The cell matches the original dimensions at 53.16 × 33.77 × 5.34mm, so it seats correctly in the battery bay. Drop capacity is 3.89Wh — identical to the stock specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBBM and SC series compatibility:\u003c\/strong\u003e\n    These four models share the same battery bay dimensions, 3.7V nominal voltage rail, and connector pinout. One cell covers all of them because the BMS handshake and charge termination voltage are consistent across the platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a BBM 410 chassis. The BMS accepted charge termination at 4.2V, protection tripped correctly on overcurrent, and the fuel gauge IC tracked state-of-charge without error flags after the second full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one full discharge-to-charge cycle. This gives the fuel gauge IC time to map the new cell's discharge curve before the charge IC pushes higher current into an uncalibrated cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the BBM 410 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC still holds the old cell's discharge curve in memory. A new cell with different internal resistance hits a voltage cliff under modem or screen load before the gauge reaches 0%. The phone reads 25% but the actual cell voltage drops below the BMS cutoff threshold under load. One full discharge-to-charge cycle forces the coulomb counter to recalibrate against the real cell, and the shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice won't power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells in storage self-discharge slowly. If the cell voltage drops below roughly 2.5V, the BMS enters lockout mode and blocks current flow to protect the cell from damage. The phone shows nothing — no charging animation, no response. Connect it to a charger and leave it for 15–20 minutes without pressing the power button; the charge IC trickle-charges the cell back above the BMS recovery threshold, typically 2.9V, at which point the BMS unlocks and normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405068861530,"sku":"BWCS-WSV290SL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405068894298,"sku":"BWCS-WSV290SL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405068927066,"sku":"BWCS-WSV290SL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WSV290SL-1.webp?v=1779369899","url":"https:\/\/batteryweb.com\/products\/swisstone-bbm-410-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
