Maintenance Tips
-
Use a Lithium-Compatible Charger – Always use a LiFePO4-specific charger to ensure safe and efficient charging. Lead-acid chargers can overcharge and damage the battery, reducing its lifespan.
-
Keep Charge Between 20% and 100% – To maximize battery life, maintain the charge between 20% and 100%. Avoid letting the battery drop below 10V, as this can lead to permanent damage.
-
Temperature Considerations – LiFePO4 batteries perform best in temperatures ranging from -4°F to 140°F. Ensure the battery is above 32°F before charging to prevent performance issues or damage due to extreme cold.
-
Proper Installation – Install the battery securely to prevent vibrations that can damage internal components. Vibrations can also lead to premature wear and reduced battery performance.
-
Inspect and Clean Terminals – Regularly check the battery terminals for corrosion or loose connections. Apply dielectric grease to prevent oxidation and maintain a solid electrical connection.
-
Store Properly – If storing the battery for a long period, keep it at 50-80% charge and store in a cool, dry location. Disconnect the battery to prevent parasitic drain from the vehicle’s electrical system.
-
Avoid Jump-Starting with Lead-Acid Batteries – Never jump-start using a lead-acid battery, as this can cause harmful voltage spikes that damage the Battery Management System (BMS). Always use proper jump-starting equipment for LiFePO4 batteries.
-
Monitor the Battery Management System (BMS) – The BMS protects the battery from overcharging, deep discharges, and overheating. If the BMS initiates a shutdown, allow it to reset before attempting to recharge the battery.
-
Avoid Frequent Deep Discharges – While LiFePO4 batteries handle deep discharges better than lead-acid batteries, try to avoid discharging the battery below 20% regularly to ensure longevity.
-
Follow Manufacturer Guidelines – Always adhere to PowerTex’s recommended charging, maintenance, and care instructions to ensure the battery operates at peak efficiency for years.
