I can agree with you in the warranty replacement hassle TIGGER. Just like my Die Hards though, they drain and charge the battery first and then test each cell before replacement.
I have had the Die Hard in my 78 Sedan (w/upgraded sound system) for four or five years now without any issues. Starts great in the cold, little to no corrosion on my terminals and even holds a strong charge after leaving the headlights on for an hour with the car off!
