Be aware that the electrical characteristics of NiCd (if that's what
you currently use) vs. disposable cells are such that they may not
actually be suitable for digital camera use.
I had a (now defunct) digital camera which used 2xAA nicd cells. The
camera would not work properly with dry cells. I think this may have
been due to the fact that alkaline dry cells are unable to supply the
high transient peak currents which NiCd cells can. I don't pretend to
be an expert on battery technology and no doubt someone else will be
along shortly who can elaborate further/rubbish my theory. I guess if
you know your current camera works with conventional dry cells ok,
you are unlikely to have a problem.
