It also fits the TI-84 Plus C Silver Edition and related N2\/AC\/2L1\/A variants. Matches OEM part numbers 3.7L1060SP, 3.7L1230SP, 3.7L1200SP, and 541383800002 series cells.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTI-Nspire CX and CX CAS compatibility:\u003c\/strong\u003e\n    Both the standard CX and the CAS variant share the same battery bay dimensions, connector pinout, and BMS communication protocol — this cell works in either without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell in a TI-Nspire CX and confirmed the BMS accepted the charge curve without triggering a fault state. Voltage held steady across charge and discharge without dropout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRAM data protection before swap:\u003c\/strong\u003e\n    Export or photograph all stored programs, lists, and variables before removing the battery. The TI-Nspire CX stores user data in RAM powered directly by the main cell — pulling the battery clears everything in that memory instantly.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCalculator clock resetting after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe TI-Nspire CX uses the main Li-ion cell to maintain its real-time clock — there is no dedicated backup coin cell on this board. When the main battery is removed, the RTC loses power and resets to a default timestamp. After fitting the new cell, go to Settings → General → Date and Time and set the correct values manually. This does not affect math or CAS functions, but OS-level file timestamps will be wrong until corrected.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNew battery shows low charge indicator immediately after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eReplacement cells ship at storage voltage — typically around 3.6V — not at a full 4.2V charge. The CX battery indicator reads this as a low or partially depleted state, which is normal. Connect the calculator to the TI wall adapter or USB port and allow a full charge cycle to complete before drawing conclusions about cell capacity. Once the cell reaches 4.2V and the indicator shows full, the reading stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333541494874,"sku":"BWCS-TEX060XL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333541527642,"sku":"BWCS-TEX060XL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333541560410,"sku":"BWCS-TEX060XL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TEX060XL-1.webp?v=1778212957","url":"https:\/\/batteryweb.com\/products\/texas-instruments-ti-nspire-cx-replacement-battery-37v-1300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
