It fits the same connector and battery bay as the original LGIP-520NV. Capacity is 800mAh (2.96Wh) — matching the factory spec for these handsets.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eUN150 \/ VN150 platform compatibility:\u003c\/strong\u003e\n    The UN150 Envoy, VN150 Revere, and LG-VN150PP variants share the same 3.7V single-cell architecture, battery bay dimensions (49.00 × 34.20 × 5.80mm), and connector pinout. One cell covers the full group.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a VN150 Revere. The BMS accepted charge from the device's internal charge IC without interruption, and the protection circuit tripped correctly at the low-voltage cutoff threshold under a simulated load drain.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    On first use after installation, run the phone down to automatic shutdown on a single discharge, then charge to 100% uninterrupted. This gives the fuel gauge IC one full reference cycle against the new cell's discharge curve before normal use.\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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff problem. The fuel gauge IC in the UN150 and VN150 was calibrated against the old, degraded cell — its voltage-to-percentage map no longer matches the new cell's discharge curve. Under load from the screen or a call, the cell voltage drops faster than the gauge predicts, hitting the hardware cutoff before the display percentage reaches zero. The fix is one full uninterrupted discharge-to-shutdown followed by a full charge. After that cycle, the coulomb counter has a clean reference and shutdowns at low percentage stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after sitting in storage with a new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells shipped and stored for extended periods can self-discharge below 2.5V per cell. At that voltage, the BMS enters lockout mode to prevent damage — the phone will show no response to the power button and no charge indicator when plugged in. Connect the phone to a wall charger and leave it undisturbed for 15–20 minutes without pressing anything. The charge IC trickle-charges the cell back above the BMS recovery threshold, typically around 2.9V, at which point the BMS unlocks and normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405126369370,"sku":"BWCS-VX5600SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405126402138,"sku":"BWCS-VX5600SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405126434906,"sku":"BWCS-VX5600SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VX5600SL-1.webp?v=1779370244","url":"https:\/\/batteryweb.com\/products\/verizon-un150-envoy-replacement-battery-37v-800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
