CASIO FX-880P battery replacement as a test of the Xiaomi A2 Lite camera

Yep! I just recorded the replacement of the three batteries of my 25 years old scientific calculator, using the Xiaomi A2 Lite smartphone's camera.
Looks good, doesn't it?

Why it is not starting like mine

[@ct7afr326]

Probably due to different settings, no?
What do you mean exactly? How does your calculator starts?

Yes

Sorry for my very late answer (I didn't see your comment/quetion). Anyway, here goes:
According to the operator's manual, You should replace first the CR2032 batteries and then the backup battery (CR1220).
If you take all batteries out of the computer at once, you will loose your programs.
