Sounds like the battery is good for a little over 2 years. My current car is closing in on 18 years. That's the equivalent of 9 battery pack warranties."
I own a 1976 Chevy truck and a 1979 Buick station wagon.
Cost of parts, insurance, registration sure is lower than the "new" trick stuff. They can keep it. I like my vehicles.
The Buick hasn't blown a gasket or seals yet?
