This battery is taken out of the closet and used it, in theory they have after one year approximately 80% of load capacity. Practically I have tested the capacity after one month and after that they had in 1990 mAh (according to my handlers) so that you can really do something.
The batteries come charged and can be used directly from the packaging.
Another advantage is the behavior at current drain more likely to have a higher voltage than normal NiMh batteries, thus showing eg lightning or digicams more fully and can use the battery better.
By the way as a kind of 4-transport box is included in the package, which can be used entirely.
