When I found my first "Woodstock", an HP-25, on the flea market some 20 years ago, I was lucky because it came without a charger. Although I was already a registered member of this forum then, I had not yet come across the warnings regarding charging these without a battery. Maybe there weren't as many warnings on the forum back than compared to the last years. And because I had never encountered this issue with any other calculator I would probably have plugged in the calculator the very minute I came back from the flea market...

It is absolutely not the fault of the people who destroy Woodstocks by charging them without a battery (or with a bad battery in place), but entirely the fault of HP for designing such crap charging circuits. With every calculator that came before and most calculators that came after they demonstrated that they can do better.
