Looks like my battery is dead, its the oddessey that came with the Nizpro kit, which was fitted quite a few years ago. Not bad going from some of the reviews I have heard on this batteries. So the main question is, what should I replace it with. Would I have much hope fitting a Optima D34 in the nizpro battery cradle, or should I go with a Fullriver replacement which I have read about. Suggestions?
