RE: Thinking about an HP-41CL
Choosing rechargeable cells definitely makes sense if the 41c is to be used on a regular basis. I used a DIY device similar to the one shown by Sylvain, albeit not as nicely elaborated. This works, although the adapters which Dave has found seem to be a more robust solution. In the past there was a real market of third party HP-41c accesories, also N size chargers. Alas, these devices made by the german supplier W&W are absolutely rare these days. I were lucky to get one from a friend in exchange for a well used 32sII. A very nice and reliable device which saved me money for many years. Regarding its simple construction (standard cell holders on top of a standard electronics casing) it should even be possible to tinker a comparable charger from a AA size model using appropriate N size battery holders. Of course, that would cost more than four ot those adapters shown above.
