Polaroid's flat OEM battery, from the SX-70 filmpak

Mar 20, 2007 10 Replies

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 datasheet in their dusty cabinets?



Thanks, - Win

I think it was called the "PolaPulse". (?)

Wow, that's a fast respone! Yes, that's it, and instantly got me a datasheet for their P100,

I thought it was called PolaPulse.

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.

That PDF designates a PolaPulse(TM) that is different in configuration than the ones i mentioned (and have). Same technology and basic design.

Are these dims in inches? I thought they were about 1/4" thick; even the whole film pack wasn't an inch and 3/4; more like 0.7 for the whole film pack, IIRC.

How about posting a pic somewhere?

Thanks, Rich

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.

Actual measurements; yes, inches. From the 600 Plus film packs; obviously different than the PolaPack 100. Maybe i could Snail one to you.

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.

Oh, that won't be necessary. :-) Apparently I've only seen the model 100; and there's no reason to think you're making anything up. :-)

Thanks! Rich
