It covers OEM part numbers AS11A3E, AS11A5E, 3ICR19\/66-2, and 3INR18\/65-2. Fit the battery when the original no longer holds a charge or the system reports critically degraded health.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTimelineX 3830T series fit:\u003c\/strong\u003e\n    All 3830T variants share the same 11.1V three-cell configuration, connector pinout, and BMS handshake protocol — that is why one part number covers the full model range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a 3830T unit. The BMS negotiated correctly with the system board, the charge IC accepted the full 4400mAh capacity, and no protection trips fired during load testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the 3830T:\u003c\/strong\u003e\n    After fitting, run the laptop on battery until it reaches hibernate cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell and clears the inaccurate health warning that appears after every cell swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the 3830T BIOS flags a new battery as poor health immediately after fitting\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 3830T stores charge history and wear data in EEPROM on the battery's BMS board. When the old cell is removed, that accumulated data is gone. The BIOS compares the new cell's EEPROM baseline against its stored expectations and scores the mismatch as degraded health. This is not a fault with the replacement cell — it is a calibration state. One full discharge-to-hibernate followed by an uninterrupted charge to 100% rewrites the learn cycle and resolves the warning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003e3830T shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when an aged cell can no longer hold voltage under the combined load of the CPU, display backlight, and storage at the same time. As the cell depletes past roughly 20%, internal resistance rises sharply, voltage sags below the BMS cutoff threshold, and the system drops power instantly rather than reaching the OS shutdown point. A new cell with healthy internal resistance will sustain voltage through that load range. After fitting the replacement, run the calibration cycle described above so the fuel gauge IC maps the actual discharge curve — without calibration, the gauge inherits the old cell's curve and the early-shutdown behaviour may persist until the IC relearns.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409783619674,"sku":"BWCS-AC3830NB-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409783652442,"sku":"BWCS-AC3830NB-2","price":85.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409783685210,"sku":"BWCS-AC3830NB-3","price":94.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AC3830NB-1.webp?v=1779580817","url":"https:\/\/batteryweb.com\/products\/acer-aspire-timelinex-3830t-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
