Is this available for international use in 220V?
Yes, it is available but it is special order only.

Can these units be used as a trickle charger and be left attached to keep a charge on the battery while away from the aircraft extended periods of time? I sometimes do not fly for a month and would like to be able to leave this charging. Also, is this unit able to provide enough power to use for starting in the event of a dead battery?
Per the supplier: The output is regulated at about 14 or 28 volts, and the battery should be able to handle that for extended periods of time. The unit does not crank assist, and should not be left connected when starting the aircraft.

Can this unit be used to charge an aircraft battery cart? My company has several 28 Volt ground power units, composed of 2-12 volt and 1-4 volt batterys, and we are looking for a unit that we can use to keep the carts charged.
The manufacturer would recommend the APU BATTERY CHARGER SINGLE PIN PLUG 28V 25AMP. If you need a higher amperage, you can also special order a 50 AMP version.
