It replaces the original cell when capacity has faded or the battery no longer holds a usable charge. Fits the BEE-001 chassis and uses OEM part number BEE-003.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSwitch 2 BEE-001 compatibility:\u003c\/strong\u003e\n    The BEE-001 board uses a single-cell Li-Polymer architecture with a dedicated fuel gauge IC that tracks coulomb counting. This replacement cell matches the original voltage rail and connector pinout so the BMS handshake completes without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge and discharge cycles on the BEE-001 board and confirmed the charge IC accepted the new cell, the fuel gauge registered correctly, and the protection circuit tripped at the correct low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on Switch 2:\u003c\/strong\u003e\n    After installing, run one complete wireless play session to automatic low-battery shutdown before recharging. The fuel gauge IC on the BEE-001 board sets its empty reference point against the first full discharge — skipping this step causes inaccurate percentage readings from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFuel gauge jumping or freezing after cell swap on the Switch 2\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BEE-001 uses a coulomb-counting fuel gauge IC that builds a model of the cell's discharge curve over time. When you fit a new cell, that stored model no longer matches the new cell's actual curve, so the reported percentage can jump, freeze, or drop suddenly. This resolves across three to five full charge-discharge cycles as the IC rewrites its internal table. Until then, treat the percentage as approximate and watch for the low-battery warning rather than the number itself.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSwitch 2 not charging the new cell at full rate\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Switch 2 charge IC applies a conservative current limit when it first sees an unfamiliar cell — this is a built-in safety behaviour, not a fault with the replacement battery. The charge rate typically steps up to the full rate after the first complete cycle once the IC confirms the cell is stable. If the console is still charging slowly after two full cycles, check that the USB-C port is delivering at least 5V\/1.5A — underpowered chargers lock the IC into trickle mode regardless of cell state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377528471642,"sku":"BWCS-NTS200SL-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377528504410,"sku":"BWCS-NTS200SL-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377528537178,"sku":"BWCS-NTS200SL-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NTS200SL-1.webp?v=1778767205","url":"https:\/\/batteryweb.com\/products\/nintendo-bee-001-replacement-battery-37v-4800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
