The dealer wants $351 for a new EU456 battery. They are a European sized odd ball so they think they have to charge a high price. I know there are several of these tractors out there have any of you found a more reasonably priced battery to fit or do you just pay the price at the dealer ? The dimensions are 19 1/4 long 8 1/4 tall and 6 5/8 wide and needs to be 960 CCA.
