But as you can see in the disassembly video, the batteries are AA-Cells you should be able to replace them with better ones.
Don't know why C.A. decided to use Ni-MH Batteries even in the newest upcoming release C.A. 5292 and C.A. 5293

It is not that bad if you use the meter on regular basis. If you use meter only occasionally, for instance you keep the meter in the box for few months, and then you expect it to have full bat, then you will not be happy. In which case maybe you should consider different meter.

There is an additional internal photo of the MTX3293 here that seems to show some further protection devices under a plastic cover

I don't see very well.  Could you please point out these additional protection devices.   No doubt there will be some sort of high speed clamps in various sections. 

Without the larger parts in both legs,  I can't see this thing holding up very well in the tests I run.  The tape holding the plastic cover down will be fuel for the fire.    It looks like ferrite under the pink heat shrink on the large ribbon.  Can anyone confirm?
