I think the issue is with German batteries not lasting long in warm and humid climates. Our family in Hawai`i was a BMW/Mercedes/Porsche one for many years and the OEM batteries always died early. 18 months sounds about right. IIRC we used to get about 3 years or so out of the Die Hards we used to replace them with.
