It replaces OEM parts TLP17J18, TPN17E24, TLJ17G29, and 396272 on a direct swap. Fit these four models share the same battery bay geometry, connector orientation, and fuel gauge IC protocol.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eView Prime \/ Upulse platform compatibility:\u003c\/strong\u003e\n    All four models run the same 3.85V power rail, use an identical 74.54 × 61.56 × 3.74mm cell footprint, and communicate with the same fuel gauge IC over the same bus. One cell covers the full range without any connector or BMS mismatch.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge cycle on a View Prime unit. The BMS accepted the charge handshake on the first connection, the fuel gauge IC reported state-of-charge without error flags, 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    After installation, disable fast charging and run one complete discharge-to-charge cycle at standard rate. The fuel gauge IC on the View Prime calibrates its coulomb counter against the cell's actual discharge curve — skipping this step leaves the IC reading against the old cell profile and causes early percentage jumps.\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 Wiko View Prime after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage-cliff issue, not a capacity problem. When the modem transmits or the screen runs at full brightness, current draw spikes sharply. If the fuel gauge IC is still calibrated to the old cell's discharge curve, it reports 25% remaining while the actual cell voltage has already dropped below the safe operating threshold. The phone shuts off to protect the BMS — not because the new cell is faulty. One full slow discharge-charge cycle resets the coulomb counter and eliminates the false floor. After that cycle, percentage readings should track actual voltage within ±3%.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB fast charging not recognised after fitting the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge cycle, the charge IC on the View Prime negotiates current delivery based on cell impedance readings. A new cell has higher impedance than a worn one, and the IC can respond by falling back to standard 5V charging rather than accepting the fast-charge handshake. This is not a fault — it clears after the first full cycle as the IC re-profiles the cell. If fast charging still does not engage after two full cycles, check the cable and charger can negotiate the correct protocol by testing with a known-good USB-PD source.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392002752602,"sku":"BWCS-WKP718SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392002785370,"sku":"BWCS-WKP718SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392002818138,"sku":"BWCS-WKP718SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WKP718SL-1.webp?v=1779142874","url":"https:\/\/batteryweb.com\/products\/wiko-view-prime-replacement-battery-385v-2900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
