Maintenance Tips

• Use a Lithium-Compatible Charger – Always charge with a LiFePO4-compatible charger to prevent overcharging or damage. Avoid standard lead-acid chargers unless they have a lithium mode.
• Monitor Voltage Levels – Maintain charge levels between 20% and 100%. Avoid full discharges below 10V, as this can shorten battery life.
• Protect from Extreme Temperatures – LiFePO4 batteries function best between -4°F and 140°F. For optimal charging, keep temperatures above 32°F.
• Secure Mounting – Ensure the battery is firmly secured in the vehicle to prevent vibration or movement, which can damage internal components.
• Check Terminal Connections – Regularly inspect and clean battery terminals to prevent corrosion. Apply dielectric grease for added protection.
• Store Properly if Not in Use – If storing for an extended period, keep the battery at 50-80% charge in a cool, dry place. Disconnect to prevent parasitic drain.
• Avoid Jump-Starting from Lead-Acid Batteries – Jump-starting with a traditional lead-acid battery can cause voltage spikes, which may damage the battery’s Battery Management System (BMS).
• Monitor the Battery Management System (BMS) – The built-in BMS protects against overcharging, deep discharges, and overheating. If the battery shuts down, allow it to reset before recharging.
• Prevent Deep Discharges – While LiFePO4 batteries handle deep cycles better than lead-acid, frequent full discharges can reduce longevity. Recharge before dropping below 20%.
• Follow Manufacturer Guidelines – Always adhere to PowerTex’s recommended maintenance and charging practices to maximize lifespan and performance.
