I purchased this same exact battery with charger and back cover on ebay. It cost me $15.88, the Battery is a 3500 mah and it fits well with the cover. It DID come from Hong Kong, and it took FOREVER to ship it, but the shipping was free and I am currently able to get almost 2 full days of use from it now! Before I would get a dead battery by dinner time if I was gentle on my browsing the net! For the money, YOU CANNOT GET A BETTER BATTERY DEAL!!! PERIOD!! I even tried to contact the company in hopes of getting one for my wifes LG Optimus M, but they do not currently offer one. The said one was in the works though. So, like I was saying. For $16 you get a helluva battery that is 100% compatible!
