It replaces OEM part numbers PA2510, PA2510U, PA2510UR, and PA3010U-1BAR. The battery slots into the Tecra 8000 bay and connects to the system board via the original multi-pin connector.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTecra 8000 platform fit:\u003c\/strong\u003e\n    All four OEM part numbers listed above draw from the same 10.8V three-cell series configuration. The connector pinout and BMS handshake protocol are identical across that part range, so one replacement cell covers the full group.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge on a Tecra 8000 unit. The BMS accepted the charge cycle without tripping, voltage held steady across load transitions, and the system board completed its handshake correctly on first recognition.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration for the Tecra 8000:\u003c\/strong\u003e\n    After fitting, run the battery down fully until the laptop hibernates, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears 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 immediately after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Tecra 8000 BIOS reads health data stored in the battery's EEPROM. When a new cell arrives, that EEPROM carries factory default values that don't match the laptop's charge history, so the BIOS flags it as degraded. This is a data mismatch, not a faulty battery. Running one complete discharge-to-hibernate followed by a full uninterrupted charge gives the BIOS enough cycle data to update its health register correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTecra 8000 shutting down unexpectedly at 20–30% charge shown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still calibrated to the old, degraded cell's discharge curve. The new cell hits a voltage cliff under combined CPU and display load before the gauge reaches 0%, triggering an abrupt shutdown rather than a graceful hibernate. The fix is the same calibration cycle — drain fully to hibernate cutoff, then charge straight to 100%. After two full cycles the fuel gauge IC re-maps its curve against the new cell and the shutdowns stop. Confirm the cell has reached at least 12.5V on the charger before disconnecting during the first calibration charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410875351130,"sku":"BWCS-TO8000-1","price":56.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410875383898,"sku":"BWCS-TO8000-2","price":65.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410875416666,"sku":"BWCS-TO8000-3","price":73.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TO8000-big.webp?v=1779581546","url":"https:\/\/batteryweb.com\/products\/toshiba-tecra-8000-replacement-battery-108v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
