Good Replacement Battery for TI-84 Plus CE
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.

Great prodcut
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.

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

NOT 2600mah, instead probably only 1200mah … LESS CAPACITY THAN ORIGINAL
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.

A great tool for college math and beyond.
Got my calculator today, fast shipping. I read the other reviews about the bootloop and calculator not holding a charge, so I also ordered a new battery just in case I got a defective one. I unboxed and tried to power on the calculator (after removing the plastic ribbon from the battery compartment) and boom, got the dreaded bootloop. So being prepared, I removed the battery cover, cleaned the contacts and re-seated the battery. Voila! The calculator powered on with no issues and battery was at 75%. A small piece of the plastic was covering the contacts preventing the calculator from powering on. It charges and works fine and I am happy with my purchase. And I have a spare battery just in case the original fails.

Don't buy name brand when this works
Best choice when Amazon's competitor wouldn't honor their product warranty for the original calculators previous battery failure. Battery quality is tops and it was easy for me to install and use

¿Falso contacto?
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.
