How much voltage do Eneloops loose after a week? This is my situation in
more detail.....

I have an old Sony digital shortwave radio from the 1980s which works
slightly better on alkalines but I use Eneloops because it's cheaper.

Eneloops last about 9 or 10 days before the radio won't switch on.

I alternate between 2 sets of Eneloops. Each week I take the used Eneloops
out of the radio and put in a new set which were charged the week before.

How much voltage will the week-old Eneloops have lost? I am more concerned
about losing radio perfomance (which is why I am asking about voltage) than
total charge.

The answers to most of your Eneloop questions can be found he

If the radio has enough voltage to turn on and operate, you will not be
losing any perceptible performance.
