Maintenance Tips

1. Use a Compatible Charger

Only charge with a LiFePO4-compatible smart charger. Avoid traditional lead-acid chargers unless lithium mode is supported to prevent overcharging.

2. Avoid Deep Discharge

Do not regularly drain below 20% state of charge. Lithium batteries last longer when kept between 20%–90% capacity.

3. Secure Proper Installation

Ensure terminals are tightly secured and free of corrosion. Confirm correct BCI Group 49 fitment for your 2022 Audi TT 2.0L to avoid vibration damage.

4. Monitor Vehicle Electronics

Modern Audi vehicles have advanced electrical systems. If installing, perform proper battery registration (if required) to maintain optimal charging system performance.

5. Protect From Extreme Heat

While LiFePO4 handles temperature changes well, prolonged exposure above 140°F (60°C) can reduce lifespan. Park in shaded or covered areas when possible.
