Hmmm - I can't say anything specifically on the Vivitar unit, but
I normally use an "achiever" unit with ni-cads and have not had
any problems. However, I can also relate the following. Back in 
a previous life when working/teaching digital electronics design
we had a really neat unit to erase EPROMS. It was basically a flash
unit which emitted ultraviolet light. You put it on top of the eprom
and zapped it twice and voila! the 2716 (or whatever) was erased.
VERY fast. However, the downside was that if it took more than two
zaps, an internal temperature limiting circuit would kick in and
you'd have to wait ten minutes for the unit to cool down enough
to use again. In doing large amounts of erasing of stuff, I'd
go down to the physics lab and grab a bunch of ice. When the
thermal switch cut in on the eraser, I'd stick it inside a baggie
and drop it in the ice bucket, which would make it come back on
in a couple of minutes....

THANKS

(ps - still looking for batteries - incidentally, the everready
battery web site is cute (bunny!) if you have kids). Did you know
Everready is owned by Ralston-Purina (makers of bunny chow?).
