I wish they made solar versions of the retro casios. :-!
I just asked this question a few months ago here on the thread and was told by a senior member that the CTL1616 is a battery and not a capacitor. Am I mixing things up?
So I was mixing it up after all. Many thanks for the extensive explanation. I was wondering about this the last time I asked the question and got surprised in this thread, but it all makes sense now.
