Maintenance Tips

1. Use a LiFePO₄‑Compatible Smart Charger
Only charge with a smart charger that supports LiFePO₄ chemistry — prevents overcharging and maximizes cell life.

2. Avoid Deep Discharge
Keep battery above 20% state of charge; ideal range 20–90% for best cycle life and reliable starts.

3. Proper Fit & Secure Installation
Confirm correct BCI Group 49 fitment, clean terminals, and tight cable connections to reduce vibration wear.

4. Battery Registration/Coding (If Required)
Modern BMWs often need battery registration or coding after replacement to ensure the charging system operates correctly — follow dealership or service guidance.

5. Manage Heat Exposure
Prolonged high engine bay heat can shorten LiFePO₄ lifespan — park in shaded or cool areas when possible.

6. Routine Inspections
Every 3–6 months check:

• Voltage level

• Cable and terminal condition

• Signs of swelling or physical damage

7. Storage Best Practices
If the vehicle sits unused for extended periods:

• Disconnect the battery

• Maintain ~50% charge

• Store in a cool, dry place
