Capacity is 2200mAh (24.42Wh), matching the original specification. It connects via the standard LT-series bottom-panel connector and communicates with the Gateway BIOS over the SMBus data line.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLT1000 series fitment:\u003c\/strong\u003e\n    The LT1000 through LT1001J models share the same 11.1V three-cell battery bay, connector pinout, and SMBus handshake. Any unit pulling UM08A73, UM08A72, UM08A74, UM08B73, or UM08B74 will seat this cell without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell against the LT1000 SMBus negotiation cycle. The BMS reported state-of-charge correctly and held the charge threshold without triggering a false overvoltage cutoff during the initial charge sequence.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle conditioning on the LT1000:\u003c\/strong\u003e\n    After installation, run one full discharge until the laptop hibernates on low-battery cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell data and clears the inaccurate health warning that appears on first boot 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\"\u003eWhy the LT1000 shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LT1000's fuel gauge IC retains learned voltage curves from the old cell. After a swap, those curves no longer match the new cell's discharge profile. Under combined CPU and display load, the BIOS sees a voltage reading that maps to near-empty on the old curve and triggers an immediate shutdown — even though actual charge remains. Two to three full discharge-to-hibernate and uninterrupted-charge cycles recalibrate the IC against the new cell chemistry and eliminate the premature cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as poor or 0% on first boot after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Gateway BIOS reads health data from EEPROM fields written by the original factory cell — manufacturer ID, cycle count, and rated Wh. A replacement cell ships with fresh EEPROM values that do not match the old cell's stored history, so the BIOS flags it as unknown or degraded. This is not a fault with the new cell. Complete the full discharge-to-hibernate cycle described above; after two calibration cycles the health indicator updates to reflect the actual cell state. Check battery status in the BIOS at startup — it should read above 95% health after calibration.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410863685722,"sku":"BWCS-ACZG5NK-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410863718490,"sku":"BWCS-ACZG5NK-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410863751258,"sku":"BWCS-ACZG5NK-3","price":37.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ACZG5NK-1.webp?v=1779581401","url":"https:\/\/batteryweb.com\/products\/gateway-lt1000-replacement-battery-111v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
