A problem with Casio FX-92 battery?

Hello,

I changed the battery in my Casio fx-92 calculator because it wasn't working anymore. Despite the battery change, it still doesn't work. Is there something I did wrong?

Configuration: iPhone / Safari 14.0.3

Hello,
Have you inserted the new battery the right way round (+ on the left, - on the right)?
Did you follow the replacement procedure correctly?

Very difficult to catch a black cat in a dark room.
Especially when it's not there...

All that has been done, thank you! :) But that doesn't work after all...

And silly question, it's the new battery that has been put in place ... ?
Try another one. It happens that batteries, even "new," can be faulty or too old (check date).
