5. Operating Instructions

Once the battery is correctly installed, your device should power on. If the device does not power on, refer to the Troubleshooting section.

5.1 Charging

To charge the battery:

1. Connect your device (with the battery installed) to a compatible charger.
2. Ensure the charger meets the voltage and current requirements for 3.7V Lithium Polymer batteries. The standard charging current is 44 mAh, with a maximum of 220 mAh.
3. Monitor the charging process. Avoid charging in direct sunlight or extremely hot environments. The optimal charging temperature range is 0 ℃ to 45 ℃.
4. Disconnect the charger once the battery is fully charged to prevent overcharging, although the battery includes overcharge protection.

6. Maintenance and Storage

Proper maintenance and storage will extend the life of your battery.

• Regular Use: For optimal performance, use and recharge the battery regularly.
• Storage: If storing the battery for an extended period, ensure it is charged to approximately 50% of its capacity. Store in a cool, dry place away from direct sunlight and extreme temperatures.
• Cleaning: Keep the battery and its connectors clean and free from dust or debris. Use a dry, soft cloth for cleaning.
• Avoid Impact: Protect the battery from physical shocks or drops.

7. Troubleshooting

If you encounter issues with your battery, refer to the following common problems and solutions:

• Battery Not Charging:
  • Check if the charger is properly connected and functioning.
  • Verify that the charging cable is not damaged.
  • Ensure the charging temperature is within the specified range (0 ℃ - 45 ℃).
• Device Not Powering On:
  • Confirm the battery is correctly installed and the connector is securely attached.
  • Double-check the polarity of the connection (red to positive, black to negative).
  • Ensure the battery has sufficient charge.
  • If the device still does not power on, the issue may lie with the device itself rather than the battery.
• Short Battery Life:
  • Ensure the battery is being fully charged.
  • Check for excessive power consumption by the device.
  • Battery cycle life is approximately 300 cycles to retain over 80% capacity. If the battery has exceeded this, its capacity may naturally decrease.
