Hi Alex,
     I don't know of any resources for Hungarian Labor Battalions, but if you are simply trying to determine the current name of the Hungarian towns, there are several things you can try.  1) the JewishGen Gazetteer and or Communities database.  It lists current and previous names of most towns.  2) Hungarian wikipedia.  Enter the Hungarian name in the search field and you will find the town according to that name and it will give you the current name as well. 3) If the town is in German and you need the Hungarian name, this web site might help:  https://en.wikipedia.org/wiki/List_of_German_exonyms_for_places_in_Hungary
     Best,
