I think I am the one who inquired about the optacon II. I really appreciate the responses that I got off list. My first question is if the Optacon II can be used just on a c. I made a major move a few years ago from Chicago to Florida and some how the battery got lost. I have the charger and the Optacon, but no battery. I have not used this equipment for quite a few years and am considering working with it again. So, I am wondering if I should just order a battery or send everything to Richard to have everything checked out and get a battery.
