It matches the OEM voltage rail and connector spec so the BIOS can communicate with the pack's BMS. Swap it in when the original cell no longer holds a charge or the OS reports degraded capacity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eID47H series compatibility:\u003c\/strong\u003e\n    These models share the same 11.1V three-cell architecture, connector pinout, and BMS handshake protocol. A single pack covers the full ID47H line because Gateway used one battery platform across all ID47H variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and discharge on the ID47H platform. The BMS communicated correctly with the notebook's fuel gauge IC, and charge current tapered normally as the cell approached 100%.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the ID47H:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to hibernate cutoff — do not interrupt it. Then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the false health warning the firmware throws after any 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 immediately after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Gateway ID47H BIOS stores charge history and cycle count data from the previous pack in its battery learn table. When a new cell arrives with a clean EEPROM, the firmware compares it against that old data and flags it as unhealthy. This is a firmware artefact — not a fault with the replacement cell. Run the full calibration cycle described above and the health indicator will update correctly within one to two charge cycles.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down abruptly at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC still holds calibration data from the degraded original cell. Under full CPU and display load, the new cell's actual voltage at that state-of-charge is higher than the old cell's was — so the gauge reads the cutoff point too early. The fix is a complete discharge-to-hibernate cycle followed by a full uninterrupted charge. After two or three of those cycles, the fuel gauge IC recalibrates against the new cell's voltage curve and the shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409783390298,"sku":"BWCS-AC3830NB-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409783423066,"sku":"BWCS-AC3830NB-2","price":85.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409783455834,"sku":"BWCS-AC3830NB-3","price":94.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AC3830NB-1.webp?v=1779580817","url":"https:\/\/batteryweb.com\/products\/gateway-id47h-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
