The NEX-5, the battery is functioning properly without any tinkering necessary. The same also applies to charging using the standard charger. That the replica battery would have a lower capacity than the original, I can not confirm; in the self-discharge, he seems to me to a tick better before than the original. One probably. but I have only one on Mondays battery as original ... :). Both batteries are at me for 250-300 photos exhausted if I do not leave for too long the clippers on, without making photos. Definitely my photo tours are now more relaxed, I have no fear of empty battery before me running the "ultimate design" on the way. The life of the original is now expected to be even longer, since I no longer have 20 Sony-part - have to charge 30% of existing remaining capacity again in order to go on the next day can. The unusual color of the battery has advantages: you can find it easily in dark places / in dark corners (the camera bag) and there are no mix-ups more possible in hectic battery replacement actions.
