MessageHi Jeff. Some time ago I bought some mercury cells from China and unlike the original cells they had a no basic voltage of 1.5V instead of 1.35v. The vender suggested that I short the cell briefly to bring the voltage down !! ?? Again, you can consider hearing aid batteries although the zinc air dissapates after a time. never the less they retain the origianl voltage better over its life span and is reasonable like about $1, or less, each when bought in packs. I note in eBay the good 35's bring fair prices.

I fear that the always-on meter of the Rollei 35 might have been designed with the assumption that long-lasting mercury cells would be around in the future. -----Original Message----- From: rollei_list-bounce@xxxxxxxxxxxxx [mailto:rollei_list-bounce@xxxxxxxxxxxxx] On Behalf Of Roland Smith Sent: Sunday, September 24, 2006 3:01 PM To: rollei_list@xxxxxxxxxxxxx Subject: [rollei_list] Re: Rollei 35 meter battery I can't vouch for the life of alkaline/manganese batteries. I have mercury batteries in all my Rollei 35s and have never had a battery run down. I always keep my Rollei 35s in the zippered leather case, zipped up, except for the brief moments in use. It is possible that when the lens is collapsed, the meter may not be on. I do not know about the collapsed lens turning off the meter.

Is that the case, and how long is the battery life of an alkaline/manganese battery in the camera? Jeffery Smith New Orleans, LA http://www.400tx.com http://400tx.blogspot.com/
