Review: My son’s TI-84 got the dreaded OS error, and after researching fixes, someone suggested replacing the battery. This one did the trick—the error cleared, and everything has been working fine.

The original battery lasted a little over a year, so we’ll see how long this one goes. So far, so good. ## Features - Compatibility: Please open your calculator to carefully check the compatible battery model and part number before purchasing.
