Maintenance Tips

• Use a Lithium-Compatible Charger – Always charge your LiFePO4 battery with a LiFePO4-specific charger. Traditional lead-acid chargers may overcharge and damage the battery, reducing its lifespan.

• Maintain Charge Between 20% and 100% – Keep the battery charge level between 20% and 100% for optimal performance. Avoid discharging the battery below 10V, as deep discharges can cause permanent damage.

• Temperature Considerations – LiFePO4 batteries perform best within a temperature range of -4°F to 140°F. Avoid charging the battery in temperatures below 32°F to prevent potential performance issues due to cold conditions.

• Proper Installation – Ensure the battery is securely installed to prevent vibrations. Vibrations can damage the internal components, leading to reduced efficiency and performance over time.

• Inspect and Clean Terminals Regularly – Periodically inspect the battery terminals for corrosion or loose connections. Apply dielectric grease to the terminals to prevent oxidation and ensure a reliable connection.

• Storage Best Practices – If storing the battery for an extended period, keep it at 50-80% charge and store it in a cool, dry environment. Disconnect the battery from the vehicle to prevent parasitic drain.

• Avoid Jump-Starting with Lead-Acid Batteries – Never jump-start using a lead-acid battery, as this can cause harmful voltage spikes that may damage the Battery Management System (BMS). Always use equipment designed for LiFePO4 batteries.

• Monitor the Battery Management System (BMS) – The BMS protects the battery from overcharging, overheating, and deep discharges. If the system initiates a shutdown, allow it to reset before attempting to recharge.

• Limit Deep Discharges – LiFePO4 batteries are more resilient to deep discharges than lead-acid batteries, but avoid discharging the battery below 20% regularly to maintain its health and longevity.

• Follow Manufacturer Guidelines – Always follow the manufacturer’s maintenance and care instructions to ensure your LiFePO4 battery delivers optimal performance and lasts longer.
