Help INfo on W-353 BAttery

While servicing a Simpson 1699 precision millivolt meter I found an Eveready W-353 BAttery.Its a 1.5 volt Battery that's about 1 1/4 X 2 1/4X 4 inches I 've searched the web and cannot find any mention of it which has me curious as to why such a devise would be used versus a standard D cell in this unit . The other battery in the device is a standard 9 volt battery. Would appreciate any info on where to buy this device and any particular characteristics that would preclude simply using a D Cell Thanks in Advance Bob

Eveready

Google: "A" (filament) battery, 1.5 volts - Listed as Neda Number 11, Eveready W353

Use a D cell if it fits and works. There used to be more radio battery types and shapes than you can imagine - now there are 4 basic ones. It's a PITA but that's life.

I sometimes wondered if meter makers in the old days used unusual 1.5 volt cells to stop them being pinched for other uses. Because most old meters were large enough to take a standard cell. And although as you say there were many types, say 50 years ago, the most common were still AA and D, in the UK, at least.

I have an old but good Taylor analogue meter - still useful where you really don't want a high impedance device. The 15 volt battery is still available, but not the 1.5. Which was IIRC, an HP11. Looking through the cats, as you do, and checking dimensions, I discovered an ancient design of hand lamp or cycle lamp 4.5v battery (with brass contact 'leaves') which was the same height and thickness. So stripped one out and sure enough inside were three HP11 sized cells. ;-)

The batteries were readily available back then.

We had a couple more for flashlights (torches) in NZ not including the various packs, some with voltage taps. And then there were many types for transistor radios, tube radios, telephones and photographic gear amongst others. Almost all gone now. I have a neat RLC bridge which takes a weird Euro 3 volt cell. I am running it on 2 N cells and a bunch of coins (to make them fit).

Yep. Times gone by.
