It fits the HBL-W29, MagicBook Pro 2020, and HLY-W19RP variants that share the same connector and BMS handshake protocol. Capacity figures come directly from product data — not estimated from third-party sources.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMateBook D 16 platform fit:\u003c\/strong\u003e\n    The MateBook D 16, HBL-W29, and MagicBook Pro 2020 all run the same 15.28V four-cell Li-Polymer architecture with an identical connector pinout and BMS communication line. Swapping a cell from any of these models into another does not require firmware changes — the voltage rail and protection circuit match.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a MateBook D 16 unit and confirmed the BMS handshake completed without fault codes. The protection circuit engaged correctly at low-voltage cutoff, and charge termination fired at the expected voltage ceiling during full-charge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration for MateBook D 16:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. The MateBook D 16's BIOS battery learn cycle resets on that sequence — skipping it causes the fuel gauge IC to misread state-of-charge and triggers a false \"battery poor\" health warning in the system dashboard.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the MateBook D 16 shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still reading state-of-charge against the impedance profile of the old, degraded cell. Under combined CPU and display load, the new cell's actual voltage is fine — but the IC hits a programmed threshold it mapped to the worn cell and triggers an early shutdown. The BIOS hasn't yet learned the new cell's voltage curve. One full discharge-to-hibernate followed by an uninterrupted charge to 100% rewrites the learn cycle. After two or three complete cycles, the shutdown behaviour clears and the gauge tracks correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS showing wrong Wh rating after fitting the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Wh value the BIOS displays is pulled from EEPROM data embedded in the battery's protection circuit board — not measured live from the cell. If the EEPROM stores the rated chemistry value and the actual cell has a slightly different nominal capacity, the two figures diverge. This is a data mismatch, not a defective unit. The cell itself operates at the correct 15.28V and 55.01Wh. Confirm actual capacity by running a full discharge cycle and checking what the OS energy report logs as full-charge capacity against the 55.01Wh spec.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409585209434,"sku":"BWCS-HUW290SL-1","price":84.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409585242202,"sku":"BWCS-HUW290SL-2","price":99.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409585274970,"sku":"BWCS-HUW290SL-3","price":110.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HUW290SL-1.webp?v=1779580129","url":"https:\/\/batteryweb.com\/products\/huawei-matebook-d-16-replacement-battery-1528v-3600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
