TI-84 Plus CE Battery,[2026 New Upgraded] 1600mAh Fits Texas Instruments TI-84 Plus CE,TI Nspire CX/CX II、TI Nspire CX CAS/CX II CAS,P/N:P11P35-11-N01/3.7L High Capacity Battery

It was exactly as ordered and arrived as advertised. It was a plug and play battery that allowed the calculator to work immediately.

Works great with my Ti-84 plus CE python.

Bought yesterday, I installed today into my daughter's three year old TI-84 Plus CE calculator (which was stuck in the dreaded "Validating OS" infinite loop) and it was up and running in a few seconds. You do need a micro Philips but very simple and easy to do. Also was able to update the OS with TI Connect since it was finally stable. My daughter graduates in three weeks so well worth not having to buy a new calculator just for final exams! It is important to note that if your battery is less than two years old, TI will send you a new one if you go out to their support website and submit.

Worked as advertised. It fit. It holds a charge. It restored operation. It's a battery, so I don't know what more to say. Batteries either work or they don't. This one worked properly.

Easy change and working great and good price.

Great product.

Exactly as advertised, works just like stock.

Thank god for these when the calcs loop
