Samsung 50E 21700 5000mAh Battery - Protected Button Top

⚠ Important Safety Warnings

While this battery is equipped with built-in protection circuitry to help prevent overcharging, over-discharging, and short circuits, improper handling or misuse can still result in FIRE, EXPLOSION, or THERMAL RUNAWAY, causing personal injury or property damage. Users must read and follow all safety guidelines before purchase and use. Click here to review the full safety guidelines.

• Intended Use: This battery is designed for use in flashlights, headlamps, and similar devices that require a button top configuration. Ensure compatibility with your device before purchase or use.
• Protection Circuit Limitations: While the protection circuit provides additional safety, it cannot prevent damage caused by misuse, including exposure to liquids, extreme heat, or physical damage.
• Storage & Transport: Always store batteries in protective cases to prevent accidental contact with metal objects (e.g., keys, coins, tools) that can cause a short circuit. Do not store loose batteries in pockets, bags, or other uncontrolled environments.
• Inspection: Do not use if the battery is dented, leaking, bulging, or if the outer wrapper or button top is damaged.
• Charging: Use a smart charger specifically designed for button top protected batteries. Do not exceed the battery's voltage and current specifications. Never leave the battery unattended while charging.
• Prohibited Activities:
  • Do not expose the battery to water, fire, or high heat.
  • Do not modify, puncture, crush, or attempt to disassemble the battery.
  • Do not use the battery if it becomes unusually hot during use or charging.
• Emergency Response: If a cell shows signs of thermal runaway (e.g., smoke, swelling, hissing, or heat), stop use immediately and, if it can be done safely, move it to a non-flammable surface (e.g., concrete or sand) away from combustible materials. Lithium-ion cells burn as Class B fires — use an ABC / dry-chemical fire extinguisher, or douse with large amounts of water to cool the cell and prevent the fire from spreading. Do not rely on a small spray; thorough cooling is required, and cells can reignite from residual heat, so monitor the area afterward. (Class D extinguishers are intended for lithium-metal batteries, not lithium-ion.) For any fire beyond a single small cell, evacuate and call emergency services.
