Finally! - The annoying battery changes in my two digicams is over! Both my Dimage Z5 as well with my Kodak DC8330 I had the problem again and again that was after a few photos the battery to its knees, or the device turns off again the next time due to low voltage immediately. And both batteries (AA) as well as in ordinary batteries. The new technology of Sanyo maintains the tension uniformly high and the batteries last as long as not thought possible. I have now shot more than 100 photos with my Z5 and the camera still shows no signs of a weak battery. Great!
