TI-84 Plus CE Battery,[2025 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

Battery works perfectly fine, comparable to OEM.

Perfect fit! Still working after several months.

Perfect replacement, good value.

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.

Easy change and working great and good price.

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.

Great price and delivery

Battery is not fully charged. I don’t know if it was used in returned or what. They should be tested before there’s sent out.
