Any oneelse?

Anyone else have the same battery in their calc since level 1, im having a seinfeld moment and wonder if i should change it and risk it crapping out due to a bad batt or just hope it makes the next 2 weeks, bts its been 4 years.

No brainer - change it.

My enter button is starting to not “enter” the numbers I put in sporadically. I think I will get new one before the exam.

i have the same 12c, same battery - the 7 button is starting to sputter out

just changed mine last week
