- 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.
