Maintenance Tips

• Use a Lithium-Compatible Charger – Always charge your LiFePO4 battery using a LiFePO4-specific charger to avoid overcharging and damage. Lead-acid chargers are not compatible and can reduce battery life.

• Maintain Charge Between 20% and 100% – To extend battery life, keep the charge level between 20% and 100%. Avoid letting the battery drop below 10V, as deep discharges can permanently damage the battery.

• Temperature Considerations – LiFePO4 batteries perform optimally in -4°F to 140°F. Ensure the battery temperature is above 32°F before charging to avoid cold-related issues.

• Proper Installation – Ensure the battery is securely installed to prevent vibrations that can damage internal components and cause long-term performance issues.

• Inspect and Clean Terminals Regularly – Periodically check for corrosion or loose connections at the battery terminals. Apply dielectric grease to prevent oxidation and maintain good contact for efficient power transfer.

• Storage Best Practices – If you plan to store the battery, keep it at 50-80% charge and place it in a cool, dry location. Disconnect the battery to avoid parasitic drain from your vehicle's electrical systems.

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

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

• Limit Deep Discharges – While LiFePO4 batteries handle deep discharges better than lead-acid, avoid discharging the battery below 20% on a regular basis to maintain its lifespan.

• Follow Manufacturer Guidelines – Always adhere to the manufacturer’s recommendations for charging, storage, and maintenance to ensure the LiFePO4 battery delivers optimal performance throughout its life.
