  • 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.
