Stable performance: high charging efficiency, small self-discharge. Rechargeable batteries that can be recycled multiple times provide a reliable, long-lasting power source for your calculator.

Review: Replaced my old battery and popped this one in. No more issues and the charge quality is the same if not better. Great battery life. Very easy to install as well. And it fit into the calculator with ease.
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 battery came partially charged, and they even included a mini screwdriver, which was a great touch. The price is very reasonable, and shipping was quick. The original battery lasted a little over a year, so we’ll see how long this one goes. So far, so good.

It solved the “validating OS” syndrome instantly. Came fully charged and with a tiny screwdriver, a plus if you do not have one. Relatively cheap and available on overnight delivery. Fantastic!
