It replaces OEM part numbers including 6-87-M720S-4M4, M720BAT-2, M720BAT-4, and M720SBAT-4, among others. Install it when the original cell no longer holds a charge or when the BIOS flags battery health as degraded.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eM72 series compatibility:\u003c\/strong\u003e\n    The M72, M72X, M72XR, and M72XS all share the same 14.8V battery rail, physical connector, and BMS handshake protocol. That common architecture means one cell fits every variant in this lineup without modification.\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 M72-class hardware. The BMS accepted the new cell cleanly, with no protection trips during charge or under CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBIOS learn cycle after install:\u003c\/strong\u003e\n    After fitting this cell, run the laptop down to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after swapping cells in this platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the M72 BIOS reports poor battery health after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe M72 BIOS reads health data stored in the original cell's EEPROM. When a new cell goes in, that EEPROM data is either absent or mismatched, so the BIOS flags the battery as unknown or degraded even though the cell is fresh. This is a data mismatch, not a hardware fault. Run one full discharge-to-hibernate then a complete uninterrupted charge to 100%, and the BIOS will recalibrate against the new cell's actual parameters.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eM72 shutting down at 20–30% charge remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis symptom points to a voltage cliff in a degraded original cell — under combined CPU and display load, internal resistance climbs and terminal voltage drops below the BMS cutoff threshold before the fuel gauge reaches zero. The OS reads an inaccurate state-of-charge right up until the cell can no longer sustain voltage, then the system cuts immediately. Fitting a fresh cell with lower internal resistance resolves the abrupt shutdown. After installation, confirm the cell holds above 14.0V under load before trusting the fuel gauge readout.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409818845274,"sku":"BWCS-CLM720NB-1","price":65.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409818878042,"sku":"BWCS-CLM720NB-2","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409818910810,"sku":"BWCS-CLM720NB-3","price":85.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLM720NB-1.webp?v=1779581091","url":"https:\/\/batteryweb.com\/products\/clevo-m72-replacement-battery-148v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
