It replaces a degraded original cell that can no longer hold charge under typical call, screen, and data load. Dimensions are 100.00 x 41.45 x 4.50mm — measure your original before fitting if you are unsure.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOrange Yumo G740 fitment:\u003c\/strong\u003e\n    The G740 uses a fixed connector and BMS handshake tied to the 3.8V nominal rail. Swapping a cell outside that voltage spec causes the charge IC to reject the battery or report incorrect state-of-charge from the first cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and load cycles on the G740 platform. The BMS accepted the new cell without fault codes, and the charge IC progressed through CC and CV phases normally without cutoff errors.\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\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh cell with a different internal resistance profile hits a voltage cliff earlier than the fuel gauge IC expects. Under modem transmission bursts or screen-at-full-brightness load, the cell voltage drops below the BMS cutoff threshold even when the OS shows 25% remaining. The fuel gauge IC is still calibrated to the old cell's discharge curve, so the percentage reading lags behind actual cell state. One full discharge to auto-shutdown followed by a complete charge cycle resets the coulomb counter and resolves premature cutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOS reporting wrong battery percentage after cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe G740's fuel gauge IC uses a stored discharge curve to calculate remaining capacity. When the original cell is replaced, that stored curve no longer matches the new cell's behaviour. The result is percentage jumps — often skipping from 40% to 10% — or a reading that freezes and then drops suddenly. Fully discharge the phone until it shuts off automatically, then charge uninterrupted to 100% without fast charging enabled; the coulomb counter resets to the new cell's actual curve at that point.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404288327770,"sku":"BWCS-HUT300XL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404288360538,"sku":"BWCS-HUT300XL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404288393306,"sku":"BWCS-HUT300XL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HUT300XL-1.webp?v=1779369643","url":"https:\/\/batteryweb.com\/products\/para-orange-yumo-g740-replacement-battery-38v-2300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
