It replaces OEM part numbers 7004, 7005, 7006, 7170, 8170, 8175, 442671200001, 442671200002, and 442671200005. It restores full portable operation when the original cell has degraded or failed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNote 8170 compatibility:\u003c\/strong\u003e\n    These OEM part numbers all map to the same 11.1V cell configuration and connector pinout used across the Note 8170 platform. The BMS handshake protocol and EEPROM data structure are consistent across all listed part numbers, so the replacement negotiates correctly with the laptop's 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 on Note 8170 hardware. The BMS communicated without fault codes, charge termination occurred correctly at full voltage, and the fuel gauge IC accepted the new cell data without triggering a persistent error state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation calibration on the Note 8170:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge to the laptop's hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning the firmware logs every time a new cell is installed.\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 the new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Note 8170 BIOS reads health data from the battery's EEPROM, which stores cycle count and capacity history from the previous cell. When a new cell arrives, that EEPROM data doesn't match the fresh chemistry, so the firmware flags it as degraded. This is a firmware interpretation issue, not a fault with the replacement cell. Run the full discharge-to-hibernate then uninterrupted charge cycle described above. After one complete learn cycle, the BIOS recalibrates and the health warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down unexpectedly while the OS still shows 20–25% remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't yet mapped the voltage curve of the new cell. Under combined CPU and display load, voltage drops faster than the uncalibrated gauge predicts, and the laptop hits the hardware cutoff before the displayed percentage reaches zero. It's not a defective cell — it's a calibration gap. Complete two full discharge-to-hibernate and uninterrupted recharge cycles. After that, the fuel gauge tracks the actual voltage cliff correctly and the premature shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410830917722,"sku":"BWCS-MT8100NB-1","price":75.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410830950490,"sku":"BWCS-MT8100NB-2","price":88.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410830983258,"sku":"BWCS-MT8100NB-3","price":98.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MT8100NB-big.webp?v=1779581286","url":"https:\/\/batteryweb.com\/products\/accel-note-8170-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
