Do you realize that the Lamp Battery lead was originally connected to a DC
supply? Connecting it to an AC supply doesn't validate your idea that they
ever called AC a battery.


I saw an old 1A2 PBX still using banks of batteries in the '70s at
the Pontiac dealership in Middletown Ohio. It had a couple racks full
of two cell, 4 volt clear lead acid batteries. Ohio Bell no longer
wanted to service it, so they replaced it with one of the early japanese
electronic key systems. It was a real piece of crap. I never had any
problems with the telephone to page interface in the Western Electric
1A2 system, but in a years time four separate paging interfaces
exploded. They had the design too close to the limits, and lost a lot
of aluminum electrolytics every time there was a power surge, or a
nearby lightning strike. BTW, Ohio Bell abandoned the old system in
place, so I took most of the 4 volt batteries and used them around my
shop, for years. I also pulled out over 1000 feet of 25 pair cable when
I replace the wiring for their paging system. It made great pull wire,
since they ran from the upstairs equipment room, down to every place
that I needed to pull a new single pair cable.
