Looking back at my records I purchased the battery March 8, 1981 for $114.00 (which was a lot of money back then). 2 or 3 years after I purchased the battery JCPenney got out of the automotive business and contracted Firestone to handle the replacements.
The battery has been replaced 5 or 6 times under warranty (by Firestone) since the original purchase.
I think I've gotten my money's worth out of the lifetime warranty.
Anyone else have one of these batteries in their car?
