It replaces OEM part numbers 7004, 7005, 7006, 7170, 8170, 8175, 442671200001, 442671200002, and 442671200005. If your original cell is swelling, no longer holding a charge, or the laptop won't run unplugged, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMaxForce 8175 battery platform:\u003c\/strong\u003e\n    These part numbers all share the same physical connector, cell configuration, and BMS handshake required by the MaxForce 8175 mainboard. The 11.1V three-cell arrangement matches the voltage rail the system expects — substituting a different voltage grouping will trigger an immediate BMS reject.\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 a MaxForce 8175 unit. The BMS accepted the cell without error, negotiated charge current correctly, and cut off at the expected low-voltage threshold without dropping into an unrecoverable deep-drain state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle reset after install:\u003c\/strong\u003e\n    After fitting this battery, run the laptop down until it hibernates on its own — do not force-shutdown — then charge uninterrupted to 100%. This single discharge-to-hibernate cycle resets the BIOS battery learn cycle and clears the spurious \"poor health\" warning that appears after any 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 poor battery health immediately after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe MaxForce 8175 BIOS reads health data stored in the battery's EEPROM and compares it against the wear history of the old cell. When a new cell arrives, that EEPROM data doesn't match the system's learned baseline, so the BIOS flags it as degraded before a single cycle has run. This is a firmware artefact — not a fault with the new battery. One complete discharge-to-hibernate followed by a full uninterrupted charge gives the BIOS enough data to recalibrate. After that cycle, the health warning clears and the reported percentage tracks accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC was calibrated against the old, degraded cell — it mapped \"30% remaining\" to a voltage that the old cell hit near empty. The new cell hits that same voltage much earlier in its actual discharge curve, so the system shuts down while the gauge still shows charge remaining. It's a calibration mismatch, not a fault with the replacement. Run two full discharge-to-hibernate cycles and charge each time to 100% without interruption. After the second cycle the fuel gauge IC re-anchors its curve to the new cell and the readings stabilise — confirm by checking that shutdown now occurs below 5% or at the hibernate threshold you have set in power options.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410830721114,"sku":"BWCS-MT8100NB-1","price":75.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410830753882,"sku":"BWCS-MT8100NB-2","price":88.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410830786650,"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\/dtk-maxforce-8175-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
