I believe the original IFI backup battery was 700 maHr but many teams purchased packs that had greater capacity. 1400 maHr seemed to be the norm.

The router unlikely had an electrical failure. Have you tried using the "return to factory default" procedure to load the original settings? Wall wart power supplies are rarely regulated, so electronics already have internal regulators. The WRT610N requires 1.5 amps at the power input.

Tom, I think your description is that you were using a battery from a cell phone to power the router. Or were you using a cell phone charger/ power supply to power the router. In any case, a failure to provide 1.5 amps at 12 volts nominal might have caused the router to corrupt it's firmware settings making it appear dead. The factory restore procedure or a reload of firmware may bring it back to life.
