are 6.2v batteries okay in a yashica electro 35?

[adam_n.1]

i've been using the alkaline 4LR44 batteries which work fine but are

6.0v. i'd like to try using the more reliable silver oxide 544

batteries which are 6.2v. that extra .2v won't pose a problem will it?

Adam-

 

 

If I remember right the original battery for my Yashica electro 35 was a 5.6V.So using the 6V,(which I'm using now) the shutter might be running a tad slower(?)I don't notice any difference) another.2V won't make that much difference-imo,besides I usually shjoot TriX

in this camera anyway-but I'm no expert- just telling you my experience

[don_mckeith]

I'm gonna re-think that-

 

higher voltage= the shutter a tad faster(I think)

The Yashica workshop manual gives 4.5-6.5 volts as ok

thank you roger.

 

don- it's my understanding the electro 35 has a voltage regulator (or whatever the proper term is) and that there is no need to compensate for overvoltage. so thankfully i don't think you have to worry about the shutter speed being off!

The E35 does NOT have a voltage regulator. But the light meter circuitry is quite complex and not just simply a photo resistor and a galvanometer switched in series - as on many older cameras, and this kind of circuit IS voltage sensitive. The E35G circuit is more or less self-compensating, i.e. less sensitive to supply voltage variations.

 

I once ran across a web site where a guy had run a computer simulation for the E35G light meter circuit and found out that there is less than 20% (less than 1/3 f-stop) shutter speed variation over a supply voltage range between 4.5 and 6.0V.

Personally I got a convertor from yashica guy to fit lr 44 type batteries with a gizmo for altering the output. The results are just fine.

I second that. The www.yashica-guy.com 's battery adaptor is the best solution. I have several mercury batteries but I just use the adaptor. Tomorrow I'm going to buy a Vivitar 285 HV for my 3 Electro GSNs. I still haven't tracked down the 57mm slip on lens hood. The 55mm screw on blocks the rangefinder a bit. Maybe I should trim the hood. I love these Electro GSNs...I got kicked off nikonians.org for my Electro posts even though I use my Nikon FM2T for professional work. (That's going to change on my next wedding gig.) :-))
