It fits the LG X Style, K200, K200ds, and K200dsK, along with several other K200-series variants. When the original cell loses capacity or fails to hold charge, this unit restores the phone to normal operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eK200 platform compatibility:\u003c\/strong\u003e\n    The X Style and K200-series devices share the same battery bay dimensions (76.48 × 47.90 × 4.15mm), connector pinout, and BMS handshake protocol — which is why a single cell covers all variants in this family.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the BL-41A1HB through charge and load cycles on K200-series hardware. The BMS accepted the charge IC handshake without error flags, and the protection circuit tripped correctly at the low-voltage cutoff threshold.\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 full discharge-charge cycle at standard rate. 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 LG X Style after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a defective cell. The fuel gauge IC on the K200 platform was calibrated to the old cell's discharge curve. A new cell has a different internal resistance profile, so the IC underestimates remaining capacity under load — particularly when the modem or display draws a current spike. The phone reads 25% but the modelled voltage drops below the shutdown threshold. One full uninterrupted discharge-charge cycle at standard rate re-anchors the coulomb counter to the new cell. After that cycle, shutdowns at partial charge typically stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOS reporting an incorrect or jumping battery percentage after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Android fuel gauge IC on the K200 series stores learned capacity data from the previous cell in non-volatile memory. After swapping in a new 2000mAh cell, that stored data no longer matches the actual cell chemistry. The result is erratic percentage readings — sometimes jumping 5–10% in either direction with no load change. To force a recalibration, drain the phone until it shuts off automatically, then charge uninterrupted to 100% without removing the cable. Check the percentage stabilises at 4.35V at termination before trusting the readout.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392038994010,"sku":"BWCS-LKK200SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392039026778,"sku":"BWCS-LKK200SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392039059546,"sku":"BWCS-LKK200SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LKK200SL-1.webp?v=1779143085","url":"https:\/\/batteryweb.com\/products\/lg-x-style-replacement-battery-38v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
