Maintenance Tips
-
Use a Lithium-Compatible Charger – Always use a LiFePO4-specific charger to ensure proper charging. Avoid standard lead-acid chargers as they can cause overcharging, potentially damaging the battery.
-
Keep Charge Levels Between 20% and 100% – For best performance, maintain the charge between 20% and 100%. Avoid discharges below 10V to prevent permanent damage and reduce the battery’s lifespan.
-
Monitor Temperature Range – LiFePO4 batteries work best within the -4°F to 140°F range. Always ensure the battery is above 32°F when charging to prevent issues caused by low temperatures.
-
Proper Installation – Ensure the battery is securely installed in your vehicle to minimize vibrations. Excessive vibrations can damage the battery’s internal components, decreasing its lifespan.
-
Inspect and Clean Terminals Regularly – Check the battery terminals for corrosion or loose connections. Apply dielectric grease to prevent oxidation and ensure efficient energy transfer.
-
Storage Tips – If storing the battery for an extended period, keep it at 50-80% charge in a cool, dry place. Disconnect the battery to prevent parasitic drain from the vehicle’s electrical system.
-
Avoid Jump-Starting with Lead-Acid Batteries – Never jump-start with a traditional lead-acid battery, as this can cause harmful voltage spikes to the Battery Management System (BMS). Use compatible jump-starting equipment for LiFePO4 batteries.
-
Battery Management System (BMS) Monitoring – The BMS regulates charging and protects the battery from overcharging, deep discharges, and overheating. If the BMS shuts down, allow the system to reset before attempting to recharge.
-
Avoid Frequent Deep Discharges – While LiFePO4 batteries handle deep discharges better than lead-acid, avoid draining the battery below 20% regularly to extend the battery’s lifespan.
-
Follow Manufacturer Guidelines – Always follow PowerTex’s maintenance instructions for charging, care, and use. This will ensure the maximum performance and longevity of your LiFePO4 battery.
