Maintenance Tips

• Check voltage monthly: Use a quality voltmeter to monitor the battery’s state of charge.

• Clean terminals: Keep battery terminals and clamps clean; remove corrosion with a baking soda solution and soft brush.

• Secure mounting: Ensure the battery is firmly fastened to reduce vibration and extend service life.

• Use a LiFePO₄‑compatible charger only: Recharge with a charger designed for lithium iron phosphate chemistry — avoid standard lead‑acid chargers.

• Avoid deep discharge: Recharge promptly after use; don’t let voltage fall below recommended levels.

• Temperature protection: Keep the battery away from extreme heat or cold for optimal performance.

• Inspect regularly: Check for swelling, damage, or loose connections; address issues immediately.

• Balance charge if recommended: Perform balance charging per manufacturer guidance to maintain cell health.

• Proper storage: For long storage, maintain ~50–70% charge and disconnect to reduce parasitic drain.

• Follow manufacturer guidelines: Adhere to PowerTex care, safety, and warranty instructions.
