Is that for a medical device? Try http://www.bulbandbattery.com/index.html
they show Catalyst Research batteries in their online applications catalog
but not by model number, rather by the equipment in which it is used.

Hi,

I'm looking to replace a blown Li 2.8V 0.65AH NVR backup battery in a
piece
of kit.

The original battery is marked "Catalyst Research B-600", but I cannot
find
new ones anywhere.

Any ideas gratefully received. An alternative small battery would be
useable.

Thanks

Mike
