Maintenance Tips
-
Charge with a Lithium-Compatible Charger – Always use a LiFePO4-specific charger to avoid overcharging or damage. Ensure the charger is suitable for lithium batteries to protect the battery’s longevity.
-
Monitor Voltage Regularly – Maintain the charge between 20% and 100%. Avoid discharging the battery below 10V, as it may reduce its lifespan and performance.
-
Avoid Extreme Temperature Exposure – LiFePO4 batteries work best within -4°F to 140°F. For optimal charging, ensure the battery temperature is above 32°F to prevent damage.
-
Secure the Battery Properly – Ensure the battery is firmly mounted to prevent any movement or vibration that could damage internal components over time.
-
Inspect Terminals and Clean Regularly – Check the battery terminals for corrosion or loose connections. Clean them and apply dielectric grease to prevent oxidation and ensure proper contact.
-
Storage Guidelines – If the battery is stored for long periods, keep it at a 50-80% charge, and store it in a cool, dry place. Disconnect to prevent parasitic drain.
-
Avoid Jump-Starting with Lead-Acid Batteries – Jump-starting with traditional lead-acid batteries can cause voltage spikes, which may harm the Battery Management System (BMS) of your lithium battery.
-
Monitor the Battery Management System (BMS) – The BMS is designed to protect the battery from overcharging, over-discharging, and overheating. If the BMS triggers a shutdown, allow it to reset before recharging.
-
Prevent Deep Discharges – LiFePO4 batteries handle deep cycles better than lead-acid but should not be regularly discharged below 20%. Keeping the battery within this range ensures longer life.
-
Follow Manufacturer Guidelines – Always follow the manufacturer's instructions for charging, maintenance, and battery care to maximize the performance and lifespan of your PowerTex LiFePO4 battery.
