The battery is fine and not swollen. I have a 2nd Harmony One and I swapped batteries between them. Both the battery from the dead H1 and backup worked in the backup remote. Neither battery worked in the dead H1. I've had my H1 for at least five years so I doubt that Logitech would be willing to replace it at this late date. I have no desire to own a Touch.
