The battery on my '99 SVT--with only 23.5K miles on it--died yesterday. It looks like the battery literally sprung a leak, and the pint of caustic acid that oozed out actually dissolved one of the terminal leads.

I'm wondering how long the battery has lived on others' Contours. And what kills batteries faster, time or usage? My battery was 3 years old, but the mileage (usage) was awfully low.
