No these packs have at least 25 cycles on the them some even more. I have tried a charge rate of one and up to three. This charger worked fine before, I have had this one for a couple of months now. It just started to act up the last couple of charges. I tested to see if I had a dead cell in the first pack it happen to but it has done it to all of them and I have a total of four packs. Thanks.
