[rollei_list] Re: Batteries

Hi Eric,

  

My own conclusion after trying them all is either the CRIS adapter or
using silver oxide replacements and recalibrating to the higher (but
consistent and long-lived) voltage. I find the Z-O cells too short
lived to count on... often just about dead right new right from the
package...
    

I have come to the same conclusion about ZO batteries.  I won't use them.
But, I have found that simply "recalibrating" (which means different things)
to a higher voltage battery does not always yield the "correct" results
across the entire exposure range.


Some cameras, like the Canon EF, are simply plug and play.  The circuitry
has a wider tolerance for input voltage (some claim it has a voltage
regulator, but there is no proof of that, and I have the schematics and
circuit boards etc., and find no regulator, unless it is embedded in the one
IC in the circuit, which I doubt), and the meter readings are the same for
mercury or silver oxide, with no adjustment.

Regards,

Austin
