It replaces OEM part numbers CGR-B\/350CW, 3UR18650H-QC174, and BT.00603.018. Capacity is 2200mAh (24.42Wh) — use this figure, not inflated third-party specs circulating online.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTravelMate 3030 and Ferrari 1000 platform fit:\u003c\/strong\u003e\n    These models share a common 11.1V three-cell battery rail, the same physical connector, and compatible BMS handshake logic — which is why one cell covers variants including the Ferrari 1005WLMi, 1003WTMi, and 1000-5612.\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 TravelMate 3030 chassis. The BMS accepted the charge handshake on first connection, hit charge cutoff at 12.6V, and the BIOS registered the cell without error codes after a full calibration cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the TravelMate 3030:\u003c\/strong\u003e\n    After fitting, run one full discharge down to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that typically appears after a cell swap on this platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as poor immediately after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe TravelMate 3030 BIOS reads health data stored in the old cell's EEPROM. When a new cell goes in, that EEPROM data no longer matches the actual cell state, so the BIOS flags it as degraded or unknown — even though the cell is new. This is not a fault with the replacement battery. Run the full discharge-to-hibernate then uninterrupted charge cycle described above. After two to three full cycles, the fuel gauge IC recalibrates against the new cell and the health warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below the BMS cutoff threshold under combined CPU and display load — even though the OS gauge still reads 20–30%. It is a fuel gauge calibration problem, not a defective cell. The gauge IC is still mapping charge levels against the old cell's discharge curve. Run two full discharge-to-hibernate cycles followed by uninterrupted charges to 100%. After calibration, the OS gauge and actual cutoff voltage should align — confirm by checking that shutdown no longer occurs above 10% shown.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410854772826,"sku":"BWCS-AC100NB-1","price":61.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410854805594,"sku":"BWCS-AC100NB-2","price":71.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410854838362,"sku":"BWCS-AC100NB-3","price":79.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AC100NB-big.webp?v=1779581356","url":"https:\/\/batteryweb.com\/products\/acer-travelmate-3030-replacement-battery-111v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
