3. Safety Guidelines

Lithium-ion batteries can be dangerous if not handled properly. Adhere to the following safety guidelines to prevent injury or damage:

• Do not disassemble, puncture, crush, or short-circuit the battery.
• Do not expose the battery to water or fire.
• Do not use if the battery wrapper is damaged or torn.
• Do not expose to extreme temperatures (above 60°C or below 0°C).
• Always use a charger specifically designed for Li-ion batteries.
• Do not overcharge or over-discharge the battery.
• Keep batteries away from children and pets.
• If the battery emits an odor, generates heat, becomes discolored or deformed, or appears abnormal in any way during use, charging, or storage, immediately remove it from the device or charger and discontinue use.

4. Charging Instructions

6. Storage and Maintenance

Proper storage and maintenance extend battery life:

• Store batteries in a cool, dry place, away from direct sunlight and heat sources.
• For long-term storage, charge batteries to approximately 3.7V - 3.8V (around 50% capacity).
• Avoid storing batteries fully charged or fully discharged for extended periods.
• Use protective cases to prevent accidental short-circuiting when carrying or storing loose batteries.
• Regularly inspect batteries for any signs of damage, swelling, or leakage.

7. Troubleshooting

If you encounter issues with your Vapcell 18350 batteries, consider the following:

• Battery not charging:
  • Ensure the charger is functioning correctly and compatible with Li-ion batteries.
  • Check for proper battery insertion and polarity.
  • Inspect the battery for physical damage or wrapper tears.
• Short runtime:
  • Verify the battery is fully charged before use.
  • Ensure the device is not drawing excessive current beyond the battery's 3A continuous discharge limit.
  • Battery capacity may degrade over time with repeated charge cycles.
• Battery getting hot during use/charging:
  • Immediately discontinue use or charging.
  • This could indicate a short circuit, internal damage, or over-discharge/overcharge.
  • Dispose of the battery safely if it exhibits excessive heat.

8. Disposal Information
