It restores power to devices that no longer hold a charge or fail to power on. Swap it when the original cell degrades and the phone becomes unreliable through a normal day.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLX370 and LX290 platform fit:\u003c\/strong\u003e\n    These models share the same battery bay geometry, contact pinout, and 3.7V single-cell architecture. The LGIP-430N connector seats and locks identically across the slider and candybar variants in this LG lineup.\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 an LX370 unit. The BMS accepted charge immediately, terminated correctly at 4.2V, and held voltage across standby without anomalous drain.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first installation, run the phone from 100% down to auto-shutdown without interruption, then charge uninterrupted to full. This gives the fuel gauge IC one complete cycle to map the new cell's discharge curve before the percentage readout becomes accurate.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the LX370 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LX370 uses a fuel gauge IC that tracks charge state by coulomb counting against a stored cell profile. When a new cell goes in, the IC still references the old degraded curve. Until it records a full uninterrupted discharge-to-shutdown and full recharge, the percentage it displays is calculated against the wrong baseline. One complete cycle resets that reference point and the percentage readout stabilises.\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 happens when the fuel gauge IC has not yet recalibrated to the new cell's voltage curve. The phone reads 25% remaining but the cell voltage under screen or modem load drops below the shutdown threshold before the gauge catches up. It is not a faulty cell — it is a calibration gap. Run one full uninterrupted discharge cycle and the cutoff point will align correctly with the displayed percentage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405133807706,"sku":"BWCS-LX370SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405133840474,"sku":"BWCS-LX370SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405133873242,"sku":"BWCS-LX370SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LX370SL-1.webp?v=1779370263","url":"https:\/\/batteryweb.com\/products\/lg-lx370-replacement-battery-37v-650mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
