Thanks CGRetired. I already have one 6exap that isn't working so I don't think I will fool around with another one. Just use the charger that came with it. I put new sanyo 2500 batteries in my TX. I guess I don't have to worry about them retaining memory. I really wanted the accu-cycle for my RX batteries. I don't want to lose a plane because the RX battery has a bad or weak cell.
