Storage & Usage: During long-term storage, keep the battery charged between 40% and 60%. We recommend charging the battery once every 3 months after receiving it, maintaining a voltage of 3.7-4.0V. Store the battery in a cool, dry place.
Over-Discharge Protection: When the battery is about to deplete, and the voltage drops to 3.0V, the protection circuit will shut down, preventing further discharge and providing over-discharge protection.
Over-Charge Protection: During battery charging, when the voltage reaches the maximum battery voltage (4.2V), the protection circuit will automatically cut off power, indicating that the battery is fully charged and providing over-charge protection.
Short Circuit Protection: In the event of a short circuit, the protection circuit will automatically shut down within milliseconds and will not power on again. Note that if the battery is short-circuited (bypassing the protection circuit), the protection circuit may also fail due to prolonged high current or component overheating.
