[rollei_list] Rollei 35 meter battery

Fear not, worthy campers. The Rollei 35's all work well with alkaline batteries and the difference in voltage is not sufficient to cause a problem even with chrome emulsions, though the drop-off rate is severe enough to warrant frequent replacement. Silver oxide cells can be used but these are smaller in dimension and you probably would do well to use shimming carved from scrap plastic with your Swiss Army knife or the like. You can pick up the CRIS adapter or use a hearing-aid battery, again with shimming, and these will preserve the 6.35 volt output, though those hearing aid batteries have a viciously short life. And PX625 cells are still available new as they remain in production in Red China and the "bweela SSSR". FINDING them can be a problem, but they are out there.

A more elegant solution would be to install a bridge circuit to allow the use of alkaline cells while reducing the voltage from 6.5 volts to 6.35, but this seems a bit of overkill. It CAN be done -- most European cameras using PX 625's came with such circuitry -- but it is a bit complex.
