For the BP-E1 (NOT the power booster) Canon service said there is a warning that when NiMHs are used it is possible that the camera sucks them too empty so that they get damaged before the camera turns itself off. So it is safer to change the NiMH AAs as soon as you notice they are becoming empty. I don't know how theoretical this is though, and where is the limit before harm starts to happen. >One thing that I found out though is, the flash doesn't seem to get fully >charged with my freshly recharged NiCds. Maybe it's the lower voltage? I have noticed the same with my cheap and small Cullman slave flash. It takes ages for the ready light get on even though the flash works before that. Used NiMHs.
