It can be as promised in the original charger that this goes just as fast (or slow) as the original battery.
The term "seems" to me to be slightly shorter than the original. The label on the battery shows the following performance data: 1000 mAh at 3.7 Wh (On the picture and in the description can be seen or is, quote: "for Fuji NP-50, 3.7V and 750mAH".).
I can not report long-term experience.
What bothers, and this may have already posted some reviewers, is the thickness of the battery.
He does not go well in the camera but out again. I have to pry out the battery with an object, which is annoying.
Having compared the battery times measured and the values to the original battery, it should be noted that the values are almost identical.
(For example: Original thickness above - contacts 6.50 mm - 6.44 mm Patona battery / original thickness below 6.42 mm - 6.36 mm Patona battery).
The Patona is even a little thinner.
The problem with removing remains. Why is it now mE?
The Patona battery is much less compact and also a little easier. Overall, a little unstable, you can move eg the pages easily. In my opinion, shed for something less.
Take out the problem with my copy bearing, the foil is umklebt the battery is.
The dissolves at the edges very slightly and overlaps partially a bit about, so that the film slightly tilted when removing.
Remedy to create a tool that allows you to battery heraushebelt some (annoying).
I've been using a sharp utility knife a little of the film (about 0.5 - 1 mm), at the end without contact, on the side facing the lens away. I also think the camera to remove the battery level.
So there are now nearly gone.
