It slots into the existing battery bay and connects through the original multi-pin interface. Voltage, connector pin-out, and BMS communication match the factory specification for this model.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAmilo K7600 compatibility:\u003c\/strong\u003e\n    This battery covers the broad OEM cross-reference pool for the K7600 platform — including 442677000003, 442677000004, BP-8389, BP-8889, and BT.T3007.003. All share the same 11.1V rail, physical form factor, and BMS handshake protocol required by the Amilo K7600 charge controller.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge under CPU-plus-display load. The BMS held voltage above the low-cell cutoff threshold throughout and did not trigger a premature shutdown event. Charge termination occurred cleanly at full cell capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle learn reset on the K7600:\u003c\/strong\u003e\n    After fitting, run the laptop on battery until it hibernates on low-cell cutoff, then charge uninterrupted to 100% without unplugging mid-cycle. This forces the BIOS battery learn cycle to recalibrate against the new cell 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  \u003cp class=\"bpw-desc-p\"\u003eThe Amilo K7600 BIOS reads health data stored in the battery's EEPROM on first connection. A new cell carries factory EEPROM values that do not match the charge history the BIOS expects, so it flags the battery as degraded before a single cycle has run. This is a calibration state, not a fault. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% resets the learn cycle. After two to three full cycles, the BIOS health reading normalises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down abruptly at 20–30% charge shown on the fuel gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet mapped the new cell's discharge curve. The gauge reads voltage against the old cell's profile, so it reports 20–30% remaining at a point where the actual cell voltage is already near cutoff under full CPU and display load. The BMS then trips the protection circuit to prevent deep discharge — the shutdown is correct behaviour, but the displayed percentage is wrong. Complete two full discharge-and-charge cycles without interruption and the fuel gauge IC recalibrates its state-of-charge model against the new cell. After that, shutdown should occur below 5% indicated.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410845237338,"sku":"BWCS-MT8389HB-1","price":86.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410845270106,"sku":"BWCS-MT8389HB-2","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410845302874,"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\/fujitsu-amilo-k7600-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
