How to change Battery on Canon F-1 and use adapted Type 675 batteries (instead PX625) with adapter

Buy it here: ausgeknipst.de...
With the included rubber O-ring, those Type 675 hearing aid batteries perfectly fit inside the battery chamber of a Canon F-1 classic. This makes them a perfect replacement for the old PX625 mercury batteries that are no longer available.
The batteries that are included are based on Zink-Air and don't distort the measurement of the light meter, since they offer a constant ~ 1.4 V current until complete discharge.

is it safe not to remove the lr44 when the camera is not in use (especially for a long time)? because my camera battery cover is broken so it can't be opened

[@ausgeknipst]

Yeah, its safe :) No worries.

Nice tip. Thanks

You're welcome 🙃

I saw in the videos that they use 625A batteries with 1.5V for FT/FTb models etc. and it works without overvoltage.
So what battery should I use?

[@ausgeknipst]

Not sure what your question is, but as far as I know the Ftb used Mercury batteries with 1,35V, so I would use hearing aid batteries (e.g. the ones we sell) for accurate metering.

Thank you for your video. How how long these earing batteries last?

[@ausgeknipst]

Depends on the use. From 3 months up to a year.

Question man , i have a canon ftb I’ve put on this battery with the o ring on it . Would i have to adjust my iso down a stop or is it accurate not to move and leave at iso the film is asking for . Hope to hear back from you soon man .

[@ausgeknipst]

The batteries have the proper voltage so you do not have to compansate with the ISO (if your light meter works the way it should).

@@ausgeknipst thanks for your help 🙏🏽

[@Gillerz100]

apologies if it's obvious - but why does this camera need a battery? I thought it was mechanical

[@ausgeknipst]

Hey, it works mechanically but needs a battery for the light meter. Greetings Vlad

There is a prism finder for F1 that has shutter priority with some lenses and a special lever, but it has other bateries. And there is another finder buster that adds light for setings in viewfinder and longer exposure times, but also with other batteries.

Anyone know where I can get the ring from? The link to his store is dead?
