Battery Details.
Some sources list the IEC 2LR50 as one of these two, slightly different batteries, others list it as the other:
One of them has flat pads at opposite ends for the connection (A132), the other uses small snaps, 1 at either end.
I think the confusion arises because they are both out of general production but are made by smaller companies using 2 × LR50 cells. Possibly one is the closest that that particular company gets to the other, Look at the details and decide which is the best fitment for your application. A 123 Lithium battery may be used in place of the A132, but check polarity and fit as the A132 has a NEGATIVE pip whereas the 123 has a POSITIVE pip.
See: Jim's Polaroid Camera Collection, How I made a No. 532 battery replacement for details on how to make a lithium version of the 532 with snaps from an old 532 and a CR-P2.
