It replaces the original cell when capacity has degraded past usable levels. The connector, voltage rail, and physical dimensions match the factory spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSabrePro 15 series fit:\u003c\/strong\u003e\n    The G, base, and W8 variants share the same battery bay dimensions, 11.4V three-cell configuration, and BMS connector pinout — that's why one cell covers all three models.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge and discharge cycles on the bench and confirmed the BMS handshake completes correctly, charge current ramps as expected, and the protection circuit trips at the correct low-voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install recalibration on the SabrePro:\u003c\/strong\u003e\n    After fitting this cell, let the laptop discharge fully until it hibernates, then charge uninterrupted to 100%. 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 battery health as poor immediately after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SabrePro reads EEPROM data embedded in the original cell and compares it against the current charge state. A new cell has no charge history, so the BIOS flags it as degraded on first boot. This is a firmware behaviour, not a fault with the replacement cell. Run one full discharge-to-hibernate cycle followed by a full uninterrupted charge — the BIOS learn cycle will update and the health flag will clear.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% remaining after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC in the SabrePro calibrates its state-of-charge estimate against the old cell's charge curve. After a swap, it does not yet know where the new cell's voltage cliff sits under full CPU and display load. As the battery approaches that cliff, voltage drops faster than the gauge predicts and the system shuts off to protect the cell. Two or three full discharge-and-charge cycles re-teach the gauge — after calibration, the reported percentage will track accurately down to the cutoff near 3.0V per cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409626497114,"sku":"BWCS-THR911NB-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409626529882,"sku":"BWCS-THR911NB-2","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409626562650,"sku":"BWCS-THR911NB-3","price":97.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-THR911NB-1.webp?v=1779580312","url":"https:\/\/batteryweb.com\/products\/gigabyte-sabrepro-15-g-replacement-battery-114v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
