Hey guys i just got this "ORIGINAL" battery off ebay but i feel like i got scammed.

http://cgi.ebay.ca/New-Original-Batt...#ht_2311wt_911

Battery graph says the battery is always at 100% and about 600mAh charge which is ******ed because my original battery actually changes power levels and goes up to 1250mAh.

What can I do? It looks a bit different than the original but quite close. And when I peel back the sticker it doesnt says nothing on it unlike the original which says samsung...

Help?
