Query: Did not work, disappointed on Disney vacation.

I had bought this battery as a backup on and charged it up in the Sony charger (or so I thought). On our trip to Disney and it did not work when our other battery died and popped this in for backup and missed several good pictures/memories that we can't get back:( I would like to exchange as I would hope it is a faulty battery, but don't know how.
