HP82143A Powering a 41 _Extend Your HP41_

[rprosperi]

Greetings Diego! As usual, you bring interesting and good news to those of us that still keep working 41's at hand.

I am interested in getting a couple of these, after Massimo's 2 and Sylvain's initial dozen.

As the BAT annunciator cannot work, what is the expected end-of-charge behavior, unit simply does not appear to power-on, or lighter LCD contrast, etc.?
