Printed inside the AA pack and in the instruction manual it reads "Do not use Ni-Cad cells."
I'm familiar with the concept of a known voltage being used as a reference for metering and shutter operation and can usually compensate for higher or lower voltages in the ISO/ASA settings and I'm wondering if incorrect exposures is the only reason I'm being warned off Ni-Cads?
Is there anything about the characteristic discharge of a Ni-Cad cell or anything else about it that could damage the circuitry of a 1989 camera? What about Ni-MH cells which have more-or-less completely replaced Ni-Cads now? Would it be safe to use much more convenient rechargeable Ni-MH cells or should I just stick with Lithium or alkaline?
Any thoughts appreciated.
