Default Re: Anyone know the date range for these old batteries.

I think they were already available in 1967, certainly by 1968. When I was a student I bought a set of 6 for my Philips EL3585 tape recorder, but they were too powerful for its centrifugal speed regulator to cope with, the motor running too fast with fresh batteries, so I stuck with the ordinary U2 cells.
