It matches the OEM part numbers ADBAT-001 and ADBAT-011. Swap it in when your original cell no longer holds a charge through a full shoot.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHero 9 \/ 10 \/ 11 platform fit:\u003c\/strong\u003e\n    All three cameras share the same AHDBT-901 cell form factor, voltage rail, and BMS handshake protocol. One replacement covers all three bodies without any wiring or adapter changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Hero 11 body and a third-party dual charger. The BMS accepted the cell on both charge paths, balanced correctly, and held voltage within the expected discharge curve through multiple cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on a Hero body:\u003c\/strong\u003e\n    Insert this cell into the camera and run one full charge cycle through the camera body before heavy use. The Hero 9–11 BMS maps its battery-remaining display to a discharge curve learned during that first in-body charge — skipping this step causes erratic percentage readouts.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Hero 11 shows a dead battery indicator on a freshly charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Hero 11 reads battery state by comparing real-time cell voltage against a stored discharge curve. A new cell that has never been charged inside the camera body has no mapped curve on record, so the firmware defaults to a worst-case low-battery reading. This is not a fault with the cell. One full charge cycle inside the camera body — not just via an external charger — writes the reference curve and clears the false indicator. After that cycle, the percentage display tracks the actual cell state correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or resetting mid-shoot on the Hero 9 or Hero 10\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA replacement cell has a slightly different discharge curve than the OEM cell the camera originally calibrated against. When the camera's fuel gauge algorithm hits a voltage point it doesn't expect, it recalculates sharply — showing a sudden jump or drop in percentage. This is a calibration gap, not a failing cell. Run two full charge-discharge cycles inside the camera body to let the BMS re-anchor its voltage thresholds to the new cell. After the second cycle, readings stabilise to within a few percent of actual charge remaining.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333616435290,"sku":"BWCS-GDB900MX-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333616468058,"sku":"BWCS-GDB900MX-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333616500826,"sku":"BWCS-GDB900MX-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GDB900MX-1.webp?v=1778212976","url":"https:\/\/batteryweb.com\/products\/gopro-ahdbt-901-replacement-battery-385v-1720mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
