All three models share the same battery form factor: 53.00 × 33.90 × 5.70mm with a matched voltage rail. Capacity is rated at 4.44Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eProfessional, Professional CAMO, Professional EM compatibility:\u003c\/strong\u003e\n    These three variants share an identical battery bay, connector pinout, and 3.7V supply rail. Swapping between models is not an issue — the cell and BMS interface are the same across the series.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the Professional platform. The BMS accepted the charge cycle without fault, and cutoff voltage at both ends of the curve matched OEM spec.\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 for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current charging pushes 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\"\u003eWhy the Mobiado Professional reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC in the Professional uses a coulomb counter calibrated to the original cell's discharge curve. A new cell has a different internal resistance profile, so the counter's reference points no longer match real charge state. The phone will display inaccurate percentages — sometimes jumping or plateauing — until the IC relearns the curve. Run one full discharge down to automatic shutdown, then charge uninterrupted to 100% to force a recalibration cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity fault. Under screen-on or call load, the cell voltage drops sharply below the BMS cutoff threshold even though the reported percentage still looks safe. It happens most on a new cell that hasn't been through a calibration cycle — the fuel gauge IC is using stale reference data. Run one full discharge-to-shutdown cycle, then charge to 100%; the cutoff events should stop once the IC maps the new cell's voltage curve correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404286656602,"sku":"BWCS-DEP215SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404286689370,"sku":"BWCS-DEP215SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404286722138,"sku":"BWCS-DEP215SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEP215SL-1.webp?v=1779369550","url":"https:\/\/batteryweb.com\/products\/mobiado-professional-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
