The question is....

At just what temperature must the batteries rise to before the system resorts to the use of A/C for cooling them.

Does anyone know for sure what type of battery is used in the FEH/MMH?

Buying a small battery of the same type and charging it fully and then using a constant load to see how it holds up "frozen" versus room temperature is a simple enough task.
