I have just put 4 SR44 silver 1.5v cells into the battery holder and placed it into my (new) 35GT. I appreciate that this is 6v as opposed to the original 5.6v mercury original. When I press the battery check button the needle drops smartly to the area UNDER the 30th sec marker. I have checked the cells polarities. The original manual states that a mercury cell would give a reading of 125th sec on battery check. Is my new reading wrong? What degree of compensation should I be making in terms of ASA values? The serial number puts the manufacture year as 1981.
Many thanks. |

Have you insulated the battery chamber? My Minox 35EL has a metal battery chamber which will short individual cells and give strange results (as well as damage the batteries). I just cut a piece of paper to the appropriate size, rolled it into a tube and stuffed it in and solved this problem.
I have gotten acceptable results this way; for best accuracy I've recently tried using 4 ZnAir cells, but I don't know that this makes any difference. |

Thanks Rick. The battery holder is made of a plastic tube with side slits. I have just tried re-seating the batteries and am now getting a more acceptable reading of about 250th sec. Well, it seems more promising than the 30th sec before!
Does this sound about right considering the higher voltage? |

yeah, that probably makes sense. backing off the ISO setting won't be perfect, as you will have more error in brighter light, but if you're shooting print film i would adjust the ISO to give you a correct exposure in sunlight... then at lower levels the error will tend toward overexposure, which the film can handle within reason.
