It replaces OEM part numbers PA3000UR, PA3001U-1BRM, PA2505, PA3000U-1BRS, and PA3001. Capacity is 32.4Wh — matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePortege 7000 series compatibility:\u003c\/strong\u003e\n    The Portege 7000, 7020CT, 7140CT, and 7220CT all share the same 10.8V three-cell battery rail, connector pinout, and BMS handshake protocol. One cell fits all these models 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 full charge and discharge on a Portege 7140CT. The BMS communicated correctly with the system board, reported state-of-charge accurately after two calibration cycles, and held voltage above the low-battery cutoff threshold throughout discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Portege platform:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge until the laptop hibernates on its own, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears immediately after every 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 poor battery health after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Portege 7000 series stores battery health data in EEPROM on the system board, not on the cell itself. When a new cell goes in, the BIOS compares current readings against the old cell's stored history and flags the battery as degraded or unknown. This is not a fault with the replacement cell — it is a stale data mismatch. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% overwrites the old EEPROM values and clears the warning within one to two cycles.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% remaining on the gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The gauge reads 20–30% but the cell has already dropped below the minimum voltage the CPU and display load require — typically around 9.5V under full draw on this platform. The system shuts down before the OS can respond. Run two full calibration cycles — full discharge to hibernate, full charge to 100% each time — and the fuel gauge IC will map the new cell's curve correctly, moving the shutdown point back to the correct threshold near 0%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410875252826,"sku":"BWCS-TO7000-1","price":62.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410875285594,"sku":"BWCS-TO7000-2","price":73.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410875318362,"sku":"BWCS-TO7000-3","price":81.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TO7000-big.webp?v=1779581546","url":"https:\/\/batteryweb.com\/products\/toshiba-portege-7140ct-replacement-battery-108v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
