Finally acquired a Woodstock

But again, if you say you can operate the calculator only 3 hours from a set of freshly and correctly charged AA Eneloops there definitely is something wrong. This would mean that the device constantly draws a current of 700 mA (!). How do you charge these batteries?

Well, the batteries were recharged but unused for several months which may have affected total capacity. Also, not exactly a stock HP25, as evidenced by the IR diode at upper right. I had the ACT replacement configured for full speed, internal ROM as I worked my way through all of the on-board Application Program examples, making occasional program listings. Not sure what the IR diode current draw is, but it has a decent print range.

The calculator went a little wonky just past the two hour usage clock mark, which I (perhaps hastily) interpreted as time for a recharge. I charge the batteries with an external Panasonic BQ-CC17 charger. If given a vintage wall charger, I'd heave it as hard as I can, as far away, as possible
