The PP5 was the size of an AAA [U16] It was used as far as I can remember during the 1961/2 period only in very small pocket transistor radios. I have an AERO that uses one but unfortunately don't have a dud one. They had a VERY short life. 9v with connections at each end similar to PP3 as mentioned. They cost 2/6d in 1962.

The PP4 was the size of a C cell with larger PP9 connectors at each end. The very early versions were rectangular.John.
