TI-84 Plus CE Replacement Battery for Fits Texas Instruments TI-84 Plus CE P/N:P11P35-11-N01/3.7L1200SPB 3.7V [1600mAh] with USB Charger Cable

Exactly as described and fits properly. Great price

Fits and works. Not much else to say.

I could only charge it like 3 times before it stopped working. I had to buy another one.

Purchased this replacement battery and calculator works like new. I thought I was going to have to buy a new calculator, but this battery did the trick!

Six years. That’s how long my TI-Nspire CX calculator had been faithfully crunching numbers, graphing functions, and surviving countless exams and late-night study sessions. But recently, it started showing signs of fatigue. The battery had grown moody—sometimes powering on, sometimes refusing to cooperate, as if it had developed a personality of its own. I knew it was time. I ordered a replacement battery, hoping it would breathe new life into my aging device. When it arrived, I was pleasantly surprised by how simple the installation was. No tech wizardry required—just a small screwdriver and a few minutes of patience. I opened the back lid, unplugged the old power cable, plugged in the new one, and closed it up. That was it. No drama, no fuss. And then came the moment of truth. I pressed the power button, and there it was—my calculator lit up instantly, as if waking from a long nap. It felt like I had rewound time. The screen was sharp, the response snappy, and the battery? Solid. Reliable. Ready to go. Recharged well! Replacing the battery didn’t just fix a problem—it restored a tool I’d come to rely on. If your TI-Nspire CX is acting up, don’t hesitate. A new battery might be all it needs to feel brand new again. Viola! You’ve got a fresh start.

Took a charge 4 times. No longer charges or holds a charge. Battery life terrible. Purchased on 8/11/25 went bad 9/10/25. Missed my return window by 1 day.

Fácil de manejar. Solo que la pila se dañó y el proceso de cambio es tardado.
