I have an old Triplett 631 VTVM/VOM (that I use with classic computer
stuff, of course) that uses a Burgess XX15 battery.  The XX15 is 22.5V
and is no longer made.

There is a "fix" for this situation posted on the Web that substitutes
several currently made 22.5V batteries.  But, I'd like to see if there
are any other ways of replacing the XX15s.

So, does anyone have an old spec sheet for the Burgess XX15?  I couldn't
find anything on the Web.

Thanks,
Dave

Hi Dave
 First thing to concider is that this was a carbon-zinc battery. They
expect a large voltage difference over the life of the cells. Stacking
two 9 volt alkaline batteries should be enough to make the unit operate
properly, giving 18 volts. If you find a problem here, you can always
cut open a 9 volt alkaline battery and remove enough cells to make
up the 4.5 volts. The alkaline units have separate cells that can be
individually removed. This is unlike the stacks that are used in
9 volt carbon-zinc batteries. Be careful to leave enough welled strip
to solder to so you don't over heat the cells.
