HP-25C It’s alive!

[John Garza (3665)]

On the 'never a problem' post. The issue with the Woodstocks happens only under certain conditions when the battery pack goes bad, is not in place, or there is some slight corrosion that keeps the battery from making good contact. Zero corrosion batteries with shiny contacts in the calculator should work fine - that's what it's designed to do. The issue happens over time when the battery starts to fail, or makes poor contact. Never charging a battery in the machine is essentially a safety procedure. Like always stopping at a stop sign when you're driving. Corrosion and battery failure will eventually set-in if you use the machine regularly. So even if it works now, there is no guarantee it will work a few years down the road. And following the safety procedure could save your machine.
