Overvoltage Damage?

[Jim Frame]

I was recently given a 41CX that belonged to a former co-worker, now deceased. Although appearing to be in pristine condition, it wouldn't turn on. The batteries looked good at first glance, but on further inspection I found that they weren't N cells, but rather A23 cells. Very close in size, but the latter put out 12v each, delivering 48v to the device. Looking through my own 41CV manual, I don't find anything describing the operational input voltage range, but I'm thinking that 48v is likely to be too much. Can anyone here verify, and possibly suggest which component might get fried? I'm wondering if the calculator is practical to repair.

Thanks!

I didn't reply earlier because I don't know the answer and I was hoping someone who did would pipe up; however, I can't imagine much of the electronics survived.  It would be kind of like plugging your 120VAC clock radio, blender, printer, whatever, in to a thousand volts or more.  If that's the case, various parts of the 41 could be used to restore other ones, like the case, battery holder, keyboard, maybe the LCD, and who knows what else.
