It went the way of television channel 1, more or less. :-)

I've got an old Simpson VOM which uses not only a (single) D cell
but an old and somewhat hard-to-find battery type - I don't know
the generic designation but I remember that an Eveready type 417
is the only battery I've ever found to replace it (though this may
say more about who my parts shops buy from than who still makes
these batteries).  It's something weird like 14 volts, though that
probably means 13.5 nominal.  Does anyone out there know the origin
of this battery, and if anyone else still makes replacements?

How about some good references on (modern) power cell technology?
I've seen some articles in e.g. Radio-Electronics, but they didn't
really get into anything much besides the PolaPulse...
