Warning! For safe usage, please follow these instructions:
1. Do not immerse the battery in water. Keep it dry when not in use.
2. Do not strike, throw, or expose the battery near fire or extremely hot conditions.
3. Charge only with a specified charger according to charging requirements (CC/CV).
4. Do not reverse the positive (+) and negative (-) terminals.
5. Do not put the battery into a fire or apply direct heat.
6. Do not short-circuit the battery with wires or metal objects.
7. Do not ship or store the battery with metal objects (necklaces, hairpins, etc.).
8. Do not knock, throw, tread, or bend the battery.
9. Do not directly solder the battery terminals.
10. Do not pierce the battery casing with nails or sharp objects.
