I found a late 1960s ITT SU-49/PAS-5 night vision goggles. Anyone know where I could locate a battery for it?
I read that the battery was a BA-1312/U, 3 volt battery FSN 6135-269-5843 and that the LR50 was a replacement, it’s not as it’s 1.5v .
Anyone have any info on this goggle and a replacement battery?
I’d love to see if they still work.

Well the LR50 battery did work, for a short while (around 5 mins or so). I did some cross referencing and the BA-1312/U battery supposedly is 1.3v not 3 volt and the LR50 is the closest you can get to it.
The goggles worked surprisingly well with a hand held IR light. They did became really dim pretty quickly, seemed like the battery didn’t last long at all. I haven’t checked the voltage yet. I’m going to clean all the contacts and see if that is my issue.
Super cool that these still work, really neat piece of history. Really narrow field of view and needs IR light to actually work but they do work.
