alkaline vs silver oxide 6v battery replacement

[Noll]

Up till now, I have been using 6v silver oxide batteries in my yashica rf's along with the yashica guy adapters. The problem is that after about 6 months, the batteries are drianed, on or off, used or not and these little things are not cheap! I see that the alkaline versions are about half the price and although I am aware of the voltage drop associated with alkalines, if I can get the same 6 months out of them then it would be worth switching.

Anyone else using alkaline and if so how long are they lasting you in the yashica rf's?

I only used alkalies when I had a GSN and MG-1. I had great results with metering. But I finally settled on a Lynx with a bad meter.

Sounds good, will give it a go. If I'm shooting slide I'll just pop a fresh one in. I might also try taping together 4 of the lr44 button cells and see how that flies too.

The main problem with using alkalines is that the battery check light may not light, even if the batteries are still providing adequate voltage for metering.

Monopix has an interesting article at http://www.monopix.co.uk/gtbattery.shtml comparing alkaline and lithium batteries for the Electro 35. The problem with the PX28A, the alkaline cell probably used most often in the E35, is that its voltage drops off to less than 3.9 volts under load. That's enough to work the exposure system, but not enough to trigger the battery check circuit. So the camera is usable, but you get no warning that the battery is getting too low to run the shutter correctly.

I have been using a cheap Chinese alkaline PX-28 as a test battery for at least 2 years now. That means that it gets installed in every camera that I receive for evaluation and repair. It still reads 5.4 volts. I also use the same batteries in my personal Electro's with excellent results.

Just FYI...

I use a Duracell 28A along with the "shotgun shell" adaptor. Works fine & battery check works as well.

They don't discharge in a liner way therefore your readings will not be accurate as it discharges.

To put it bluntly, that's crap. Try reading my article that nparsons13 posted a link to above.

As long as I have read (read - not tested myself) Electro 35's are pretty prone to voltage deviations. For 35 FC I still made adapter with Schottky diode, just a bad habit of having control over things (illusion). Or kind of exercise.
