TI-84 Plus CE Battery,[2026 New Upgraded] 1600mAh Fits Texas Instruments

Quick take

This replacement battery is built to fit the TI-84 Plus CE and several TI Nspire CX/CX II variants, using the listed part number (3.7L1200SPB, P11P35-11-N01). Buyers commonly choose it to get a calculator working again when the old battery will not hold a charge, including cases where the battery had expanded. The main caveat is making sure your exact model and battery part number match, then charging it fully before evaluating how long it lasts.

Pros and cons

Pros

  • Compatibility focus for TI-84 Plus CE and specific TI Nspire CX/CX II models (including CAS variants), with an explicit part number match.
  • 1600mAh capacity at 3.7V, plus safety protections (microchip protection against over-charging, over-discharging, short-circuiting, and overheating).
  • Buyer reports indicate restored power for calculators that would not turn on due to battery failure.
  • Installation is straightforward, and it is designed for use with the original charger.

Cons

  • Battery longevity beyond the early period is not well proven in the available review evidence, so long-term runtime may vary by usage.
  • If you do not match the correct calculator model and listed part number, fit and performance can be an issue.
  • Some units may arrive with little or no charge, so you may need an initial full charge before judging everyday battery life.

What buyers think

Reviewed productBuy on Amazon

Buyer-review evidence for this battery is primarily about results: it replaces a failing battery and brings the calculator back to life. Several mentions describe calculators that would not power on until the new battery was installed, and others note compatibility and ease of installation. A limited amount of feedback also points to satisfactory day-to-day performance for school or routine use, though longer-term durability evidence is not extensive yet. Overall, the recurring theme is practical recovery, especially when the old battery can no longer hold a charge or has visibly expanded.

Compatibility and specs that matter

This is a replacement battery intended for specific TI models. The listing emphasizes a match for TI-84 Plus CE and TI Nspire CX/CX II (including CAS and CX II CAS variants). It also calls out the part number you should use as a reference, 3.7L1200SPB (P11P35-11-N01). If you are unsure, double-check your calculator model and any existing battery markings before ordering.

Key technical details include:

  • Battery capacity: 1600mAh
  • Voltage output: 3.7V
  • Watt-hour rating: 5.92Wh
  • Cell type: NiMH
  • Safety protection microchip: over-charging, over-discharging, short-circuit, and overheating protection

Installation and getting accurate runtime

Installation is described as user-friendly, and the battery is intended to be charged with the original charger. One practical note buyers should expect: some replacements may ship with little or no power, so it is smart to fully charge it before judging battery life. If you install it and the calculator behaves unexpectedly right away, a full initial charge can prevent a misleading first impression.

Who it’s best for

  • Students or professionals with a TI-84 Plus CE who need a replacement battery and want clear model and part-number alignment.
  • TI Nspire CX and CX II owners (including CAS models) looking for a compatible internal battery swap.
  • Buyers whose calculators are not turning on or are losing charge quickly due to a failing battery.

Who should avoid it

  • Anyone who cannot confirm their device model and the listed battery part number compatibility.
  • Shoppers who need thoroughly proven long-term endurance from robust multi-year review patterns, since the available feedback is mostly early-stage replacement success.

Is it worth it?

If your TI calculator is acting like the battery is failing, this is a sensible path because it is designed for a specific set of models and includes safety protections. The most important value factor is fit. When the part number and calculator model match, buyers report the calculator returns to normal operation quickly after installation. If you are trying to decide purely on “battery life improvement” expectations, remember that real-world endurance can depend on how your device is used, and long-term confirmation in the review evidence is limited.
