Just an FYI - Since I do a lot of restoration work and have about 17 bikes in my stable I frequently am dealing with batteries. Many old batteries and maintain many batteries. I have used alsmost every battery charger out there and have come to recommend one type over all others. I have used the new hi-tech chargers like the Optimates and Odyssey chargers and found thay do not work well on old really dead batteries or batteries that have some sulfate buildup. Sometimes the newer charger like these will not even begin charging a really dead battery as the battery requires some voltage to be present for the battery charger to operate. About a year ago I bought a Schumacher SC300 Speedcharger (3amp). This charge uses a pulse like profile for charging batteries that works remarkably well. I have charged old dead sulfated batteries that have been sitting around for years and actually have brought them back to useable condition using this charger. The Optimate and Odyssey chargers would not work on these old dead batteries. Just wanted to share my experience with this charger for those who might be in the market for a new charger.
