⚠ 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 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 the battery overheats, emits smoke, or shows other signs of failure, stop using it immediately. Move the battery to a safe, non-flammable surface (e.g., sand or concrete) and follow emergency protocols.
