TI-84 Plus CE Battery for Texas Instruments,【2600mAh】 𝗨𝗽𝗴𝗿𝗮𝗱𝗲𝗱 High Capacity 0 Cycle,P11P35-11-N01 Battery,Part No 3.7L1200SPB 3.7V TI-Nspire CX II TI-Nspire CX II CAS

Wasn't hard to install if you've ever taken anything apart and got it mostly back together. Seems to be working fine and at a good price. It lasts long enough between charges. After installation the calculator booted up (no more failing boot loop) and showed a half charge. After a little recharge it was good to go back to school.

Worked perfectly for my TI 84 CE plus. The original battery died after about 2 years of use, and this was a very simple, low cost way to get the calculator back up and running again!

I cannot say thank you enough. These were clutch when sending my son off to college. They were a great price, easy to install, and saved me over $100 on getting a new calc. The battery life is great with these and charge easily. I was so happy that they were compatible with his calc. Box stores do not even offer these batteries. Thank you Amazon!

Model P11P35-11-N01 Battery, Part No 3.7L1200SPB 3.7V. Likely NOT 2600mah; probably only 1200mah as designated in the model “1200SPB” based on web research … ALL REFERENCES to the model number state it is only 1200mah. Don’t understand why it is listed as 2600mah … if that were accurate, the battery should be heavier than the original battery, maybe twice as heavy. This battery actually WEIGHS LESS THAN ORIGINAL by about 2 grams. That being the case, it is HIGHLY UNLIKELY TO BE TWICE THE CAPACITY of the original battery. Likely doesn’t rate 1 star, should be zero/0 star.

The old battery was bulging. The calculator would not start. This new one worked perfectly.

Working great

My daughter's calculator battery died and I tried ordering from a different seller, but the package when from being a few miles away to the other side on the US. I ordered this and it showed up in a few days. Just in time for her to use on the ACT. The battery replacement was easy and it fit like OEM.

My Ti 84 died and it wouldn't turn on and turns out I needed a new battery. This immediately made my calculator work again so I didn't have to spend another 100 dollars on a new graphing calculator. The battery life is good. I haven't had any issues with it for months os using it.

Llegó rapido y funciona bien

EXCELENTE PRODUCTO PARA LA CALCULADORA DE MI HIJO, ENTREGADO PUNTUALMENTE!!!

La batería funciona correctamente, la duración es incluso mayor que la original, pero algo a tomar en cuenta es que viene ligeramente más pequeña y no hace la presión suficiente sobre los pines de alimentación, lo que podría parecer que no funciona al ocasionar intermitencias en la pantalla, yo lo solucione colocando una pequeña calza de algodón para hacer más presión, y se eliminó el problema, claro que no debería ser.
