Worked perfectly. Swapped out with the old battery and the calculator fired right up and held a charge for a long period of time.

Great for old calculators that has depleted battery life
This brought new life into my TI Nspire CX CAS. It was super easy to install, and it fit perfectly into the battery compartment of my calculator. Its battery life seemingly doubled and it functions and charges no different to the original battery.Overall, if you have an old calculator and it needs new life, this battery is a must!

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.

Works and fits into my TI Nspire (the type pictured)
Works great! Fits great! Bought it when troubleshooting a fairly new calculator. In the end, I needed to erase the software and calculator memory and reinstall the software. I kept the battery as a spare because it works and fits.

Useless
They worked for 20 days. Then for ten days they occasionally worked without being plugged in. Now that the 30 day return period is expired, they only work when the calculator is plugged into the wall. Opposite of how a battery should work. Wate of time and money.
