Logitech had a solar keyboard (K750R) and we used them heavily at work as they were amazing to type on.. we had thousands of them. We also had dark rooms and they wouldn’t get enough charge to stay charged forever. They also used a weird rechargeable battery the same as a CR2032 which is incredibly hard to come by

Huh, admittedly more expensive, but if it is just an LIR2023 I'm seeing those readily available on Amazon.

This would have been like 10 years ago.

Ah, gotcha.

Edit: and it uses an ML2032 also.
