What is the amperage you need?

Battery supply packs can be made up. But, this is costly.

A 240VDC battery is going to be tough to come by unless you go with a
custom build, but 45VDC batteries are readily available. Try some of
the big internet battery sites or just try Google, you will get plenty
of hits with a simple search.

http://www.batteryout.com --> has several 45volt DC batteries
available

Vintage electro-shock pyschotherapy systems used high voltage
batteries as well as older military communications systems.

assuming its not a typo: you choices range from companies who make large
UPS units and battery backup systems used in telecommunications to do it
yourself project stringing off the shelf batteries together.

you must provide more details of what you need.

For the 240V supply you'll need a holder for about 160 LR44 watch batteries,
or 20 car batteries connected in series.
The solution depends upon the current you'll need for your application.

Some older photo strobeflash units used a 400 or 500 volt battery. Check with
some photo shops

I my opinion, a 240 volt battery is dangerous. Yes I know you can
connect some batteries in series
and get the 240n volts. But, my concern would be leaky or short circuit
even though it might
be a fairly hi resistance could carry quite a lot of current. This
current can generate lots of heat
and the charring of insulation can cause the current to increase etc.
etc. Things can go bad at a rapid
pace

I know of a couple of fires that had their start with a leaky 250 volt
battery set. The solution to
the fire problem was replacement with DC to DC supplies run off of 48
volt batteries.

That probably is not the solution you need, but I would be careful with
250 volt batteries. I would not
build and ship a 250 battery

I work on equipment that uses 240volt batteries in a UPS. These things are rated in AMP/seconds. Normally thaey will hold the load for about 20 seconds.This is long enough for generator to start and pick up the load.
