Here is a chart of all automatic pack film camera models and the batteries they take. Use this to determine what mods are available to your particular model. The options correspond to the voltage requirements as well as the amount of available space. You can always send your camera to me if you are not up to the task.
I have documented the reconditioning and modifications for the two different battery types. The mod is the same for any model that takes the same voltage and number of batteries.
4.5v to 3xAAA conversion
3.0v to lithium conversion
3.0v (x2) to lithium conversion
(electronic development timer)
The bold models are the examples used.
