[SML] Auto darkening helmets

[Jerry Durand]

This is a top-rated Northern Hydraulic...err...Tool one.  I just asked
them about replacement modules, no luck, my helmet is too old. 

I left it under a bright light from the time I finished welding,
showered, etc.  Needs to be under a really bright light just to darken
(I thought these were supposed to fail dark).

Out of curiosity I popped the module open.  Two CR2330 cells.  One's
only reading 0.5V so I guess I could try replacing them as a first try. 
I'm surprised they're not rechargeable or just a big capacitor.
