I know there's a lot of photographers in this community, so I thought I'd post my tutorial here. I collect vintage Polaroid cameras, and unfortunately, the batteries are becoming harder to find and they're pricey. So I converted it from using the #532 battery to 2 AAA batteries. While this tutorial is aimed towards the 420, the following Polaroid Land Cameras also use the #532 batteries:
The 103, 104, 125, 135, 210, 215, 315, 320, 330, 430, 440, M60, and Countdown 70 all use one No. 532 (3 volt) alkaline battery.
For these, you may be able to use the tutorial as a guide.
