Unfortunately, I realized that neither the Micro nor Mignon batteries hinenpassen in my spot lights. Apparently the batteries are slightly larger in diameter or transmits the film a bit more, I do not know exactly ...
One could indeed force hinenschieben but that would be a unique pleasure.
I do not know whether anyone else has the same problems. Now I have a whole mountain Eneloop batteries lying around here, but they are usable only for remote controls or the like. Too bad!
The product is great but it falls short in detail.
If it would not work in a lamp, it would still ok but if it does not work in four different models, which is very annoying.
Will revert to the old Eneloop.
Addendum of 03/30/2015:
Property me now again the white Eneloops purchased and am completely satisfied. Adjust properly in all my LED spotlights.
