Heat in Boot — 5 Series Concern
The 5 Series battery sits in a boot compartment that can get extremely hot in Malaysia — particularly for cars parked outdoors. AGM batteries degrade faster at sustained high temperatures. If your 5 Series is parked outdoors daily, expect battery life of 3–4 years rather than the typical 5 years. Consider a battery blanket insulator and check battery health via ISTA annually.
