⚠ Important Safety Warnings
- Inspect Before Use: Always check that the battery terminal insulator is intact and properly positioned. Do not use the battery if the insulator is damaged, missing, or improperly installed.
- Use Correct Insulators: Only use insulators specifically designed for the battery type (e.g., 18650, 21700). Using incorrect or poorly fitting insulators may leave the terminal exposed and increase the risk of short circuits.
- Proper Installation: Ensure the insulator is centered over the positive terminal and securely adhered to the battery. Misaligned or loose insulators can expose the terminal and compromise safety.
- Avoid Damage: Handle the insulator carefully during installation. Do not puncture, tear, or deform the insulator.
