I've just ordered "3x 1800mAh Battery + US Charger Sprint Samsung Galaxy S II Epic 4G Touch D710".
From what I've read, they should fit into out SGS. I am a little concered about the batter height, but I'll make them fit if they wont.
I will test each one of them after I receive them, I would like to know, did anyone else bought theese batteries and what is his/hers impression? Even if they are less then 1.8Ah (lets say 1.5Ah), they still are dirty cheap and better then a year old battery. I barely get 10hours of my battery and have to take my netbook with me all the time, 1.1kg is heavier then 3 extra batteries .
