Hi Jim:

I have a SONY ICF SW7600GR and enjoy it. As with most portables, It's
best to use batteries. I use rechargables in mine and they work great
lasting around 30+ of play hours before recharging is necessary.

If you need to turn up the volume like I always did at work then expect
20-25 hours. You'll know when its time to change batteries as it'll
just shut off instead of getting quieter.

What Sony does is they drain the batteries down to something like 0.6V,
then cut off the radio operation so that the battery retains the
memory. This puts a strain on rechargable batteries that are not
supposed to be drained below 0.9V.

The Sony SW100, which is basically the same design miniaturised, and
has very similar if not identical performance, runs off 2AA batteries,
and therefore cuts them off at a higher voltage which is perfectly
kind to rechargeables.

Incidentally, with resepct to being a bedside radio, not only are the
SW100 buttons easy to distinguish and operate in the dark, but they've
thoughtfully put a little wart beside the headphone socket so that you
can easily find it by feel in the dark.
