The battery is the same as is used in the PowerBraille. I never used the powerbraille's battery so I kept it as a spare for the optacon 2 which worked quite well. Also, people are naming their optacon instructors. Mine was Fran Bauer; I have no idea what happened to her after I left computer school. With all the discussion about training at TSI, I wish I'd had time to go there, but summer break was only a week long and I couldn't miss more than a day or two a month of school since the training was hectic; also, there were a lot of companies visiting our class, looking for prospective employees, since the end of training was just a month or two away.
