WUHAO TI-84 Plus CE Battery Replacement 1500mAh for Texas Instruments
Quick take
This 3.7V, 1500mAh Li-ion replacement battery is made for select Texas Instruments models, including TI-84 CE, TI-84 Plus CE, and TI-Nspire CX II (and Color). It’s a practical choice when your calculator isn’t holding power and you want to restore performance without replacing the whole device. The main buying caveat is fit, you must match your calculator model and the specific battery part number (3.7L12005SPA / P11P35-11-N01).
Pros and cons
Pros
- Designed for compatibility with TI-84 CE, TI-84 Plus CE, and TI-Nspire CX II/Color models, using part numbers 3.7L12005SPA / P11P35-11-N01.
- 1500mAh, 3.7V battery capacity intended to replace a failing internal battery.
- Buyers describe the install as manageable and the battery as a solid fix for non-booting or boot-loop behavior.
- Includes an installation tool (a screwdriver) mentioned by reviewers.
- Built with protection features intended to guard against over-charging, over-discharging, over-heating, and short-circuiting.
Cons
- Compatibility depends on your exact calculator model and battery part number, so double-check before purchasing.
- Battery life feedback is mixed in detail, so expectations for runtime can vary by use.
- As with any internal battery replacement, opening the calculator is required, which is not ideal for everyone.
What buyers think
Buyer-review evidence is broadly positive, with multiple reviewers describing the replacement as restoring normal operation and solving real-world battery-related issues such as failing to boot or boot screen loops. Review themes also consistently mention easy installation, a good fit once installed, and value versus buying a whole new calculator. At the same time, the review evidence does not provide detailed, standardized battery-life measurements, so runtime expectations should be treated as use-dependent rather than guaranteed.
What this battery replacement is for
This is a replacement internal battery for specific Texas Instruments handheld models. It targets the common situation where a TI calculator becomes unreliable due to an aging or failing battery, including symptoms like wonky startup behavior or a calculator that effectively stops holding power.
Compatibility you should verify first
To avoid ordering the wrong part, confirm your calculator’s battery match against these supported models and battery identifiers:
- Compatible models include: TI-84 CE, TI-84 Plus CE, TI-Nspire CX II, TI-Nspire CX II Color, and TI-Nspire CX II CAS.
- Battery part numbers listed for fit: 3.7L12005SPA and P11P35-11-N01.
- Battery specs listed: 3.7V, 1500mAh Li-ion.
If your model is close but not listed, or if your existing battery number doesn’t match, you should not assume compatibility.
Key features that matter in daily use
Capacity and voltage for a like-for-like replacement
The listed 3.7V output and 1500mAh capacity are meant to align with the original battery’s electrical requirements so your calculator can run normally after the swap.
Protection features aimed at safer operation
Safety and reliability matter most for internal batteries. This replacement includes protection intended to help guard against over-charging, over-discharging, over-heating, and short-circuiting.
Physical fit and install support
Reviewers repeatedly describe the install as straightforward, and one snippet specifically mentions a screwdriver included with the kit. Still, internal replacement work always requires careful handling, especially if you’re not used to opening electronics.
Pros and cons: is it worth it?
Buy it if
- You have a TI-84 CE, TI-84 Plus CE, or TI-Nspire CX II/Color model and your symptoms point to battery failure.
- You want to revive a working calculator rather than replace the entire device.
- You’re comfortable doing a battery swap and you can confirm the correct battery part numbers (3.7L12005SPA / P11P35-11-N01).
Consider a different approach if
- You cannot verify compatibility with your exact calculator model and existing battery number.
- You prefer a plug-in or external battery solution, since this requires opening the calculator.
- You need precise, documented runtime performance, because user feedback does not include standardized battery-life testing.
How to choose the right internal battery (quick checklist)
- Match your calculator model to the supported list (TI-84 CE, TI-84 Plus CE, TI-Nspire CX II/Color, TI-Nspire CX II CAS).
- Verify the battery part number printed on the original (3.7L12005SPA or P11P35-11-N01).
- Confirm the listed electrical specs (3.7V, 1500mAh) align with what your device uses.
- Plan for careful installation, since this is an internal component replacement.
Verdict
The WUHAO TI-84 Plus CE battery replacement is a sensible option for shoppers who need a specific 3.7V 1500mAh replacement for compatible TI-84 CE/TI-84 Plus CE and TI-Nspire CX II/Color/CAS models. The strongest evidence is practical, reviewers describe it as an effective fix for battery-related startup problems and as an install that many people can handle. If you’re unsure about fit, pause and confirm the exact battery part number before ordering.
