If Every Ready didn't make zinc-chloride batteries until the launch of Silver Seal was was the difference between SPx and HPx batteries?
They also made a C11 "For Transistor Clocks" and a special HP7, the number of which I can't recall, for calculators. Presumably these were designed for long life at low drain.
