Interesting that the cr2032 battery is not rechargeable, so is the solar panel real? Or does it bypass the battery and use the solar panel in lighted situations?

The guide should specify that the CR2032 needs to be rechargeable. They are readily available at a popular online shopping website. I was skeptical that the solar was real too, because of the frosted plastic placed over it. Based on the pictures in this teardown, and another video showing a red LED in the solar circuit, I conclude that the solar charging circuit is real.

The manual doesn't specify a rechargeable battery. It just says a CR2032 Lithium battery. Unless all such batteries are rechargeable? I guess I'll find out since I just replaced the battery in mine and it's an Energizer CR2032, but it doesn't appear to say rechargeable anywhere on the packaging or the battery itself. I guess if it kills my calculator, it had a good run....

EDIT: The original battery that I took out of the calculator doesn't say rechargeable on it either.

Marc W -

good guide, I'd just like to add that in my case I needed to press the "Reset" button for my calculator to start up again

Greg B -

yeah but I have done that 3 times and now my calculator is officially announced dead....
