Maintenance Tips

• Use a Lithium-Compatible Charger – Always charge the battery with a LiFePO4-specific charger. Avoid standard lead-acid chargers, as they can overcharge the battery and reduce its lifespan.

• Maintain Proper Charge Levels – Keep the battery charge between 20% and 100%. Avoid discharging it below 10V, as this can damage the battery and shorten its lifespan.

• Store in Appropriate Temperatures – LiFePO4 batteries work best in temperatures between -4°F and 140°F. For charging, ensure the battery temperature stays above 32°F to maintain performance.

• Secure Installation – Ensure the battery is mounted securely to prevent vibrations, which can cause internal damage and negatively impact its longevity.

• Inspect and Clean Terminals Regularly – Periodically check the battery terminals for corrosion or loose connections. Apply dielectric grease to prevent oxidation and maintain a strong electrical connection.

• Proper Storage Practices – If storing the battery for long periods, maintain a 50-80% charge and store it in a cool, dry location. Disconnect it to prevent parasitic drain.

• Avoid Jump-Starting with Lead-Acid Batteries – Jump-starting with a lead-acid battery can cause dangerous voltage spikes that may damage the Battery Management System (BMS). Always use the proper jump-starting procedure.

• Monitor Battery Management System (BMS) – The BMS is designed to protect the battery from overcharging, deep discharges, and overheating. If the system shuts down, allow it to reset before recharging.

• Avoid Deep Discharges – LiFePO4 batteries handle deep cycles better than lead-acid batteries, but frequent discharges below 20% can reduce their lifespan. Keep the battery charge within the optimal range for best performance.

• Follow Manufacturer Guidelines – Always follow PowerTex’s recommended maintenance, charging, and care instructions to ensure the best performance and longevity for your battery.
