Battery Charger %233053564 and Australia



Is this a global charger, I see it has many power point adapters. I would like to know if the kit includes an adapter for Australia which is where I am. Does it involve plugging the correct adapter in and selecting the local voltage ? I am trying to determine if the unit can be purchased overseas or if I must purchase locally to get the correct plug and transformer.
Also the 9.6V grips, do they have their own cells built in do you have to add your own nimh or nicad aaa'a ? Thanks.
