2. Safety Information
Always prioritize safety when handling and installing batteries. Failure to follow these instructions may result in injury or damage to the battery or vehicle.
- Proper Charger: Only use a charger specifically designed for lithium (LiFePO4) batteries. Using an incompatible charger can damage the battery and pose a safety risk.
- Secure Connections: Ensure all battery connections are secure and tight. Loose connections can lead to poor performance, overheating, and potential damage.
- Correct Polarity: Connect the positive (+) terminal to the positive cable and the negative (-) terminal to the negative cable. Incorrect polarity can cause severe damage to the battery and vehicle electrical system.
- Upright Mounting: This battery must be mounted in an upright position. Do not install it on its side or upside down.
- Vehicle Compatibility: Before purchasing and installing, confirm that the battery model, size, terminal configuration, and cranking current are compatible with your specific vehicle. Refer to your vehicle's manual for battery requirements.
- Avoid Short Circuits: Prevent metal objects from touching both terminals simultaneously, which can cause a short circuit.
- Temperature Range: Operate the battery within its specified temperature range. Extreme temperatures can affect performance and lifespan.

7. Maintenance
One of the key advantages of the EBL LiFePO4 battery is its minimal maintenance requirements:
- Maintenance-Free Design: Unlike lead-acid batteries, this LiFePO4 battery requires no activation, no acid, no water, and no regular maintenance.
- Charging: Recharge the battery using a dedicated lithium (LiFePO4) battery charger. Avoid using chargers designed for lead-acid batteries, as this can damage the LiFePO4 cells.
- Storage: For long-term storage, ensure the battery is charged to at least 60% and stored in a cool, dry place. The low self-discharge rate of LiFePO4 batteries means they retain charge much longer than lead-acid types.
- Battery Management System (BMS): The integrated Dynamic BMS provides maximum safety protection and active cell balancing, ensuring long-lasting reliability without the need for manual resets.

8. Troubleshooting
If you encounter issues with your EBL LiFePO4 battery, consider the following:
- Startup Failure: If your vehicle does not start, first check that all battery connections are secure and tight. Loose connections are a common cause of starting problems.
- Low Power: Check the battery's charge indicator. If the charge is low (e.g., 30%), recharge the battery using a compatible lithium charger.
- Slow Cranking: Slow cranking can indicate a low charge or an issue with the battery's capacity. Ensure the battery is fully charged. If the problem persists after a full charge, contact customer support.
- Incompatible Charger: If you are using a non-lithium charger, switch to a dedicated LiFePO4 charger.
