⚠ Important Safety Warnings

Improper handling or misuse of this lithium-ion battery can result in FIRE, EXPLOSION, or THERMAL RUNAWAY, causing personal injury, property damage, or death. Users must read and follow all safety guidelines before purchase and use. Click here to review the full safety guidelines.

  • Critical Warning: Never carry loose batteries in your pocket, purse, or bag. Loose batteries can come into contact with metal objects like keys or coins, causing a short circuit, which may result in severe burns, fire, or explosion. Always store or transport batteries in a protective case.
  • Intended Use: This battery is designed for integration into protected battery packs with a Battery Management System (BMS) or Protection Circuit Board (PCB). It is not intended for standalone use or for e-cigarettes, vaporizers, or similar devices.
  • Thermal Runaway: A chain reaction where heat from a failing battery causes further overheating, potentially leading to fire or explosion.
    • Causes: Overcharging, short circuits, physical damage, or exposure to high temperatures.
    • Prevention: Use a smart charger, avoid damage, and store batteries in a cool, dry place.
  • Storage & Transport: Always store batteries in protective cases to prevent accidental contact with metal objects. Never store loose batteries in pockets, purses, bags, or near conductive materials.
  • Inspection: Do not use if the PVC wrapper, terminal insulator, or casing is damaged, dented, leaking, or bulging. Continued use could result in failure, fire, or explosion.
  • Charging: Use a smart charger specifically designed for lithium-ion batteries and ensure the charger's voltage matches the battery's specifications. Never overcharge, over-discharge, or leave unattended while charging.
  • Prohibited Activities:
    • Do not expose the battery to extreme heat, fire, or liquids.
    • Do not short circuit, puncture, crush, or modify the battery.
    • Do not charge or discharge beyond the manufacturer’s voltage range.
    • Do not dispose of in regular trash—always recycle at approved facilities.
  • Emergency Response: If the battery overheats, emits smoke, or swells, move it to a non-flammable surface (e.g., sand or concrete) and stop use immediately. In case of fire, use a Class D fire extinguisher or sand. Do not use water.
