    Do Wein cells (625 replacement) poop out fast??

    I want to use them in my Nikkormat FTn, Canon FTb, & Goessen Super Pilot cds.

    I have found the Kodak branded ones to last longer than the Wein. For all I know it could just be luck, but the Kodak ones tagt I have had in camera have lasted probably 9 months dor far

    I found with the Goodman adapter the 1.4 V batteries last longer and widely available. The .25 V increase of voltage is not that extreme and you can make adjustments. I use it in my Canonet QL 17 GIII

    Weincells were improved a few years ago and now are said to deliver up to a year.
    This is the most correct replacement for 625 mercury batteries. Any other solution is just that: an alternative way.
    As above, I favour ZA675 with an O ring to centre the battery. The ZA675 doesn't last more than a couple of months.

    Lots of people use the hearing aid cells and block some holes up.
    The zinc cells are higher voltage than 1.3 of mercury but drop to 1.3 under load in most applications, eg they should be ok in a canonet.
    Your other option is to use a silver cell and point contact diode.
    Some cameras can use the alkaline cells cause they use a bridge circuit or differential galvanometer.

    I got one bigger beef with wein cells than the short lifetime. The two times I've used one both of the time they ended up leaking green goo all over the place when depleted.

    Schottky diode, not point contact. Best is to select the type of Schottky diode according to data sheet so that the voltage drop is close to 0.2V for a current of 1mA.

    The one I put in my Nikkormat Ftn lasted 37 months with all but one of the airholes blocked off. Wein cells are a waste of money IMO.

    I find the Wein cells very uneven. Some last nearly a year, and I just had two that never worked at all. This was really frustrating, as the cells were in their plastic sleeve and the tape was well in place. I put two each in each of my FTN meters, and neither meter worked. I checked the voltage and one in each meter still read "0" after about an hour. The other two were fine.
    I have used the 675 hearing aid cells with the brass rings also with uneven results. Went to buy some at the drugstore the other day and the ones in the package were already corroded. Showed them to the clerk and he just shrugged his shoulders and went on about his business. I think these larger cells are not popular any more so they don't sell very quickly.
    Sure miss the old PX13's, they were always good. Damn government!

    Oops, Kodak just did!
    For all practical purposes, they've taken Kodak away.
