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.

I had the somewhat unscientific but nevertheless distinct impression
that reception on my radio (Radio 4 FM and Radio 5 MW) got worse as the
battery ran down.
