It replaces the original HB4692J5ECW-31 cell when capacity has dropped or the battery no longer holds a charge. Fits the MateBook D 15-53010TUY and MateBook D 15 AMD models among others in the D 15 lineup.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMateBook D 15 series compatibility:\u003c\/strong\u003e\n    These models share the same battery tray format, connector pinout, and BMS handshake protocol tied to the HB4692J5ECW-31 part number. The voltage rail at 11.46V is consistent across the Intel and AMD variants of the D 15 platform, so one cell fits the full range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on the MateBook D 15. The BMS communicated correctly with the firmware, charge current tapered cleanly at capacity, and no fault codes were logged during cycling.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install learn cycle:\u003c\/strong\u003e\n    After fitting this battery, 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 in system info 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\"\u003eBIOS reporting poor battery health after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MateBook D 15 BIOS reads health data stored in the battery's EEPROM and compares it against the previous cell's cycle history. A brand-new cell has no discharge history, so the BIOS flags it as degraded or unknown until it accumulates calibration data. This is a firmware interpretation issue, not a fault with the replacement battery. One full discharge-to-hibernate followed by a complete uninterrupted charge clears the warning on most MateBook D 15 units.\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 when the fuel gauge IC hasn't yet calibrated against the new cell's actual voltage curve. The IC maps percentage to voltage using data from the old cell, so it misreads the new cell's voltage cliff and triggers a low-battery shutdown before the display figure hits zero. The fix is calibration — discharge the laptop under normal CPU and display load until it hibernates, then charge fully without interruption. After two to three cycles the fuel gauge IC re-maps the curve and the shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409596481626,"sku":"BWCS-HUT150NB-1","price":74.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409596514394,"sku":"BWCS-HUT150NB-2","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409596547162,"sku":"BWCS-HUT150NB-3","price":98.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HUT150NB-1.webp?v=1779580129","url":"https:\/\/batteryweb.com\/products\/huawei-matebook-d-15-2020-replacement-battery-1146v-3600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
