Q&A

Maintenance Tips

1. Charge Properly
Use a LiFePO₄-compatible smart charger. Avoid standard lead-acid chargers unless they have a lithium mode.

2. Prevent Deep Discharge
Keep the state of charge above 20%; ideal range 20–90% for longest life.

3. Correct Installation
Ensure a clean, tight connection and correct BCI Group 49 fitment. Secure battery to reduce vibration.

4. Battery Registration
Some Audi A4 models require battery registration after replacement to optimize charging system performance—follow service guidance if needed.

5. Limit Heat Exposure
Excessive engine bay heat shortens LiFePO₄ lifespan; park shaded/cool when possible.
