PROTIP: DO NOT BUY the Wein cell!!!
Nope. Not at all. Here's what you do:
Go to Walgreens and obtain pack of zinc-air hearing aid batteries. I forget which size number it is -- it's the larger size (approx 3/8" diameter x 3/16" thick).
Get some aluminum foil and ball it up to make the battery fit in the well without shorting.
Alternately, if you have bought the Wein cell, when it goes out, do not throw it away... peel off the plastic/rubber(?) ring that says WEIN CELL on it, and replace the remaining battery with a hearing aid battery. One of the standard sizes will match here perfectly!
Dirty little secret... the Wein cell is just a zinc-air.. 1.35VDC. The PX625 mercury was 1.30. The difference in exposure reading is too small to be meaningful.
