First 3 of 5 these batteries could be loaded in half the usual time. Unloading they were in half the typical time. I use since long like AAA 1000mAh batteries (Energizer, Varta, Sony and Duracell), so I can very well compare the values. I have about 7 load / unload cycles where the battery, in the hope that it gets better. The times have improved, the full capacity was never reached. Here I stopped because enough consumes my time and power. The other 2 have indeed shown better times from the beginning, unfortunately, did not last as long as the batteries other brands. So about 60% of the promised capacity in my estimation, these batteries can offer. That makes about 500-600 mAh.
Why is it I do not know. Either they were faulty from the start, or may have been destroyed by a long shelf life and a deep self-discharge.
Another gripe I have to give it. Neither the battery nor on the packaging is when the batteries were made or until when they are allowed to be used. Can not know whether the batteries are fresh (2009) or were stored for several years already one. Is not good.
Compared with the other batteries I've tried to make these my worst experience. So it must not be. The article I can recommend to any case.
