It fits directly into the Edge 30 Pro chassis and connects to the same flex ribbon and BMS board as the original cell. Capacity is 4200mAh (16.34Wh), matching the OEM specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEdge 30 Pro platform fit:\u003c\/strong\u003e\n    The XT2205-3 uses a 3.89V nominal cell with a specific connector pitch and BMS handshake tied to Motorola's charge IC. This cell matches that voltage rail and connector, so the charge IC initialises without throwing a battery authentication error.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through Motorola's USB-PD fast charge sequence and monitored BMS response across the full charge curve. The protection circuit held cutoff at the correct upper voltage and did not trip during modem-load discharge cycles.\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 map the new cell's actual discharge curve before high-current charging pushes current into an uncalibrated coulomb counter — which is the main cause of erratic percentage readings after a cell swap.\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 Edge 30 Pro after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Edge 30 Pro's Snapdragon 8 Gen 1 pulls hard under 5G modem activity and high-refresh display loads. A new cell with an uncalibrated fuel gauge IC will report 25% remaining while actual cell voltage has already sagged below the shutdown threshold — typically 3.4V under load on this platform. The SoC cuts power to protect the cell before the OS reads the drop. One full slow-charge cycle recalibrates the coulomb counter and closes this gap.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD fast charge not working on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Edge 30 Pro's charge IC sends a handshake to confirm cell identity before enabling 68W TurboPower. On a freshly installed cell, the BMS has not yet completed its first full charge handshake, so the charge IC falls back to standard 5V\/2A input. This is not a fault — it resolves after the first complete charge cycle. If fast charge still does not engage after two full cycles, confirm the cable supports USB-PD at 20V and re-seat the battery flex connector.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391791562842,"sku":"BWCS-MXE253SL-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391791595610,"sku":"BWCS-MXE253SL-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391791628378,"sku":"BWCS-MXE253SL-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MXE253SL-1.webp?v=1779142036","url":"https:\/\/batteryweb.com\/products\/motorola-xt2205-3-replacement-battery-389v-4200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
