Please read this manual thoroughly before installation and operation to ensure optimal performance and safety.
2. Safety Information and Precautions
Lithium polymer batteries are powerful and require careful handling. Adhere to the following safety guidelines to prevent damage, injury, or fire:
- Certified Quality: Each KBT lithium battery undergoes rigorous safety examinations, including UN38.3 test standards (low-high temperature, impact, overcharging, external short circuit, vibration tests) to minimize risks during production, shipping, and use.
- Charging: Only use chargers specifically designed for lithium polymer batteries. Do not overcharge or discharge the battery beyond its specified voltage limits.
- Temperature: Do not expose batteries to extreme temperatures (above 60°C or below -20°C for discharge, above 45°C or below 0°C for charge). Avoid direct sunlight or heat sources.
- Physical Damage: Do not puncture, disassemble, short-circuit, or modify the battery. Avoid dropping or subjecting the battery to strong impacts.
- Storage: Store batteries in a cool, dry place away from flammable materials. If not used for extended periods, refer to the maintenance section for proper storage procedures.
- Disposal: Do not dispose of batteries in general waste or by incineration. Recycle them at designated battery recycling centers.
- Polarity: Always ensure correct polarity when connecting the battery to a device or charger. Incorrect connection can cause damage.

4. Setup and Installation
Follow these steps to properly install the KBT Li-Polymer Battery as a replacement:
- Prepare the Battery: If replacing an existing battery, carefully cut off the old connector from the KBT battery's wires, ensuring enough wire length remains for the new connection.
- Select Connector: Choose the appropriate PH2.54 or PH1.25/2.0 JST connector that matches your device's requirements. Cut off a suitable length of heat shrinkable tube.
- Connect Wires: Carefully strip a small portion of insulation from the ends of the battery wires and the chosen connector wires. Connect the wires, ensuring that the positive (red) wire from the battery connects to the positive wire of the connector, and the negative (black) wire from the battery connects to the negative wire of the connector. Twist or solder the connections securely.
- Insulate Connections: Slide the heat shrink tubing over the connected wires. Using a heat gun or a lighter (with caution, keeping flame away from the battery itself), gently heat the tubing until it shrinks tightly around the connections, providing insulation and strain relief.
- Install in Device: Once the connections are secure and insulated, carefully place the battery into your device, ensuring it fits without bending or forcing.

5. Operating Instructions
Once installed, the KBT Li-Polymer Battery operates like any standard rechargeable battery in compatible devices. Ensure your device's charging system is compatible with 3.7V lithium polymer batteries.
- Initial Charge: For optimal performance, it is recommended to fully charge the battery before its first use.
- Regular Use: Use the battery as needed for your electronic device. The battery's intelligent protection circuit manages charging and discharging within safe limits.
- Recharging: Recharge the battery when your device indicates low power. Avoid completely draining the battery repeatedly, as this can shorten its lifespan.
6. Maintenance
Proper maintenance extends the life of your KBT Li-Polymer Battery:
- Regular Charging: If the battery is not used often, it is crucial to run out its capacity and fully charge it once a month. This helps maintain battery health and prevents deep discharge.
- Storage: Store batteries in a cool, dry place, ideally at around 50% charge, if they will not be used for an extended period. Avoid storing in extreme temperatures.
- Cleaning: Keep the battery and its connectors clean and free from dust or debris. Use a dry, soft cloth for cleaning.
7. Troubleshooting
If you encounter issues with your KBT Li-Polymer Battery, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Incorrect charger, loose connection, damaged battery/charger, device issue. | Ensure charger is compatible and connected securely. Test with another compatible charger if possible. Check battery for visible damage. |
| Battery not holding charge | Battery degradation, improper charging habits, extreme temperatures. | Ensure monthly charging if stored. Avoid deep discharge. Operate within recommended temperature ranges. If battery is old, replacement may be necessary. |
| Device not powering on with new battery | Incorrect polarity, faulty connection, battery not charged, device issue. | Verify correct polarity during installation. Check all connections for security. Ensure battery is charged. Test the device with a known working battery if available. |
| Battery swelling or overheating | Overcharging, internal short, physical damage, manufacturing defect. | Immediately discontinue use. Safely remove the battery if possible and dispose of it properly at a recycling facility. Do not attempt to charge or use a swollen battery. Contact support. |
