Does this sound familiar? Once again, the batteries of a device are empty, they are exchanged for batteries from which you have some time before loading times ... and then stands still without electricity because ... The only way, however is always some batteries for trickle charging in the charger stuck to have. Or? Of this I had eventually had enough, so I was looking for batteries that do not even discharge possible. For this purpose they should have a reasonable performance, I wanted to put them in the external flash "Sealife Digital Pro Flash" for my underwater camera, and nothing is more annoying than an empty battery during the dive. I've found the Eneloop- batteries from Sanyo. I am completely satisfied. The batteries are well finished, the self-discharge is hardly noticeable and the performance is very good. Even with intensive use (eg in said flash with many trips) keep the batteries with long. Meanwhile, I have exchanged all batteries against Eneloop- batteries, I use them for keyboard and mouse, Wii remote controls, flashlights, etc. I can only say that I have really convinced these batteries!
