Digicams are ware energy guzzler, is clear. I use a long with the typical AA Mignon batteries. The problem is that conventional batteries are fully charged, the camera goes on strike but. If it ever goes to, she turns later than after the first photo. The reason: conventional (super powerful) batteries with many mAh (~ 2700) does not provide "fast enough" the necessary "high power" (!!) need to digicams. As a result, the batteries can also only be fully charged. The power is not enough and the camera goes out abruptly. These Panasonic batteries that advertise grade with a small internal resistance (or they can deliver a high current, which is the same) my problem is finally solved !! The camera runs and runs! Spitzenmäßig!
