Mercury battery substitutes

I use some Kanto MR9 adapters, with Leica M5, Leicameter MR, Yashicamat 124G, Canon F-1n and FTb QL, Zeiss Ikon Icarex 35 STM, Canonet G-III QL17 and all work very good, in conjunction with 386 silver oxide batteries.
Ciao.

I've been using a wein cell in the M5, and I told DAG to leave it that way since he's servicing the camera now. I don't trust the alkalines because I've seen them drop incrementally over time so one can't really know when they are going off.

I have adapted batteries that are too small for whatever device - If you have a drill press, it's pretty easy. Get some aluminum rod stock of the appropriate size at the hardware store. Put it in the drill press. Using a hacksaw, or a file, or the like, simply cut off a piece that's the right size to make up the difference. I've done this for several devices and it works great.
 
675 batteries and a rubber #9 O-ring sold at ACE Hardware. EOT!
Next Thread please.-Dick
 

You can use 1.5 V alkalines in the EF with no problem as it has a built in voltage regulator. The F1 does not.
