JBonner Posted August 21, 2007 Share #1 Posted August 21, 2007 Advertisement (gone after registration) I have a Leica CL which has had a recent CLA and adjustment to take 1.5 volt batteries. At present it is fitted with an alkaline battery which appears to function OK, although I am aware that the voltage is not as stable as the original cells. Is it possible to change from an alkaline battery to a silver oxide type without further adjustment of the meter? I also have an SL and a Luna 6 which both take PX625 and my stocks are running low so this query also covers these items. Any advice gratefully received as always Link to post Share on other sites More sharing options...

doubice Posted August 22, 2007 Share #2 Posted August 22, 2007 John, I assume that by 'adjustment to take 1.5V batteries' you mean that the camera had a Schottky diode (resistor) installed into the meter circuit. This will reduce the voltage from 1.5 to 1.35, which was the voltage of the original Mercury based PX625. If this was indeed done, I would recommend that you definitely use the Silver Oxide PX625. Alkaline battery voltage drops gradually, while the Silver Oxide variety holds its voltage more evenly towards the end of its life. Best, Jan Link to post Share on other sites More sharing options...

doubice Posted August 22, 2007 Share #4 Posted August 22, 2007 look at myoldcamera.com.Jan This does not address John's question. "myoldcamera.com" sells Zinc-Air based Wein cells, which are to be used in cameras that were not modified for 1.5V batteries. John's CL was already modified and using a Wein cell would not provide correct readings. John's SL and Lunasix, if still unmodified, could use the Wien cells. The only drawback is that once activated, they have a relatively short life. There is a relatively simple way to convert the SL and re-calibrate it for the Silver Oxide PX 625 unfortunately, I can't find the web page with the information..... It was published by Doug Herr, who is a frequent contibutor to the Leica Forum and I might have saved the info on my home computer.......

garyp Posted August 24, 2007 Share #5 Posted August 24, 2007 Used these for years in my SL bodies; had zero problems, but some folks have problems with proper fit...YMMV CRIS Camera:Test Instruments Link to post Share on other sites More sharing options...
Artorius Posted August 24, 2007 Share #6 Posted August 24, 2007 I use the CRIS MR-9 in my Leica MR-4 meter. Good life, cheap batteries, no problems with fit. Used these for years in my SL bodies; had zero problems, but some folks have problems with proper fit...YMMV CRIS Camera:Test Instruments Link to post Share on other sites More sharing options...
