watchout buying batteries that look orriginal from ebay. first of all they have printed 950 mAh under the sticker and second they die as soon as they hit 40% me and some friends all experienced this problem.

i really recommend buying orriginal batteries in orriginal nokia packages. because even the holographic sticker on the fake nokia batteries are almost identical to the ones nokia uses. you can only see the difference when you compare it with an orriginal one.

95% of the batteries that are sold for about 10~20 dollar are fake. even if the seller garantees its not.
