I'm trying to find some engineering info on Polaroid's flat battery,
you know, the battery they designed for the SX-70 camera filmpak,
and then sold as an inexpensive flat OEM battery. Didn't they call
it the PolaVolt? Maybe not, because there's nothing on the web by
that name (except for some cyclic voltammetry stuff). Does anyone
remember, or perhaps someone has a data*** in their dusty

cabinets?


Tradename *on* the battery packs from filmpacks for their OneStep Flash camera: "Polaroid PolaPulse(TM) Battery".
Size: 3.50 X 4.25 x 1.70 (appx); nominal voltage 6.0V (after all of these years, mine are around 5.8V).
As i remember it, they use the Leclanche design.
Approximate size of the active area is 2.0 X 1.5; if you want i

could

Snail one to you.



IME, they were unlabelled. The one in the camea packs were of a carbon-
zinc leclanche design. I have a pocket flashlight here someplace with one. I have used them to power a portable radio, and in fact Polaroid had a radio you could plug whole spent film packs into, to power the radio.
The ones i have (from Polaroid 600 Plus packs) are all labelled, i wrote what i read - if theer had been no labelling or designations, i would not have responded.
