RE: Is my new charger working properly?
If they are within .5 volts of each other they will be fine. If you feel the charger is faulty contact the shop and aske for an RMA form and send it back for a replacement. I'm guessing that if your A123 cells are yeilding the same result that you may have a charger with an issue of some type. This is the first I have heard of anything like this with a hyperion charger.
