It replaces a wide range of OEM part numbers including 442677000001, BP-8389, BP-8089, and BT.T3007.003, among others. If the original cell has degraded or no longer holds charge, this unit restores full battery operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-reference coverage:\u003c\/strong\u003e\n    Gericom used multiple OEM part numbers across notebook revisions — same voltage rail, same connector, same BMS handshake protocol. This battery covers that full cross-reference pool, including BP-8889, BP-LYN 4000, 442682800002, and 3CGR18650A3-MSL variants.\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 cycles on Gericom notebook hardware. The BMS negotiated correctly with the system, accepted a full charge to 11.1V nominal, and held stable voltage under sustained CPU and display load without triggering a protection cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge to hibernate-cutoff, 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 Gericom systems.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy BIOS reports poor battery health immediately after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eGericom notebooks store battery health data in the old cell's EEPROM. When a new cell is installed, the BIOS reads no matching EEPROM history and flags the battery as degraded or unknown. This is a data mismatch, not a fault with the replacement cell. Running a full discharge-to-hibernate followed by a complete uninterrupted charge forces the BIOS to write new learn-cycle data and clear the warning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown 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 discharge curve. The gauge inherited calibration data from the old, degraded cell and predicts voltage collapse too early. Under combined CPU and display load, the laptop interprets a normal mid-range voltage as critically low and shuts down. Run two to three full discharge-and-charge cycles — the fuel gauge IC will recalibrate and the cutoff point will shift back toward the correct low-voltage threshold near 9V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410845958234,"sku":"BWCS-MT8389HB-1","price":86.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410845991002,"sku":"BWCS-MT8389HB-2","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410846023770,"sku":"BWCS-MT8389HB-3","price":112.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MT8389HB-1.webp?v=1779581320","url":"https:\/\/batteryweb.com\/products\/gericom-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
