Notes

The PP series are all layer cells, often 4  or 6 stack of exact type used in "Batrymax"/"Radio Batteries HT packs (typically 4 x stacks of 15 "biscuit" style cells). There never was a PP2.

Connection type: socket

Perhaps  5000mAH or more depending on  load

Equivalents:

  • GEC BB31
  • Vidor T6011
  • Others: DT11, TR11, VT11

This facilitated Push Pull Direct complementary output with the loudspeaker connected to the centre tap. Some makers preferred to use 2 x AD28 for higher capacity centre tapped 9V (e.g. Perdio). Recommended for applications up to 50mA @ 9V

The 4.5V sections each use 1/2 of a PP9 interior and can be used in parallel or series.
