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 or box.
• 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 use in devices such as e-cigarettes or vaporizers.
• What is Thermal Runaway?
  • A dangerous chain reaction where heat generated by a failing battery causes it to overheat further, potentially leading to fire or explosion.
  • Causes: Overcharging, short circuits, physical damage, or exposure to high temperatures.
  • Prevention: Use a smart charger, avoid physical damage, and store batteries in a cool, dry place.
• Storage & Transport: Always store batteries in protective cases or boxes 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. These are signs of internal damage or instability, and continued use could result in failure, fire, or explosion.
• Charging: Use a smart charger designed specifically for lithium-ion batteries and ensure that the charger's voltage matches the battery's specifications. Never overcharge, over-discharge, or leave unattended while charging.
• Prohibited Activities: Do not short circuit, modify, puncture, crush, expose to liquids, or solder directly onto the battery (spot weld only).
• Emergency Response: If the battery shows signs of thermal runaway (e.g., smoke, swelling, or heat), immediately stop use and move it to a non-flammable surface (e.g., concrete or sand). For fires, use a Class D fire extinguisher or sand—never use water.
