It replaces the original battery when capacity has faded from normal charge cycles. Dimensions are 84.30 × 64.00 × 4.60mm — a direct physical match for the factory battery bay.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eV1913 and Vivo V17 Neo compatibility:\u003c\/strong\u003e\n    Both model numbers refer to the same hardware platform. They share the same battery bay dimensions, connector pinout, and BMS handshake protocol — one cell covers both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the B-H0 through full charge and discharge cycles on a V17 Neo unit. The BMS accepted the cell without error flags, and the charge IC stepped through CC\/CV phases as expected on the first cycle.\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 build an accurate discharge curve against the new cell before high-current charging runs into an uncalibrated state register.\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 Vivo V17 Neo after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe V17 Neo's modem and display pull sharp current spikes that can drag a new cell's terminal voltage below the BMS cutoff threshold — even when the fuel gauge still shows charge remaining. The fuel gauge IC is calibrated to the old cell's discharge curve, so it misreads the new cell's actual state of charge. This creates a voltage cliff where the phone shuts off well before 0%. One full discharge-to-shutdown followed by an uninterrupted charge to 100% resets the coulomb counter and closes the gap.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD fast charge not activating on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a cell swap, the charge IC on the V17 Neo sometimes holds the new battery in trickle-charge mode for the first session — this is normal BMS behaviour when it detects an uncalibrated cell. Fast charge negotiation via the USB-PD handshake won't escalate until the IC confirms cell impedance is within range. Charge the phone on a standard 5V charger for the first full cycle. After that cycle completes, reconnect the fast charger — the IC should accept the higher current and the phone should confirm fast charge in the notification shade.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391996264538,"sku":"BWCS-BYV170SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391996297306,"sku":"BWCS-BYV170SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391996330074,"sku":"BWCS-BYV170SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BYV170SL-1.webp?v=1779142855","url":"https:\/\/batteryweb.com\/products\/bbk-v1913-replacement-battery-385v-4400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
