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: PP9 style snap.

About 5000mAH depending on load

• NEDA 1603
• Varta 439

Very common on Table Model transistor sets, but Asian makers preferred 4 x C or 4 x D cells. Some models (e.g. Hacker RP18) used 2 x PP9.

Still available even in some "High Street" retail shops, though a premium price (Eveready branded as Ever Ready UK are gone). Using 6 x Alkaline AA cells is 2500mAH to 3000mAH in a replica pack may soon be the only source.

Later versions swapped the Waxed (inside) cardboard case for a directly printed metal can. The last versions use a plastic case with a wrapped on paper label
