Sounds right. But I have no electronic education. Where can I check the discharge current, when I buy a battery? Jens

These guys need batteries which withstand high current drain easily. Of course the currents they draw are way more ethan a flash draws, but still, some flashes can easily do 2-4 amps peak. Cameras as well. Now think this - in the quest for highest capacity, many makers do NiMH with even 2500mAh. Sometimes, these batteries have high capacity, but only at very low current draw. That's because of the higher resistance because the way they packed the "capacity" in. So it definitely pays to choose the right battery. Many of the super-high-capacity NiMH batteries just don't show real world advance over quite smaller but lower resistance batteries. Good brands are both Sanyo and Panasonic, as they are the true makers (unlike several known brands which just repackage the batteries from original source). Both offer different kinds of batteries with some even for very high current drain applications. And both offer good technical information including recommended maximum discharge and charge current for the battery. so when looking for some, don't choose NiMH that have discharge current of only about 1 Amp. About 2 Amps would be better for the camera. Hope this helps, Frantisek
