It fits the M250N, K121K, X400, and 18 additional variants sharing the same battery bay and connector. If your K10 2017 drains fast, shuts down unexpectedly, or won't hold a charge, the original BL-46G1F cell has likely degraded beyond usable capacity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eK10 2017 variant compatibility:\u003c\/strong\u003e\n    The M250N, K121K, and X400 all run the same 3.85V power rail and use the identical BL-46G1F form factor — same footprint at 78.00 × 52.06 × 4.70mm, same connector pinout, same BMS handshake protocol. No modification needed across this variant group.\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 discharge cycles on the K10 2017 platform. The BMS accepted the cell without error flags, thermal behaviour stayed within normal range during charge, and the fuel gauge IC began tracking discharge current correctly after the first full cycle.\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-to-charge cycle. This lets the fuel gauge IC map its coulomb counter against the new cell's actual 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 K10 2017 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still calibrated to the old, degraded cell's voltage curve. The new cell has a steeper voltage cliff under modem or screen load — the IC reads 25% state of charge, but actual cell voltage drops below the shutdown threshold the moment current draw spikes. The phone cuts power before the percentage reaches zero. One full discharge cycle without fast charging forces the coulomb counter to re-anchor to the new cell's actual capacity endpoint at roughly 3.0V cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eK10 2017 reporting wrong battery percentage after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LG K10 2017 uses a fuel gauge IC that stores learned capacity data from the previous cell. After swapping to the BL-46G1F replacement, the stored data no longer matches the new cell's discharge profile, so percentage readings jump or stall — commonly freezing at 50% or dropping suddenly. This is not a fault in the replacement cell. Discharge the phone until it shuts down automatically, then charge uninterrupted to 100% without removing the cable early. That single cycle resets the IC's reference points and the percentage display stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392054165594,"sku":"BWCS-LKM250HL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392054198362,"sku":"BWCS-LKM250HL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392054231130,"sku":"BWCS-LKM250HL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LKM250HL-1.webp?v=1779143471","url":"https:\/\/batteryweb.com\/products\/lg-k10-2017-replacement-battery-385v-2700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
