Maintenance Tips

1. Charge With a LiFePO₄‑Compatible Smart Charger
Use only chargers designed for LiFePO₄ chemistry — prevents overcharging and tuning issues.

2. Avoid Deep Discharge
Keep state of charge above 20% — ideal operation is 20–90% for optimal cycle life.

3. Proper Fit & Secure Mounting
Ensure correct BCI Group 49 fit, clean terminals, and tight cable connections. Proper mounting reduces vibration‑related wear.

4. Register Battery if Required
Modern Audis like the RS4 may need battery registration after replacement to maintain proper charging system behavior — follow dealer/mechanic instructions.

5. Protect From Extreme Heat
High engine bay temperatures can hasten degradation — park in shade or ventilated areas when possible.
