4. Installation and Setup

Before installation, carefully compare the connector specifications and polarity of your device with the battery. The red wire is positive (+) and the black wire is negative (-). Ensure these match to prevent damage.

Connecting the Battery:

1. Identify the positive and negative terminals on your device and the battery.
2. Carefully align the battery's 2.0-2P JST connector with the corresponding port on your electronic product.
3. Gently push the connector until it is firmly seated. Do not force it.

Note on Mismatched Connectors or Polarity: If your product's original battery has no plug, a mismatched plug, or mismatched polarity, you have options:

• You can cut the existing plug and solder the wires directly, ensuring correct polarity (red to positive, black to negative).
• Alternatively, use a heat shrinkable insulating sleeve to securely connect wires of the same color, maintaining proper insulation and polarity.

5. Operation

Once installed, the battery will power your electronic device. For optimal performance and longevity:

• Charge the battery fully before its first use.
• Use a compatible charger that provides the correct voltage (4.2V for full charge) and current for lithium polymer batteries.
• Avoid completely discharging the battery, as this can reduce its lifespan.
• Do not expose the battery to extreme temperatures (hot or cold) during operation or storage.

6. Maintenance

Proper maintenance ensures the long life and safe operation of your battery:

• Store the battery in a cool, dry place when not in use, ideally at around 50% charge.
• Avoid storing the battery fully charged or fully discharged for extended periods.
• Regularly inspect the battery for any signs of damage, swelling, or leakage. Discontinue use immediately if any issues are observed.
• Clean the battery terminals with a dry cloth if necessary to ensure good electrical contact.

7. Troubleshooting

If you encounter issues with your battery, consider the following:

• Battery not charging: Ensure the charger is compatible and functioning correctly. Check for secure connections and correct polarity.
• Device not powering on: Verify the battery is fully charged and properly connected. Check if the device itself has other issues.
• Short battery life: Ensure the battery is fully charged. Avoid extreme temperatures during use. The battery's lifespan can decrease over time with repeated charge cycles.
• Overheating: Discontinue use immediately if the battery becomes excessively hot during charging or operation. This could indicate a fault.

If problems persist after checking these points, please contact customer support.
