Found out it’s a common problem where the original battery stops being able to be recharged. Was an easy switch and 6 months later, the calculator still works and is able to hold a charge. Worth it! ### ⭐⭐⭐⭐⭐ Exactly as advertised *by D***E on 21 August 2026* Easy to replace. Saved me buying a new calculator. ### ⭐⭐⭐⭐⭐ Replacement battery for TI-84 Plus CE *by S***. on 14 May 2025* Replaced the battery on my son’s TI-84 Plus CE. I’ve read online that the OEM battery lasts for a few years before it doesn’t work anymore. For my son’s TI, the battery wouldn’t charge. When plugged in, the screen kept trying to turn on then turn off. After reading online reviews I found this battery replacement and decided to give it a try. It comes with a mini-screwdriver. I replaced the battery and the TI-84 came back to life. My son QA’d it and everything seems to be function like it did before. I’ll update this review if anything goes awry but so far I’m very happy to spend $12 to replace the battery instead of having to replace the whole graphing calculator. ## Frequently Bought Together - oliadeo TI 84 Plus CE Battery - Replacement for Texas Instruments TI-84 Plus CE Battery - Part No 3.7L1200SPA, P11P35-11-N01 3.7V 1500mAh - YEHUIM Charger Cable Compatible with Texas Instruments TI-84 Plus CE, TI 84 Plus C Silver Edition, TI Nspire CX/TI Nspire CX CAS Graphing Calculator Charging Cord --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/736780875-ti-84-plus-ce-battery-replacement-for-texas-instruments-ti](https://www.desertcart.be/products/736780875-ti-84-plus-ce-battery-replacement-for-texas-instruments-ti) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-17*
