Maintenance Tips

• Use a Lithium-Compatible Charger – Always charge with a LiFePO4-specific charger to prevent overcharging or damaging the battery. Avoid using lead-acid chargers as they can harm the battery and decrease its lifespan.

• Keep Charge Between 20%–100% – Maintain the battery charge between 20% and 100%. Avoid discharges below 10V to prevent permanent damage. Regularly check the charge level.

• Temperature Range – LiFePO4 batteries perform best in -4°F to 140°F. Ensure the battery is above 32°F when charging to avoid any temperature-related issues and maintain optimal performance.

• Proper Installation – Securely install the battery to minimize vibrations. Vibration can cause damage to internal components, which reduces its lifespan.

• Regular Terminal Inspections – Periodically check for corrosion or loose connections at the battery terminals. Use dielectric grease to prevent oxidation and maintain a solid connection.

• Proper Storage – If storing the battery for an extended period, keep it at 50-80% charge and store in a cool, dry place. Disconnect the battery to prevent parasitic drain when not in use.

• Avoid Jump-Starting with Lead-Acid Batteries – Do not use a lead-acid battery for jump-starting, as it may cause damaging voltage spikes that affect the Battery Management System (BMS). Always use proper jump-starting equipment for LiFePO4 batteries.

• Monitor 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 attempting to recharge.

• Prevent Deep Discharges – While LiFePO4 batteries can handle deeper discharges than lead-acid batteries, avoid discharges below 20% to ensure a longer lifespan.

• Follow Manufacturer Guidelines – Always follow the manufacturer's recommended care, charging, and maintenance guidelines to keep your LiFePO4 battery performing at its best.
