It matches the original cell dimensions at 86.60 x 64.00 x 4.60mm for a direct fit within the chassis. Capacity is 18.87Wh — identical to the stock specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMoto G73 5G \/ XT2237 fitment:\u003c\/strong\u003e\n    Both model designations run the same power rail, connector pinout, and BMS handshake protocol, so one cell covers the full XT2237 production run regardless of regional variant.\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 G73 5G unit. The BMS accepted the cell without fault codes, and the charge IC stepped through trickle, CC, and CV phases as expected.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fast charge protocol:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and complete one full discharge-charge cycle at standard rate. This lets the fuel gauge IC recalibrate its coulomb counter against the new cell's discharge curve before high-current charging begins.\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% after fitting a replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe G73 5G's fuel gauge IC stores a discharge curve calibrated to the original cell. A new cell has different internal resistance and a slightly different voltage-to-capacity curve. Under modem or display load, voltage can sag below the shutdown threshold even when the OS still reports 20–30% remaining. One complete slow-rate discharge down to automatic cutoff — without fast charging — resets the coulomb counter and aligns the gauge to the replacement cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB fast charge not accepted on first cycle after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome replacement cells present slightly higher impedance on the first cycle, and the G73 5G's charge controller defaults to standard 5V\/1A input when it cannot confirm the cell is within expected impedance range. This is not a compatibility fault — it is a protection response. Charge once at standard rate to completion, then reconnect with your fast charger. The controller will renegotiate the USB-PD handshake and step up current delivery once the cell has been conditioned.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391792119898,"sku":"BWCS-MXG730SL-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391792152666,"sku":"BWCS-MXG730SL-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391792185434,"sku":"BWCS-MXG730SL-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MXG730SL-1.webp?v=1779142036","url":"https:\/\/batteryweb.com\/products\/motorola-moto-g73-5g-replacement-battery-389v-4850mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
