells—they contain no lithium chemistry.
