6. Maintenance and Storage

To ensure optimal performance and longevity of your battery:

• Store the battery in a cool, dry place away from direct sunlight and extreme temperatures.
• The recommended storage temperature range is -20°C to 60°C.
• Avoid storing the battery fully charged or fully discharged for extended periods. A storage charge of around 3.8V-3.9V per cell is ideal for long-term storage.
• Do not expose the battery to water or moisture.
• Keep the battery away from metallic objects to prevent short circuits.

7. Safety Information and Precautions

Lithium Polymer batteries are powerful and require careful handling. This battery includes an integrated protection circuit to enhance safety, offering:

• Overcharge Protection: Prevents the battery from being charged beyond its safe voltage limit.
• Overdischarge Protection: Prevents the battery from being discharged below its safe voltage limit.
• Temperature Protection: Monitors and regulates the battery's temperature during operation and charging.
• Short Circuit Protection: Automatically cuts off power in case of a short circuit.
• Overvoltage Protection: Safeguards against excessive voltage input.
• Overcurrent Protection: Prevents damage from excessive current draw.

General Safety Guidelines:

• Do not disassemble, puncture, or modify the battery.
• Do not expose the battery to fire or extreme heat.
• Do not use the battery if it shows signs of swelling, leakage, or damage.
• Keep out of reach of children.
• Dispose of batteries according to local regulations. Do not dispose of in household waste.

8. Troubleshooting

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

• Battery not charging: Ensure the charger is compatible and properly connected. Check the charging temperature is within 0°C–45°C.
• Battery not powering device: Verify the connector polarity is correct. Ensure the battery is sufficiently charged. Check if the device itself is functioning correctly.
• Short runtime: The battery may not be fully charged, or its capacity might have degraded over time. Ensure proper charging cycles.
• Battery swelling: Immediately discontinue use and safely dispose of the battery. Swelling indicates internal damage and a potential safety hazard.
