Yashica battery question

[optikhit]

Sorry if this question has been asked before. My Yashica GSN is now on the way. I just buy a PX28A battery for the camera. I wonder to know can the PX28A be directly used in the camera? Because it is 6V not 5.6V. And furthermore, are there any other alternative ways for GSN's battery? Thanks a lot.

I'm pretty sure the 6v PX28A works perfectly in the GSN. A stack of 4 button cells would work too. You just need to keep then touching the contacts--some use a small spring and wrap the batteries to keep them still.

The two most common ways are either to use the PX28A with padding and spring (as detailed on Matt's Cameras) or to buy an adaptor (available from the Yashica Guy).

For some time I´ve been using a plastic tubing of a suitable diameter (printing calculator roll core) to hold a PX28 battery inside, plus a short spring with a copper contact for the battery + terminal.
Unfortunately PX28 alkaline batteries don´t last more than 2/3 months (I think they should last at least twice) but they are cheap enough to carry allways a couple of spares in my bag.
I didn´t find yet another suitable battery for the GSN, but to be honest, I didn´t check all the batteries available at this moment. Four 1.5V silver oxide cells will also be OK, as derevaun said. Perhaps silver oxide cells would last longer than a PX28, but I didn´t make any test. in this case, the batteries should be insulated from the camera´s battery compartment.
Good luck.
Ernesto.

Thank you guys, suggestions are helpful. I now know how to do it, but I still worry about the different voltage. Then we can have many choices, for instance, 4*LR44cell, 4*625cell, PX28A, and etc. Am I right?

Thanks again.

Supposedly the GSN's have an internal regulator that ensures that the correct voltage is sent to the meter. I think this was because the old mercury batteries tended to fluctuate in voltage... I wish I could remember where I read it. Yashica Guy's website, maybe. Anyhow, hope that helps.
