Yashica Electro 35 GSN Battery Options

The Yashica Electro 35 GSN and the MG-1 are fine rangefinder cameras. If you've wanted a Leica M version rangefinder but don't want the high price then you can consider the Electro 35 or MG-1.   

The big problem with both cameras is the battery which is no longer available. The original battery was the mercury 5.6V Mallory TR164 or Eveready E164

Although both cameras work without a battery you really get the value of Auto mode, the light meter and shutter speeds with a battery. As such, you have 3 options. They are:

• A 6 volt similar sized PX32 styled alkaline battery
• Stack a CR123A / LR44 battery for 4.5V
• Use an adapter with 4 x LR44 batteries for 6V

I've tested all 3 versions, and all 3 work. The light meter compensates voltage from approximately 4.5 - 6.4V. Therefore, all 3 options work without negatively impacting exposure.  

Here is how you stack a CR123A / LR44

Both batteries are readily available and this is a simple solution. I shot a roll with this battery setup and it worked fine.

The test battery setup was using an inexpensive adapter that I purchased on Amazon with 4 x LR44 batteries for a total of 6V.

Either option that you use provides good results for your Yashica Electro 35 GSN or Yashica MG-1
