What buyers think
Buyer-review evidence is limited but directionally consistent on the practical side: several reports mention that the battery is a proper fit, the installation process is easy, and the calculator powers back on as expected. A few buyers also describe resolving a functional issue after installing the replacement. Where expectations can diverge is battery longevity, since at least one report indicates a replacement did not last as long as hoped. Overall, the most repeatable themes are compatibility, ease of installation, and getting the device running again, with battery life being the main variable.
What this battery is, and who it’s for
This is a lithium-ion replacement battery meant for select Texas Instruments calculator models: TI-84 Plus CE, TI-Nspire CX II, and TI-Nspire CX CAS II. It’s offered with a specific part number match (3.7L1200SPA or 3.7L12005SPA, and P11P35-11-N01), plus an included tool intended to make the swap easier.
If your calculator is showing signs of weak power, boot problems, or you simply need to restore reliable runtime, this is the kind of replacement many shoppers consider. It’s especially worth looking at when you can confirm your existing battery’s part number and want a direct fit rather than experimenting with generic alternatives.
Key specs you should care about
- Battery type: lithium-ion (rechargeable)
- Voltage: 3.7V
- Capacity: 1500mAh (5.55Wh)

Compatibility: how to avoid the biggest buying mistake
For replacement batteries, the most common failure mode is buying something that does not match your unit’s battery model. To reduce that risk, confirm both the compatible TI model and the battery part number. This battery lists compatibility for TI-84 Plus CE, TI-Nspire CX II, and TI-Nspire CX CAS II, and it references part numbers including 3.7L1200SPA (or 3.7L12005SPA) and P11P35-11-N01.
If you cannot verify your current battery’s exact part number, you may want to pause and double-check before ordering.
Installation experience and real-world expectations
Buyers frequently mention that installation is straightforward and that the replacement gets their calculator back up and running. That said, battery swaps always depend on correct fit and your calculator’s current condition. If the calculator has other underlying issues, a battery replacement can help power-related symptoms, but it may not resolve unrelated hardware or software problems.
Pros and cons (expanded)
Pros
- Designed around specific TI calculator compatibility: reduces the risk of a “wrong battery” experience when you confirm the part number.
- Tool included: can make the swap less hassle than “battery only” listings.
- Clear electrical specs: 3.7V and 1500mAh are listed for shoppers comparing replacements.
- Safety protections: protection against overcharge, overheating, and short-circuit behavior is described.
Cons
- Fit depends on verification: if your part number differs, the battery may not be compatible.
Is it worth it?
This replacement makes the most sense if you need a proper-fit battery for a supported TI model and you can confirm the part number. It’s a practical choice for shoppers who want an easier install (tool included) and a battery built with safety protections and matching voltage/capacity on the listing.
Consider alternatives if you do not know your battery’s exact part number, or if you’re looking for a one-size-fits-all solution. In those cases, the risk of mismatch can outweigh the cost savings versus finding an exact replacement for your calculator.
