Maintenance Tips
-
Use a Lithium-Compatible Charger – Always use a LiFePO4-specific charger to prevent overcharging and damage. Avoid using standard lead-acid chargers, which can harm the battery’s internal components.
-
Maintain Proper Charge Levels – Keep the battery charge between 20% and 100%. Discharge below 10V can damage the battery and reduce its lifespan. Regularly monitor charge levels.
-
Monitor Temperature Range – LiFePO4 batteries operate best in -4°F to 140°F. Ensure the battery temperature is above 32°F when charging to prevent damage and maintain optimal performance.
-
Proper Installation – Ensure the battery is securely mounted to minimize vibrations, which can cause internal damage and decrease the lifespan of the battery.
-
Regularly Inspect and Clean Terminals – Inspect the terminals for corrosion or loose connections. Use dielectric grease to prevent oxidation and ensure secure, efficient contact.
-
Proper Storage Practices – If storing the battery for an extended period, keep it at 50-80% charge and store it in a cool, dry place. Disconnect the battery to prevent parasitic drain.
-
Avoid Jump-Starting with Lead-Acid Batteries – Do not jump-start using lead-acid batteries, as they can cause damaging voltage spikes to the Battery Management System (BMS). Always use the proper jump-starting equipment for LiFePO4.
-
Monitor the Battery Management System (BMS) – The BMS protects the battery from overcharging, deep discharges, and overheating. If the BMS initiates a shutdown, allow the system to reset before recharging.
-
Prevent Frequent Deep Discharges – While LiFePO4 batteries handle deeper discharges better than lead-acid, avoid draining the battery below 20% regularly to maximize its lifespan.
-
Follow Manufacturer Guidelines – Adhere to the maintenance and charging instructions provided by PowerTex to ensure the battery’s longevity and performance. Regular care will keep your battery operating at its best.
