Safely charging my 65

That's why the Classic battery socket has three pins plus a spring strip to reconnect the calculator circuitry to the battery when the charger is unplugged. So there really shouldn't be a risk to the calculator from charging the battery while it's in it.

This makes perfect sense to me. Now that you mention it, I can see the spring strip down in the charger socket.

I agree completely, but I must say that I'm getting more comfortable since so many have kindly shared their knowledge.

Thanks,
Brad
