Out of curiosity I searched and found the S76 battery is available. Why wouldn't you use it? I'm unaware of the reason don't give me grief just explain if you would.
The silver oxide versions cost a little more, and they are somewhat harder to find -- but in my opinion, they are worth the extra cost and effort. I would encourage everyone to buy S76 or SR44 batteries whenever practical, in the hopes that continued demand will keep them in production.Out of curiosity I searched and found the S76 battery is available.

Just now, I almost bought a used Konica FC-1, but when I asked for a photo of the battery tray it showed the old LR44 batteries still loaded, and green corrosion forming at the contacts. The seller was unwilling to test it with fresh batteries, and she does not accept returns, so I did not buy the camera.
Would the use of SR44 batteries have saved this camera? I don't know.

In 2021, I bought a used Konica Autoreflex T4, and in 2022 I sent it to Greg Weber. He recalibrated the meter to work with modern batteries. At that time Greg Weber was recommending the use of S625PX (silver oxide) batteries for my re-calibrated camera. Due to a chain of mishaps, misunderstandings, and bad luck, I did not get my camera back until August 2023. By that time there were no silver oxide batteries available in the S625PX size. None.
The correct size batteries for my Konica T4 are still available in the alkaline chemistry (PX625A and similar), but not in silver oxide. I decided I would rather use the smaller silver oxide S76 or SR44 batteries in a (dumb) adapeter to make them fit -- as opposed to using the correct size in the alkaline chemistry.
Greg Weber says the camera meter will work correctly with either type chemistry:
"The alkaline will work but they will not last as long. Example: if a silver lasts 18 months you can expect the alkaline ones will last about 8 to 12 months. But starting voltage is the same on both kinds. The T-4 use’s so little voltage, so unless you're keeping the camera on all the time, the silvers are not needed..."
However, due to the increased possibility of leaks with alkaline batteries, I prefer to use silver oxide wherever possible.
Thank you.I was under the impression the OP was having trouble sourcing S76s. If not, you're right, just use those.
I found it on Amazon fairly inexpensive.

I don’t want to be obnoxious, but the last 2 times I ordered silver-oxide batteries on eBay or Amazon they were returned. No good. We had a good battery store in the neighborhood but they closed. Now it’s a 20 mile drive but I know I can count on them to have good batteries.
Alkaline batteries slowly lose their voltage over time. A small difference doesn't matter much but, if you don't catch it in time, it will typically give you increasingly faulty meter readings.
Silver Oxide batteries are this strongly preferred because they hold voltage until they "fall off a cliff". Another option is a CR1/3N lithium battery that replaces two of these i one stack.
