Looking for PX 14 battery

Post by **EtiN** » Sun Jul 18, 2004 2:45 pm

Hi there,
I purchased recently a REVUE S600 camera, but I need a PX 14 battery to run the exposure meter. I couldn't find such batteries in France & Switzerland (aren't produced anymore). If you have one or know where to order one please tell me !
See you

Check out Weincells, they should do the job for you. For a PX14 (2.7v) you need two on top of eachother since they're 1.35v batteries:

You can also get an Alkaline equivalent to the old mercury cell. The only drawback is that it's 3.0V vs. 2.7V. In many cases this will throw your exposure off, however if you have an adjustment for exposure compensation you can dial it back in.

This place has the battery:

It's on their site as "3.0v Alkaline replacement for 2.7 volt 2MR9, EPX14, V14PX (scope reticule illuminators, Celestron finder, Many Super 8 cameras)"

They ship world wide.

Here is a source for Wein Cells for a good price:

That's all I do is stack 2 Weincells together and they work like a charm.

I use 2 x 1.4v zinc air hearing aid batteries - they're usually sold in chemists and some hardware shops. I'm not sure where you are - and since loads of manufacturers make them including Duracell (http://professional.duracell.com/start. ... ts/675.pdf) and Energizer (http://www.energizer.com/ezchange/featu ... tional.htm)
you should find them easily.

In Sweden i paid about sek50 ~ $5 for 6.

They are narrower than the original batteries I need and sometimes mucg shallower, but I just use some washers or a nut and some electrical tape to make them up to the right size. They work like a treat.

Hi, i recently found someone on ebay which had a couple of these for sale for 99p.. let me see if I can find his username..

his name is vcl1964, but currently he doesn't have them for sale.. try sending a message or something..

I've never tried so don't quote me but I think you have to be a bit careful using the Alkaline batteries as the output voltage drops quite quickly as they are used. With a light meter this will mean that the readings will begin to deviate as the battery wears out.

The zinc air batteries manage to give a more opr less constant output througout their life.

I think if the meter does give the same (or close enough) results with 3 volts as opposed to 2.7 you should try and use silver oxide as the output voltage remains more constant during the life of the battery.

I got this information from http://www.rolleiclub.nl/batt-adapt-US.pdf where a guy has made extensive research into replacement for 1.35 volt mercury cells and has developed an adaptor. He tested all different kinds of button cells. For these adaptors to work properly you need to use silver oxide batteries.

The silver oxide 1.5v batts are dead cheap too. I think I got 5 for 99p and you can get them in loads of camera shops.

I would get some wiencells to start with. Then you will know you have a 'true' reading (if the light meter is still accurate!). Then you can test with 2 x 1.5 volt silver oxides and/or 1.4 hearing aid batteries and see what the difference in readings is - if there is any - then make your choice as to which is the best option.

good luck

Hi again !
thanks to you all for those replies, they'll be helpful ! I 'm a completly new super 8 user and this web-site is great ! Cheers...

I think you can also build one of those adapters very cheap, with a diode or something.. http://www.micro-tools.com sells diodes for this specific purpose! If anyone knows how we could easily drop 1.5v to 1.35v with a steady output.. don't hold back

This article is all about doing precisely that

http://www.rolleiclub.nl/batt-adapt-US.pdf

this guy has investigated in depth into doing this. He tested different battery options and which diodes will be best for different current drain of the light meter/camera in question. As well as selling adaptors and kits he's also given out all the data and observations he collected, so I would use this as a starting point.

good luck

hey that sounds awesome! Now I can go for the nizo's lol.. joking ;)

Thanks dude, really helpful document!
