I have a Sony D7 portable CD player that comes with
a rechargeable battery pack.When I first got the player
the batteries would run it for about 4 hours. Now its
down to a little over an hour.

I'm certainly guilty of abusing it. I have both overcharged
it and run it to empty several times, contrary to the
instructions. The only thing I haven't done is used it
to often. I probably have only used it on batteries 25
times.

The battery pack is unique to this player, and costs about
$60 from Sony to replace. Given that the state of the art
has advanced in CD players, and costs have come down on new
ones its probably not worth replacing the battery pack.

I'm wondering if there is some way to rejuvinate them.
I've heard that the batteries "learn" some bad habits
and can be retrained with the right charge.

Any advise?
