2. Safety Information

Please read and understand all safety warnings before using the batteries to prevent injury or damage.

  • Do not disassemble, crush, or puncture the battery. This can lead to internal short circuits, overheating, or fire.
  • Do not expose to extreme temperatures. Avoid direct sunlight, heat sources, or temperatures below -40°C or above 70°C.
  • Use only compatible charging cables and power sources. Ensure the voltage and current match the battery's requirements.
  • Keep out of reach of children and pets. Ingestion can be dangerous.
  • Dispose of batteries properly. Do not dispose of in household waste. Follow local regulations for lithium-ion battery recycling.
  • Avoid short-circuiting the battery terminals. This can cause severe damage to the battery and potential fire hazard.
  • Do not mix with non-rechargeable batteries or batteries of different types/brands.
