I can wholeheartedly to the comment of Vorschreibers join me here !!! (Dreamer of 10 May 2010) The very same "symptoms" has my set of these batteries. Example: Use this battery for over one year usually in a Canon flash (580 EX II). When to charge the batteries and used IMMEDIATELY then I can so well 350-400 flash shots, many of them make in rapid succession. Thereafter, the power falls pretty rassch from - this is so fine. It invites, however, the batteries 2-3 days prior to the actual use to then these (all 4 pcs.) As good as empty - perhaps 15-20% power remaining. Even if I want to use battery on after charging with prescribed charging current (original Sony charger) morning about 8h abstecke and this only in the afternoon is almost half gone again. Also checked whether the things I've already somewhere have a "hole" and lose the juice. Could nothing be discovered.
Pay over the next time all change me on ENELOOP, use it made a total of 8 pieces - really are the best !!! Anyway SONY is in the range battery with me down through - never again. Maximum 2 stars .... and which are still partly paid.
Incidentally, while I have these few lines written for this review, the price of the batteries has ratcheted up ...... but maybe they have improved in these 2 minutes ......
