Hi All,
Can someone do us a favour by writing a brief report on the replacement battery for the Yashica TLR? I have gone through the Internet and I am still a bit confused what would be the best option. I am using the Wein Cell Zinc-Air MRB625. Some said this battery has a very short life cycle (1 month) and some said it can last up to 12 months. Some said that by covering some of the tiny air holes may also prolong the battery life. Whether this is a myth or not I don’t know. I like to leave the battery in my camera battery compartment even if I am not using it but then I am worry that such battery may leak and cause corrosion. Other said that try hearing aid battery with a ring adaptor and it also works well, as such batteries are cheap and much easier to buy, but again, it may only last up to 6 months. www.paulbg.com/Nikon_F_meter_batteries.htmOthers also said use the Kanto camera mercury battery conversion type MR-9 H-D adapter with Panasonic SR43 SR43P battery 1.55V. Another adaptor is the MR-9. I am not sure what battery do you use here. I guess if anyone who had experienced any of the batteries here would like to share it with us? Such topic is very useful and benefit to any new potential members who would like to go back to TLR photography. Again, thanking you all in advance. P/S – All those comments that I read on Internet are not all related to the Yashica cameral as I understand that those PX625 and EPX-13 batteries were also used on many other cameras too. Apology if this topic has been raised before as I am unable to locate this topic specifically related to the battery for TLR on this site. |

Yes, you can cover half the holes in a Wein cell to make it last longer, but that varies. They can leak, but it's not as corrosive as an alkaline cell. The MR-9 adapter is the way to go as the SR43 cells are readily available, and last longer than a Wein cell with a degrade curve much like the original mercury types. And any information on batteries is easily transferred to any camera, as batteries are batteries, they don't act differently in different cameras (although some cameras will have a greater power drain due to their requirements).

Hi All again,
Thanks ridgeblue99.
One more question for the Wein Zinc/air battery.
On the positive side of the battery it has this sticker which it needs to be removed for it to work.
However on the other side of the battery it has a small foil and underneath the foil, it has this tiny metal bit and then a small patch of glue (black in colour) to hold these two parts together. I believe this is on purpose to ensure the battery has certain thickness to suite it can be used on some cameras. This this correct?
Therefore, my question is, for the Yashica Mat 124G TLR, do I have to remove this foil and the tiny metal bit or I have to leave it for the camera?
Any one?
Thanking you all in advance again.

Since it was put there to make the cell match the original in size, it would stand to reason that it will fit in all cameras that take 625 cells. It's just a sorry, cheap way for Wein Products Company to fix a design screw-up on their part.

Update:
It's exactly one year since I bought the Wein Cell Zinc-Air MRB625. Took two rolls of 120 films in October 2018 and then in July 2019 with my 124G. When it's not in use, I removed the battery from the camera and covered up all the 4 tiny air holes hoping to prolong it's life. Tried to use it again on the same camera few days ago and it seems that the battery is completely flat now.
It's disappointing. I am not a regular user with my TLR but having a battery runs out that fast is frustrating.

An observation on using Zinc Air hearing aid type batteries. I've tried them in Konica 'T' bodies, and have noticed the limited lifespans they suffer from. If they're used in the devices they were originally designed for, they probably work very well, and are certainly cheap enough to buy them in bulk packs when you'd be using them 2 at a time, and for very long periods over the course of their always-on use for hours and hours every day of the week. In this context I'd call 'always-on' to mean both, activated when the seal is removed, and active for the straight 8-12 hours they'd be powered on for a working, active, adult. They seem to work well for metering in the Konica's without being too far off in values. The problem as you've noticed kai , is in using them as light-duty short term power, over a far, far longer period of multiple months, instead of a week - or two, or three - for really heavy-duty use when freshly activated for hearing aids. The good news, if there is any, is still the low cost for an occasional outing. That might not hold true if you shoot often and go through them like candy. |

I've given up on Wein cells.

There are several options for cameras that use old batteries. I won't repeat what has already been said. Each has its pluses and minuses. I use a solar button cell recharger. These are still being made. A pretty good summary of options can be found on the SUBCLUB at: www.subclub.org/shop/battery.htm |
