Correct Ralph, went to the battery place, used some digital multimeter and said it was gone. It good once the alternator is doing its thing, but he said after a period of time it will struggle, which it does when starting in the morning.. Went to an autoelec, he connected it to some contraption which did its thing and came back with a 'replace' light showing.. I assume everywhere I go to is going to tell me to get a new one.. Think I'm just going to get a new one, probably a Fullriver (if they fit into the Nizpro battery tray, arronm uses them and I think he runs nizpro gear) and get a maintenance charger. I looked at the process on the Odyssey links from above, and I don't have the time etc, as its my daily. Once the new battery goes in ill look into it maybe.
