Recently, my 04 GT's batter had died, unexplainably. We figured since it was a stock battery, it might be time for a new one. So we changed them out, and the next morning that one was dead. We took it to the shop, and the mechanic said it was a part that was leaking. He said if he took it out, nearly all of the electronics for the car would fail. He also said that the part was discontinued, and that we would have to go salvage one from another car. Does anyone know what this part could be, and if it is in fact discontinued? Thank you.
