Sanyo SCP 550 battery?

[Thanh]

Hi there :)

Anyone knows a website where i can get battery for the terminal Sanyo SCP 550 CDMA 1x?

I am short before getting this phone, and i heared it's battery (600 mAh original) get's empty very quick, i look for a replacement with higher capacity. Googling the net did not find anything.

Thanks for your help!
