It matches the OEM voltage rail and connector, so it installs without modification. Capacity is drawn from product data at 5.55Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVX7000 and VX-7000 fitment:\u003c\/strong\u003e\n    Both model designations use the same battery bay, connector pinout, and BMS handshake — one cell covers either variant. The OEM part numbers SBPL0073001 and SBPL0073101 are interchangeable across this production run.\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 VX7000 platform. The BMS accepted the cell without fault codes, and the charge IC completed a full cycle without thermal cutoff or premature termination.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installing this cell, run one complete discharge down to auto-shutdown before charging back to 100%. The VX7000's fuel gauge IC is calibrated to the old cell's discharge curve — skipping this step causes the percentage readout to drift or jump erratically from the first session.\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 VX7000 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe VX7000's fuel gauge IC tracks charge state using a coulomb counter mapped to the original cell's discharge curve. A new cell has a slightly different voltage-to-capacity profile, so the reported percentage diverges from actual cell voltage under load. When the modem transmits or the backlight fires at full brightness, current draw spikes and cell voltage drops faster than the gauge expects. The BMS sees voltage fall below its cutoff threshold while the screen still shows 25% — and it shuts the phone down. One full discharge-recharge cycle resets the coulomb counter and eliminates this mismatch.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eErratic percentage readings — jumping from 60% to 40% in seconds, or stalling at a fixed number for long periods — are the fuel gauge IC recalibrating against an unfamiliar discharge curve. The IC uses stored charge-state data from the previous cell, and that data no longer matches what the new cell is actually delivering. This is not a fault in the replacement cell. Discharge the phone fully to automatic shutdown, then charge uninterrupted to 100% — after that single cycle, the gauge IC anchors to the new cell's curve and readings stabilise.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405263601754,"sku":"BWCS-VX7000XL-1","price":23.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43405263634522,"sku":"BWCS-VX7000XL-2","price":26.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43405263667290,"sku":"BWCS-VX7000XL-3","price":28.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VX7000XL-big.webp?v=1779370369","url":"https:\/\/batteryweb.com\/products\/lg-vx7000-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
