If the 12 v battery goes flat, then that's catastrophic.

1. What is the point of this battery considering there's a much larger battery already in the car

2. How do I know if it's going flat (apart from looking on the Kia app)

3. Since the problem is indeed catastrophic - can't unlock, can't start, need the AA - why don't Kia make the issue obvious

4. WHY does the battery go flat - why isn't there an alternator to keep it topped up

5. When it's going flat, how do I recharge it.

PS, it's a lovely car

PPS the charging flap wouldn't open, but it was fixed under warranty
