where to buy auto exposure camera battery

Post by **PITIRRE** » Tue Mar 14, 2006 1:45 pm

Hi:

Last year I ask information about where to buy the battery that you put in a small compartment for reading the exposure of your camera, I have a GAF ST 802 and 602 also a I have a NIZO S-48-2. Tha GAF's use 2.7 volt and the NIZO use PX25 and PX13, I know that there is a substitute for the 2.7 volt.

Where can I buy this batteries? Thanks

Wein Cell:

$4.60 US

I have used them in a Canon 814 AZ and gave perfect exposure.

Or, if you don't want to pay $7.00 shipping for 2 batteries, you can get them here. It will save you a couple of bucks.

Good equivalent for PX 13 2,7 V battery, that I used for my R8 Sankyo Auto 5x are two watch batteries (forgot the name) 1,35 V each. Try to find in any clock-shop.

What about this battery?:

They are 1.5v and it says PX625A on the battery.

OK in some cameras, but not so good in others - best to try. The original mercury PX625 batteries were 1.35v, and the meters on some cameras will be inaccurate with 1.5v batteries. However, some will be fine. I used to have a Chinon 872 Power Zoom that worked perfectly with 1.5v batts.

As Splee says, some camears are fine with the modern alkaline battery and others are not.

The old mercury batteries, not really that dangerous but banned on environmental grounds, held their 1.35V steadily until the battery was almost completely drained.

The modern 1.5V batteries drop off slowly from the moment you start using them.

So not only is the nominal voltage different, affecting some metering systems enough to ruin exposure...the actual voltage changes over time.

I've successfully used the new batteries in a Chinon Pacific 310 super 8 camera, Eumig std 8 camera and a Kiev medium format camera....but I do hear that there are cameras that really don't get on well with the new batteries.

Two other expensive options exist..Wien cells and an adaptor which allows a smaller battery with a voltage regulator set at 1.35V to be inserted in the original battery compartment.

Wien cells only work if the small hole on each battery is exposed to air - so you'll need a hole in the battery compartment cover, and they're no good if you have to stack one battery on top of another.

BULLSHIT.

Well, I don't know if I'd put it like that, but, from all the research I've done on this, I think scott is right on this one Splee.

I was worried about it too and called Micro-Tools (the guys who sell the Wein Cells) and was told confidently that there is no problem stacking these zinc-air batteries in cameras that need two.

Then again, I've yet to actually put them to the test--I have a couple of brand new ones here waiting to get tested in the Nizo 801m as soon as I get some time. I'll report for anyone that's interested.

Splee, if you have a different negative experience, do share your story.

I tried using them in my old Chinon camera, which had no air hole in the compartment cover, and required two to be stacked, and they failed to work. They were OK for a very, very short amount of time, and would then fail to work unless I exposed them to air again for about half an hour.

It may be a case of just having to try and see - clearly in my case there wasn't enough air to make them work.

And I'd appreciate not being sworn at.

Right on, good info. If the two stacked wein cells don't work in my Nizo I'm going to go for the other (unfortunately, very expensive) option of using the MR-9 adapters (Angus mentioned above). Info here:

http://www.kyphoto.com/classics/mercurybattery.html

These guys sell them, click on "mercury battery adapters":

http://www.criscam.com/

Also check this page out for info on how to make a DIY battery adapter:

The $29.95 for the adapter seems steep, but its a one time expense and then you just use silver 386 cells which only cost $1.80! And you can use them in all of your cameras that use mercury cells.

I repect your opinion to call bullshit on this. I would like to add that the battery manfacture disagrees with you. So, if some folks (maybe not you, but others) go to the manfacture for guidance, they are told the above. I guess it is sort of like changing the oil in your car according to the manufactures recommendations. Some do, and some don't.

While I respect the opinions of others, I don't think it is bullshit when folks follow what the manfacture recommends.

Sorry, I was in one of those moods, and I was a bit blunt.

My experience has been that they worked fine stacked and in a closed battery compartment.

YMMV.

I used the two 1.5 v batteries from Radioshack (http://www.radioshack.com/product/index ... age=family) and when I went outside on a sunny day, the automatic exposure meter on my Canon Zoom 518 was all the way in the red zone past 16. So i'm guessing these batteries do not work?

I was shooting with Kodak Plus-X.
