Default Eveready W-353 Battery Any info or sources available?

I am repairing a Simpson model 1699 precision milliohm meter and found one
of these batteries in it. There was also a standard 9 Volt Battery which
leads me to believe the unit is 20-30 years old.
I've searched everywhere and can't find any info on this battery and was
hoping someone could advise what its characteristics were and why someone
would use this versus a standard D cell in this application.
Its about 1 1/4 X2 1/4 X 4 Inches and 1.5 V and bears no date code
This is a great meter and I'd like to find the right battery and not need
adapt a D Cell
Thanks in Advance
Bob

Bob,

I've got a "Eveready Battery Engineering Data, Vol. III, 1984" book,
and **THAT** shows the W353 as discontinued. There is not much about it
other than its is an ANSI/NEDA 11, IEC R25-2 or a military BA802/U. the
dimensions are listed as:

Height 104 to 105.6 mm
width 64.3 to 65.9 mm
depth 33.3-34.9 mm

It is shown as a carbon -zinc type, but no current (amperage) or life
specs are given.

Best of luck in your quest,
Tim Schwartz

This battery type is long discontinued. If this is the old 22.5 Volt
battery. You can make one.

Get 15 of the small Lithium type watch batteries. Find a piece of small
cardboard or plastic tubing of the right diameter to hold the batteries
in series. Make a pressure contact to fit anb be fasened at each end.

This should serve as your battery for the meter. I have done this for
older photographic equipment and older radios.

Err, are not the open cell voltages of the lithium around 3 volts?
That would make it 7 or 8 cells to get close to 22.5 volts.
Maybe a CR2025/35 or such

You might see if this would work:
2725 EB-505 22.5 Volt Carbon Zinc Battery (505/M504/V74PX/W10)

I also recall garage door opener batteries that are 12 volts, two
would give you 24 volts. There about the size of a AA only shorter.

We used to use a 22.5 volt cell in portable phantom power supplies
for microphones. They looked like a 9 volt on steroids. Cannot
remember the number though.

Its actually only a 1.5 Volt battery which is why its seems strange that
they would use such a large Battery If I can't find one I'll just try a D
Cell ( would probably try to get it into the original package so I wouldn't
need to mess with the mounting"

Little watch batteries are 1.55V

Just use the biggest cell that will fit and cobble something together to
make contact. If a D cell works use it.

I opened it up and found two cells about 1.5 X a D cell tied in parallel so
it must be ea high current application. Tomorrow I'll put a couple of D
Cells in parallel and mount them in the original battery box

Bob-

That sounds about the size of an "F" cell. I would expect a modern
Alkaline D cell would have as much capacity as a carbon-zinc F cell.
