Calculator question

Does a ba ii plus professional calculator go off on its own when it is idle?

havent touched my calculator in almost. 2 days and when I finally went for it it was on. I’m scared I’ve used up all the battery life

Mine does turn off after a few minutes of not being used. Are you sure you didn’t press the on button when you grabbed it?

just bring new batteries as insurance to the testing site?

^ don’t waste your time.

change to new batteries a week before the exam. use it to practice with for a whole week, and don’t bother worrying about changing batteries during the exam.

buy a 2nd calc then return it after the exam

Thank you all
