It replaces OEM part numbers 96BTA016H, 96BTA015H, and DYNC01. If your Surface Pro 8 no longer holds a charge or won't run unplugged, this is the direct cell replacement.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSurface Pro 8 (1982 \/ 1983) fit:\u003c\/strong\u003e\n    Both model variants share the same battery bay dimensions, connector pinout, and BMS communication protocol — this cell fits either board revision without modification.\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 Surface Pro 8 unit. The BMS handshake completed correctly, charge IC accepted the cell without fault flags, and voltage held steady under display and WiFi combined load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. The Surface fuel gauge IC is calibrated against the old cell — this single cycle resets it against the new capacity and clears the inaccurate percentage readout that appears after a swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSurface Pro 8 shutting down at 15–25% remaining after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC still holds calibration data from the original cell. When voltage drops under combined display and WiFi load, the IC reads a steeper voltage cliff than the new cell actually has, and Windows triggers shutdown early. The fix is one complete discharge-to-shutoff cycle followed by an uninterrupted charge to 100%. After that cycle, the IC maps the new cell's voltage curve and the early shutdown stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable on Surface Pro 8 after swapping the battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Surface Pro 8 uses USB-PD negotiation to determine charge rate. On a fresh cell, the charge IC may not approve elevated current until it has completed one accepted charge cycle at standard rate. Plug into the original Surface charger — not a third-party USB-C adapter — and let it complete a full charge without interruption. After that first accepted cycle, USB-PD negotiation runs normally and fast charge becomes available again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425824342106,"sku":"BWCS-MCR198SL-1","price":78.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425824374874,"sku":"BWCS-MCR198SL-2","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425824407642,"sku":"BWCS-MCR198SL-3","price":103.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MCR198SL-1.webp?v=1779929837","url":"https:\/\/batteryweb.com\/products\/microsoft-surface-pro-8-replacement-battery-1138v-4400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
