I bought this for my TI-Nspire CX CAS because I was tired of the low battery warning popping up right in the middle of exams. It's a lot more cost-effective over time compared to buying packs of Duracell batteries

I was skeptical about the price at first, but it pays for itself within a semester. The installation was straightforward, though the screw is tiny so be careful not to lose it. Battery life is solid—I get about two weeks of heavy use in my engineering classes before needing a plug-in. Much better for the environment too.

The battery performs as advertised, providing reliable power for the TI Nspire. However, the price point seems a bit high for what is essentially a standard Li-ion cell. It’s a necessary upgrade if your current one is failing, but don't expect it to "transform" your device.

My old battery was basically dead after 4 years of heavy use in engineering school. This one fits perfectly and honestly feels like it holds a charge way longer than the original one did when it was new. Total lifesaver for finals week!

I purchased this as a replacement for my students' calculators. The installation was straightforward, though you do need a small screwdriver. Compared to the third-party knockoffs I've seen, this official TI battery provides much more consistent voltage levels. It has significantly extended the lifespan of the CX units in my lab. Highly recommended for any long-term user.

It's a standard OEM replacement. Pros: it actually fits and won't swell like the cheap ones from eBay. Cons: it's a bit pricey for what is essentially a small Li-ion cell. I haven't noticed a huge difference in "upgraded" capacity compared to the stock one, but at least my Nspire doesn't die every two hours now. It's a necessary purchase if your old one is toasted, but don't expect it to turn your calculator into a supercomputer.

Honestly pretty disappointed. The connector pin is super flimsy and I almost bent it trying to get it to seat properly. For the price TI charges for these things, you'd think they could make the build quality a bit more robust. Plus it didn't even come fully charged.
