ward Posted July 24, 2005 Share Posted July 24, 2005 I have been using my old Rollei 3003 and when the five NiCads went dead I found that I had lost the charger for them. I got some NMH batteries and a NMH charger but then noticed in big bold letters in the battery compartment: USE NICAD BATTERIES ONLY. This camera was produced before NMH batteries were available (late 1980s). Can anyone think of any reason NMH batteries wouldn't work perfectly well in any application where NiCads were previously required? Link to comment Share on other sites More sharing options...
jimstrutz Posted July 25, 2005 Share Posted July 25, 2005 NiMH & NiCad batteries are very similar in power output. It's generally accepted that anywhere NiCads were approved, NiMHs will be fine as well. Link to comment Share on other sites More sharing options...
alex_lofquist Posted July 25, 2005 Share Posted July 25, 2005 The NiMH are more environmentally frendly, where the NiCds have the very toxic Cadmium. Link to comment Share on other sites More sharing options...
mike_elek Posted July 25, 2005 Share Posted July 25, 2005 I recall reading that with this camera you aren't supposed to use alkalines or regular manganese cells, so possibly the NiCAD warning referred to using only rechargeables. In some instances (hand tools, for example), NiCADs often worked better becuase they can handle the heavier electrical current requirements under load than NiMH, but possibly that has changed now as well. For a motor driven camera, I would think that the NiMH cells would be an even better alternative than the NiCADs because of the higher MaH ratings. Both AA cells deliver roughly the same voltage (1.25V-1.3V) over the life of the charge. Link to comment Share on other sites More sharing options...
RaymondC Posted July 25, 2005 Share Posted July 25, 2005 get a new battery charger. really. its time to move on. Link to comment Share on other sites More sharing options...

john_newell2 Posted July 26, 2005 Share Posted July 26, 2005 As a guess, the warning is intended to prevent using higher-voltage alkaline cells (1.5v or more nominal) in a circuit intended for the 1.2v nominal NiCd cells. NiMH cells are the same nominal voltage as NiCd cells, so if that's the reason for the warning you should be fine. However, don't call me if you fry the camera... <|;^) Link to comment Share on other sites More sharing options...
mskovacs Posted July 28, 2005 Share Posted July 28, 2005 NiMH - have faster self discharge rate (bad), higher storage capacity (good), no cadmium (good), higher internal resistance (bad for high current loads) I think in this case, they are a wise choice. If the camera spends a lot of time unused, then you may find the batteries die faster due to self discharge. Link to comment Share on other sites More sharing options...
