the optima warranty is BS .. I have 4 of them sitting in the garage, all still under warranty and all no one will replace. Why because 1. I cant find the reciept for 2 of them, and the other 2 were purchased down south and not here.
I went round and round with locals to the point they finally said no, dont bring them back. I called optima they said oh they will replace them anywhere if they are under warranty. I told them they wouldnt, and they said well they were sorry try another dealer. But the battery guy you are dealing with is FULL of it, 3 year warranty is 3 years. call optima tell him what he said maybe you can get somewhere.
If not, go to napa by a Napa Orbital, 10x's the battery a optima is
