It matches OEM part numbers MS011301-PLP22T02, G3HTA005H, G3HTA009H, and 1577-9700. Capacity figure is taken directly from product data — 41.8Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSurface 3 and Surface Pro 3 compatibility:\u003c\/strong\u003e\n    Both devices share a common 7.6V cell architecture, the same flat Li-Polymer form factor, and an identical BMS handshake protocol over the internal bus — which is why one part number covers both platforms.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge cycle on a Surface 3 unit. The BMS accepted the new cell without error flags, charge IC negotiated normally, and the tablet reached full charge without thermal events or charge-state faults.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge reset after installation:\u003c\/strong\u003e\n    After fitting this battery, run the tablet down to automatic shutoff — do not force it off — then charge uninterrupted to 100% without using the device. This gives the fuel gauge IC a full reference window against the new cell and clears the inaccurate percentage readings that almost always appear 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\"\u003eWhy the Surface 3 shuts down at 15–25% battery remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Surface 3 runs a combined display and WiFi load that pulls current sharply. When the cell is degraded, voltage sags under this combined draw faster than the fuel gauge tracks. The OS sees a valid percentage, but actual cell voltage drops below the BMS cutoff threshold — and the tablet shuts off. A replacement cell with full capacity raises the voltage floor under load, so the BMS no longer trips before the gauge reaches zero.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging not resuming after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter fitting a new cell, the Surface Connect charge IC may default to trickle charge for the first session — this is the controller treating the new cell as unknown until one full accepted cycle completes. USB-PD negotiation on the Surface 3 also re-initialises after a power interrupt, which a battery swap triggers. Charge the tablet from 0% to 100% in one uninterrupted session using the original Microsoft charger. After that cycle completes, fast charge behaviour returns to normal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426007187546,"sku":"BWCS-MIS016SL-1","price":68.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426007220314,"sku":"BWCS-MIS016SL-2","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426007253082,"sku":"BWCS-MIS016SL-3","price":87.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MIS016SL-1.webp?v=1779930219","url":"https:\/\/batteryweb.com\/products\/microsoft-surface-3-replacement-battery-76v-5500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
