Reason for need: My TI battery was the original battery and kept its charge about 3-7 days with some significant decay when not in use.PROS: Very easy installation in TI-84 Plus CE Python calculator. As far as I know, all TI-84s with replaceable and not-AA batteries have the same battery and access cover. Hence, I used a Stanley 2.4mm Phillips screw drive (3" or so tall) but I could have used a 2.0mm Phillips screw driver to unscrew the two (2) screws on the back of the calculator. Once the cover was off I used a Stanley 1.4 mm flat-edge screw driver to lift the battery out of its seating. I then inserted the new battery (goes in only one way!) and then screwed the Phillips screws back in.CONS: Nothing that I can determine except, as expected, I lost all data in the TI calculator.NOTE: If you have used the PRGM or other features of the TI, these areas will lose all of their storage and content. Hence, make sure you can take the time to refresh the memory and bring your calculator back to the way it was before you replaced the battery.Suggestions: Students: Replace much before major tests or between terms. Professionals: Replace so there is limited impact on your professional life. Check ALL areas of the TI for 'seldom-used' programs and features (TVM solvers, EDIT, PRGM areas etc.)I would definitely buy again. I will update if there are any material changes.

The calculator died right before my son's finals. Replaced the battery with this one and it works great. Hope it lasts longer than the original one, we will see

The DRECHAS P11P35-11-N01 battery for the Texas Instruments TI-84 CE/TI-84 Plus CE is a notable upgrade, offering a robust 2600mAh capacity that extends device usage. I appreciated the seamless compatibility and easy installation process, ensuring uninterrupted functionality for my calculator. However, after several weeks of use, I noticed a slight decrease in battery life compared to the original, requiring more frequent recharging. Overall, while it's a satisfactory replacement with improved capacity, users may need to manage expectations regarding longevity.
