The Die Hard I bought in august of 2000 , died in october of 2006 it was a $110 battery 5 yr warranty (yaerly cost to me was $18/yr, I replaced it with a cheap Autozone ($45 )on our cruise to Shiner that day my Die Hard died,( we`ll see the yearly cost later)...Optimas are great ,had one red top in my Healey...not sure you get the 'extra' out of the extra price batteries though.....
