The 7600GR, if you just leave it around for a month or so running its
clock, will badly wobble the weakest cell, which will be reverse-charged
by the stronger cells, if you use rechargeables (which everybody does).
Replace the batteries very regularly even if you don't play it.
I can generally revive the weakest cell using an old charger to
start it off, and then cycling it in a modern charger a few times,
but it would be better not to let the other cells get to it at all.
It's not a matter of running the voltage down to .6V, but that by
that time, the weakest cell is already charged backwards by the others.

On the internet, nobody knows you're a jerk.
Actually, both issues are something to worry about. The radio is
designed for alkaline cells AND to use them to retain memory settings.
This scheme works fine, but will overdischarge secondary cells.
