Old battery was damaged and was worried the calculator itself was damaged, but it was as good as new when I put it in!!

Popped the battery right in the calculator and started working instantly. I had ordered another battery off of amazon before that didn't work, but this one fixed it right up. I appreciate the mini screwdriver that came with the order as well. Completely satisfied!

This battery is all I needed to revive my daughter’s calculator. Funny I looked up what could be wrong and it said batteries typically last 3 years. She got it as a freshman at the beginning of school and it died her first week as a senior. I figured let’s buy a battery and see if it works. 3 months later and still working good as new.

A good replacement battery for most Texas Instrument calculators, shipping was very slow and it got delayed but the product works fine

Son's Texas TI-84 Calculator stopped working that he has had for year's while away at college. Ordered this battery which included the small screwdriver and sent it to him at college. He switched it out and it started working like new, now issues since. So happy we did not have to spend money on a brand new calculator. They are so expensive!!
