You haven't even told us whether they're NiCads or NiMHs. In any
case, perhaps you're coming at this from the wrong end. Anything
over 1.2volts might be reasonable, but that's an off-load voltage
you're measuring and what you should be interested in is an on-load
voltage.

And the batteries ability to retain its charge, something that does
deteriorate with the age (or amount of use) of the batteries.

Neither NiCads nor NiMH are all that suitable for cameras -- if you've
a camera that takes AA batteries, put in good-quality alkaline
batteries.

Your digicam is due for replacement, if it's done seven years.

That would depend on the OP's requirements. If the camera does what he
needs it to do and produces results that meet his requirements why
should he change it?

Make
sure your new one has a Lithium-ion battery built in and that it can
be charged in the camera. Far more suitable for camera use than NiMH
or NiCad.

I'd disagree there. I use rechargeable NiMH batteries, if they run flat
it's a matter of moments to pop in a set of ready charged ones (or the
reserve set of unused Duracells I keep in the camera bag). Far better
than waiting for the internal battery to recharge and if you're half way
up a deserted mountainside that isn't even an option.
