Had with my previous Batteries (Ansmann) the problem is that my unfortunately too rarely used digital camera (Canon PowerShot S2 IS) always was not used because the batteries when I needed them. The eneloop (battery) Batteries everything no problem. Have months ago (!) Used the first charged battery pack and the second not yet needed. Brilliant! Really no comparison to the "normal" batteries. All that plagues a similar problem, I can only recommend the eneloop batteries.
