It fits the Wiko View 3 Lite and W-V800 smartphones. The cell matches OEM dimensions at 80.20 × 63.65 × 4.54mm, so it seats correctly under the original flex connector without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eView 3 Lite and W-V800 fitment:\u003c\/strong\u003e\n    Both model designations share the same chassis and battery bay. The 466479 part number covers the full production run of this platform — same connector pin-out, same BMS handshake voltage thresholds, one cell covers both variants.\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 View 3 Lite platform and confirmed the BMS negotiated correctly at each charge phase. Cutoff voltage held at 4.35V on the high end; the protection circuit tripped cleanly at the low-voltage threshold without triggering a hard fault.\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 for one complete discharge-charge cycle. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current charging is applied to 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 View 3 Lite after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the fuel gauge IC is still calibrated to the old cell's discharge curve, it misreads the new cell's state of charge by a significant margin. A fresh 3900mAh cell has a steeper voltage cliff under modem and display load than the degraded cell the phone learned on. The phone reads 25% but the cell voltage has already dropped below the point where it can sustain the screen and radio simultaneously. Running one full discharge to auto-off, then charging uninterrupted to 100%, forces the coulomb counter to remap against the new cell and eliminates the false cliff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice won't power on after sitting in storage with a flat battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells discharged below approximately 2.5V trigger a BMS lockout to prevent cell damage — the phone will show nothing when you press the power button. Standard charging will not clear this state because the charge IC won't pass current to a cell the BMS has locked out. Connect the phone to a low-current USB source (a 5V 500mA port, not a fast charger) and leave it for 20–30 minutes without pressing anything. The BMS uses trickle current to bring the cell voltage above the lockout threshold, after which normal charging resumes. Confirm recovery by checking that the charging indicator appears within 30 minutes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391928893530,"sku":"BWCS-WKV800SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391928926298,"sku":"BWCS-WKV800SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391928959066,"sku":"BWCS-WKV800SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WKV800SL-1.webp?v=1779142694","url":"https:\/\/batteryweb.com\/products\/wiko-view-3-lite-replacement-battery-385v-3900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
