Hi all,

The PP9 is a large (much bigger than a standard 9V, also known as a
PP3) that is still available. Ever Ready in the UK had a range of these
the PP stood for "Power Pack". You can look at it on Wikipedia:

I've seen pictures but never had a Type B (67.5 volt battery) in hand. I
just got one at an auction in a box of tubes I bought. It looks just
like a giant 9v battery. Same sort of clips on top, just a tad larger.

It's a RCA No. VS 218.

Of course it's dead, but I'm keeping it because it's kind of
historic....

I imagine it dates back to the 1930s or 40s. But there is no leakage and
it's package is clean.

I just calculated. It must contain 45 cells inside its cardboard
container.
