It's not about the battery pack but more whether the charger will take multiple voltages. Most chargers will work anywhere in the world and are called multi-voltage chargers. To check have a look on the back of the charger and see if it says 'input 100-240v' If it does then it will work fine wherever you are in the world, just get the relevant adapter for the plug socket.
