TI-84 Plus CE Battery Replacement (1600mAh)
Quick take
This TI-84 Plus CE replacement battery is a rechargeable lithium-ion pack rated at 1600mAh (3.7V) and designed for specific TI-84 Plus CE and TI-Nspire CX II model compatibility. Buyers who chose it for a failing or “dead” calculator report it restoring normal function with a proper fit, but you should plan to fully charge it first because it ships only partially pre-charged.
Pros and cons
Pros
- Targets the right devices: compatible with TI-84 Plus CE and selected TI-Nspire CX II / CX II CAS models, with a listed part number to match.
- 1600mAh rechargeable lithium-ion capacity: designed to support longer study and work sessions between recharges.
- Safety-focused design: includes protection circuitry to help prevent overcharging, short circuits, overheating, and overvoltage.
- Practical for repairs: includes a repair tool (per the item details shown).
Cons
- Compatibility is strict: you need to verify the battery model/part number inside your calculator before ordering.
- Not fully charged on arrival: ships at 15% to 30% pre-charge, so expect a full charge before dependable runtime.
What buyers think
Buyer-review evidence in this listing is limited to a small set of reports, but the recurring themes are clear: the battery tends to fit properly, and it can bring an otherwise unusable TI-84 Plus CE back to working order when the original battery has failed. Reviews also describe straightforward replacement behavior (“works as expected”) rather than issues with installation or device recognition. Because the sample size is relatively small, it is difficult to draw strong conclusions about long-term runtime performance beyond general expectations for a higher-capacity replacement.
Who this battery is for
This is a good match if you want a replacement battery to restore power to a compatible TI-84 Plus CE or specified TI-Nspire CX II / CX II CAS models, and you are comfortable verifying the correct internal battery model/part number before purchase. It is also a practical choice for students and professionals who rely on calculator uptime, especially when you prefer repairing your existing device instead of replacing the whole calculator.

Pros and cons in real buying terms
Why buyers choose it
Most shoppers looking at replacement batteries are trying to fix a “dead” or unreliable calculator without switching models. This battery is positioned around proper-fit compatibility for specific TI models and includes protection circuitry intended to improve charging safety. The included repair tool can reduce friction if you are doing the swap yourself.
Where shoppers need to be careful
The biggest decision factor is compatibility. If your calculator’s internal battery model or part number does not match what is listed, the replacement may not fit or work as intended. Also, because the battery arrives only partially charged, your first runtime expectations should start after a full initial charge.
Battery performance expectations
The capacity rating (1600mAh) and the deep-cycle estimate (up to 1200+ cycles) suggest the battery is meant for longer-term use, not just a short stopgap. However, runtime in real life can vary based on usage patterns (screen behavior, how frequently you run calculations, and ambient conditions). If you mainly need reliable power for everyday coursework, this kind of higher-capacity replacement generally aligns with that goal, as long as the installation is done correctly and the device is the supported model.
Price and availability
This item is listed as in stock in the product details provided, and it sits in a low-cost range compared with replacing a whole calculator. If you want the most accurate cost snapshot, check the current listing price here: Buy on Amazon.
Verdict
Choose this TI-84 Plus CE replacement battery if you have a compatible TI-84 Plus CE (and/or the specified TI-Nspire CX II models) and you want a safety-protection-equipped, rechargeable 1600mAh replacement that buyers report fitting well and restoring function. Pass if you are not willing to confirm the internal battery model/part number first, or if you need a battery that arrives fully charged for immediate use.
