Re: Where are the missing PP* battery numbers?
At the risk of being a bit vague, I remember a battery from my childhood years that was about the size of two C cells stacked together and had a PP-style connector on each end. If memory serves, one powered the smoke alarm my parents had back then, and I may have encountered a European-made portable transistor radio which was powered by a battery like that. Dad told me they stopped making them because they were a mercury cell.
Sound familiar to anyone?
