If they changed it, one could speculate they took a real bath on the warranty. I feel your pain. I go to the local Tractor Supply to get a 6 volt battery since nobody else carries them around here, and the max warranty they offer is two years. So because I dont drive my 6v trucks but a few times a year, I get about 6-8 trips around town out of them. And sure enough, almost to the month, the battery lasts two years! I could get an 8v Tractor Battery for 3 years! Im sorry to say, there probably is no solution to the warranty.
