It replaces OEM part numbers including 2C.20770.001, SQU-701, and 916C5820F, among others. Install it when the original pack no longer powers the laptop away from mains.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMH-series platform fit:\u003c\/strong\u003e\n    The MH35, MH36, MH45, and MH85 share the same 11.1V three-cell rail, connector pinout, and BMS handshake protocol — one pack covers all of them without any modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on the EasyNote platform. The BMS communicated correctly with the system, and the charge controller accepted full charge without tripping a fault state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the EasyNote:\u003c\/strong\u003e\n    After installing, 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.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the EasyNote BIOS flags a new battery as poor health immediately after swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe EasyNote BIOS reads health data stored in the original pack's EEPROM. When a new cell goes in, that EEPROM data is gone — the BIOS has no reference point and defaults to a \"poor\" or \"unknown\" status. This is not a fault with the replacement pack. Running one full discharge-to-hibernate then a complete uninterrupted charge gives the BIOS enough data to rewrite its internal battery profile. After one or two cycles, the health status corrects itself.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on the indicator\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 is still using parameters from the degraded original pack, so it misreads remaining capacity and triggers a low-power shutdown too early. It is not a fault in the replacement battery. Run two full discharge-to-hibernate cycles followed by uninterrupted charges to 100% — after that, the fuel gauge re-anchors its curve and the shutdown behaviour stops. Confirm calibration is complete when the system reaches hibernate at or below 5% reported charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410814828634,"sku":"BWCS-BUS42NB-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410814861402,"sku":"BWCS-BUS42NB-2","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410814894170,"sku":"BWCS-BUS42NB-3","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BUS42NB-1.webp?v=1779581181","url":"https:\/\/batteryweb.com\/products\/packard-bell-easynote-mh35-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
