1,5V A1PX (PX1A, 1100A, PC1A, 1A, EPX1) battery

Many super 8 camera owners have the problem of not being able to get their hands on mercury batteries that are responsible for feeding the light meter circuitry. These Mercury button cell batteries aren’t produced anymore, mainly for environmental reasons. Nowadays their are replacement batteries that provide slightly different and allow Super 8 camera users to still shoot in automatic exposure control mode, albeit with slightly different light meter readings.  These slight differences should not have too much of an adverse affect on automatic exposure control results.
We offer these batteries here as one of the only alternatives readily available for those wishing to use a camera that requires button cell batteries.
