it is difficult to differentiate this battery model the model of the original brand. is it the same manufacturer? There is even the protective cap identical to the original. I feel reliability: it will have any problem to use the original battery or this one. where there might be a difference is the capacity or life. for capacity, announced greater, I did not notice any glaring difference: - The capacity is all very sufficiently to several hundred photos, - Use more or less the video mode changes the situation completely => not really compare the actual capacity, - No self discharge between 2 Photo notable days to 1 month apart. and it is too early to talk about life.
