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/For 3.7L1200SPB High Capacity Battery

the original calculator cannot work due to the bad battery. But this one for little cost and make the calculator works again. Have to complaint that Texas Instruments original battery is of such low quality.

Use this everyday needed a new battery for mine after I bought it but has been perfect ever since.

This battery saved me from buying another calculator before my final exam, this battery is also way cheaper than the manufacturer website!

It works as expected but the packaging is concerning for a lithium ion battery it was just 1 cardboard box and the battery in a plastic bag luckily I live in a small town and did a bulk Amazon order so it was boxed with other items keeping it safe

My calculator wasn’t turning on. I purchased a new charging wire, but the old battery no longer held a charge. I purchased this battery and my calculator instantly turned on.

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.

This battery didn't work for me. I needed it to come charged enough to start my TI-84, and it didn't. The calculator wouldn't turn on with this battery. I haven't tried charging it though, but that may not even be an option since apparently the TI-84 is very finicky about charging a battery.

This battery came fully charged, which was a bit of a surprise. In my experience the unfamiliar brands of lithium ion batteries are very risky to buy. Many times they come fully discharged, and it damages this type of battery when they are kept fully discharged for prolonged time. Often they do not charge at all and I end up having to return and try a different brand. This one looks a bit cheaper than the original but it fits perfect and works perfectly. It has the same part number as the original that came in my calculator, but as the description indicates, it is higher mAh so it will last longer between charges.

Battery saved at 75% (received with 75% over 2 days. My previous one lost app its charge in 2 days.Major improvement.
