Tony, as chargers becomes more and more unreliable, do you know the best way to charge battery packs outside the calculator?
Yes, there are HP-docks for that, but I don't have any, but I'm thinking of building one for each type (mainly for Classic and Woodstock). Do you know of any schematics that shows how the charger is connected to the battery, I guess that there is some kind of protection between the charger and the battery?

Best regards,
Thomas

This is the best charging USB cable...
