It replaces original cells that no longer hold charge due to normal cycle degradation. Voltage and connector match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eT6800 and T6300 series fit:\u003c\/strong\u003e\n    These models share the same 11.1V three-cell voltage rail, identical connector pinout, and BMS communication protocol — which is why one cell covers the full range. The battery management system handshake is consistent across the platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on the T6810 platform and confirmed the BMS accepted the new cell without fault codes, charged to full capacity, and discharged cleanly through a full load cycle without premature cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle on the T6810:\u003c\/strong\u003e\n    After fitting this battery, run the laptop on battery power until it hibernates at low charge, then charge it 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\"\u003eBIOS reporting battery health as poor after replacement on the T6810\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe T6810 BIOS reads health data from EEPROM registers on the battery's fuel gauge IC. When a new cell is installed, those registers still carry stale data calibrated to the old cell's charge history. The BIOS interprets this mismatch as degraded capacity and flags poor health immediately. Running one complete discharge-to-hibernate followed by a full uninterrupted charge resets the learn cycle. After two to three full cycles, the BIOS health indicator should read normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eT6810 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated to the new cell's actual voltage curve. The OS fuel gauge reads a percentage based on voltage thresholds set for the old cell, so it reports 25% while the new cell is actually near its discharge floor. Under full CPU plus display load, the voltage drops fast at that point and the system shuts down without warning. Run two or three full discharge-recharge cycles to let the fuel gauge IC re-map the curve against the new cell — shutdowns should stop once the calibration settles at the correct cutoff voltage of approximately 9.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43411617742938,"sku":"BWCS-GWP170NB-1","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43411617775706,"sku":"BWCS-GWP170NB-2","price":82.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43411617808474,"sku":"BWCS-GWP170NB-3","price":91.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GWP170NB-1.webp?v=1779581142","url":"https:\/\/batteryweb.com\/products\/gateway-t6810-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
