6. Maintenance

Proper maintenance ensures the longevity and performance of your Timeusb LiFePO4 battery:

• Storage: For long-term storage, charge the battery to 50% state of charge (SOC) and store it between 14°F to 122°F (-10°C to 50°C). Recharge every three months if not in use.
• Cleaning: Keep the battery terminals clean and free from corrosion. Use a dry cloth to wipe the battery case.
• Regular Checks: Periodically check cable connections for tightness and inspect the battery for any physical damage.

7. Troubleshooting

If you encounter issues with your Timeusb 12V 100Ah Pro LiFePO4 Battery, consider the following:

• Battery Not Charging: Ensure the charger is compatible with LiFePO4 batteries and properly connected. Check the charging voltage and current. The BMS may have activated a protection mode (e.g., over-discharge) if the battery voltage is too low.
• No Power Output: Verify all connections are secure. The BMS might have activated a protection (e.g., overcurrent, short circuit, high temperature). Disconnect the load, wait a few minutes, and reconnect.
• Reduced Performance: Check the battery's state of charge. Ensure the operating temperature is within the recommended range (Discharge: -4°F to 140°F / -20°C to 60°C).
