For some reason I'd always thought that the PP3 9-volt battery was
called a PP9 (9 for 9 volts) rather than PP3. I also remember a 4.5V
rectangular battery with screw terminals - the screw part was a
stepped conical shape, IIRC; that's not listed on the Wikipedia page.
If that is the one I remember, my grandparents doorbell ran off one of
those and the battery sat on the wood of the doorframe.
I had a transistor radio that used TWO of them!

Note that's two PP9s, not bell batteries.
Yes, I should have trimmed more of the quoted paragraph. Still bloody big
and heavy for a radio - as I found. But they did last ages. I had that
radio for years and years.
