Battery replacement price

iPhone Battery Replacement - Official Apple Support lists U.S. prices...tax excluded.

İf you ask for apple store all prices are written in the of your reagion, country. But if you are looking for authorized service u had better call before going.. they may not , probably not, same with apple store. And if u wanna replace your battery at apple store don't forget to make reservation beforehand. By the way in my country we have only carry in service option unfortunately, it also depends on your reagion..
