It replaces OEM part numbers LGIP-490A and SBPL0095501. If your original cell no longer holds a charge or the phone shuts down unexpectedly, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLX600 and Lotus compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, connector pinout, and BMS handshake protocol — that is why one cell fits both. The 51.85 × 37.65 × 5.13mm form factor seats flush with no modification needed.\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 LX600 hardware. The BMS accepted the charge IC handshake on first contact, voltage held steady at 3.7V nominal, and the protection circuit triggered 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 install, disable any fast-charge accessories and run one full discharge-to-charge cycle. This lets the fuel gauge IC map the new cell's actual discharge curve before the phone starts making load decisions based on it.\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 LX600 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LX600's fuel gauge IC retains the discharge curve of the original cell. When a new cell is installed, the stored curve no longer matches actual cell behaviour. Under load — screen backlight plus RF transmission — voltage drops faster than the gauge predicts, and the phone cuts power before the percentage reaches zero. This is not a defective battery. One full discharge down to automatic shutoff followed by a complete charge resets the coulomb counter and resolves the mismatch. After that cycle, percentage readings stabilise.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone not powering on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage. If this battery shipped or sat unused long enough to drop below 2.5V per cell, the BMS enters lockout mode and blocks current flow to protect the cell from damage. The phone will show no response — no boot screen, no charging indicator. Connect it to a wall adapter and leave it for 15–20 minutes without attempting to power it on. Once the BMS detects sufficient voltage recovery, it releases the lockout and the charge indicator appears. If nothing shows after 30 minutes, check the adapter is delivering at least 5V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405259276378,"sku":"BWCS-LVX600SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405259309146,"sku":"BWCS-LVX600SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405259341914,"sku":"BWCS-LVX600SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVX600SL-1.webp?v=1779370368","url":"https:\/\/batteryweb.com\/products\/lg-lx600-replacement-battery-37v-850mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
