Solid replacement
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.

Excellent Price, value, quality and even included a screwdriver!
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.

Keep on calculating!
Daughter’s calculator died after two years. Great value to replace. Works great for a fraction of the cost of a new calculator. Quality battery. No complaints.

Solves the “verifying OS syndrome”.
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!

Works as expected

It added up
Easy to swap... We kept getting crazy recycling screen, looked it up and it said dead battery. I was skeptical, but a few tiny screws and kaboom... Works again... A lot better than buying a new overpriced calculator

Great price and Good battery
My Texas TI-84 Plus CE was doing that glitching thing. I bought a new charger to see if that was the issue and it wasn’t. I saw online that you can buy a new battery and it could fix your calculator. It was a 50/50 chance. I honestly didn’t think it would work but it did. They also give you a little screw driver to open your calculator. The price is great for the battery. I happy with my purchase! It’s so easy to put the new battery in and it fit exactly like the original battery.

Life Saver
My Ti84CE calculator battery died on me right before this, causing my calculator to go through the OS loop just two days before my exam. This battery was a lifesaver, came super fast and was a perfect fit for the calculator. Charged up pretty fast and works great. Unsure about battery life since I haven’t used it for extended periods of time yet.
