It replaces OEM part numbers BL-T30 and EAC63458501. Fit this cell when the original battery no longer holds a charge or causes unexpected shutdowns.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBL-T30 platform compatibility:\u003c\/strong\u003e\n    The M320, K10 Power, and X Allumage 2 all draw from the same 3.85V rail and use the same connector pinout and BMS handshake. That shared platform spec is why one cell covers all three devices.\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 the M320 platform. The BMS accepted the cell without fault codes, held voltage through a full screen-on load cycle, and charged correctly via the device's charge IC.\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 and run one complete discharge-charge cycle at standard rate. This lets the fuel gauge IC map its coulomb counter to the new cell's discharge curve before high-current charging begins on 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 LG M320 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe LG M320's fuel gauge IC uses a stored discharge curve from the old cell. A new 4500mAh Li-Polymer cell has a steeper voltage cliff at lower states of charge than the degraded cell it replaced. When the modem fires a high-current burst or the screen peaks brightness, voltage sags below the BMS cutoff threshold — the phone interprets this as empty and shuts off. The fix is one full uninterrupted discharge to near-zero, then a full charge at standard rate. After that cycle, the coulomb counter recalibrates and the shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB fast charge not working on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fast-charge handshake on the M320 runs a brief negotiation between the charge IC and the battery BMS before the device accepts elevated current. On the first cycle with a new cell, the BMS may refuse the high-current handshake until it has completed one baseline charge at standard rate. Connect via the original LG charging cable, let it complete a full standard-rate charge, then unplug and replug. Fast charge should activate on the subsequent session once the BMS registers a full baseline cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392063111258,"sku":"BWCS-LKM320XL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392063144026,"sku":"BWCS-LKM320XL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392063176794,"sku":"BWCS-LKM320XL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LKM320XL-1.webp?v=1779143471","url":"https:\/\/batteryweb.com\/products\/lg-m320-replacement-battery-385v-4500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
