It matches the OEM part number VSM3300 and fits the V350C's internal battery bay. Voltage and capacity are spec-matched to the original cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eV350C battery bay fit:\u003c\/strong\u003e\n    The VSM3300 footprint measures 81.40 × 61.00 × 3.80mm — the same dimensions as the factory cell. The connector pinout and BMS handshake align with the V350C's charge IC, so the phone recognises the cell on first boot without triggering a hardware fault.\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 bench, monitoring BMS communication with the charge IC. The protection circuit responded correctly to charge cutoff at 4.35V and did not trip on normal screen-on load current.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one full discharge-to-charge cycle at standard rate. This gives the fuel gauge IC a clean reference curve against the new cell before high-current charging pushes current into an uncalibrated coulomb counter.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the V350C reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe V350C uses a coulomb counter in the fuel gauge IC that builds its model from previous cycle history. When the old cell is removed, that history no longer matches the new cell's discharge curve. The IC keeps using the old model, which causes the percentage to read high or low until it recalibrates. One full uninterrupted discharge and charge cycle at standard rate resets the reference and brings the percentage back in line.\u003c\/p\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 happens when the fuel gauge IC's state-of-charge model drifts from the actual cell voltage. Under modem transmit load or screen brightness spikes, the cell voltage drops sharply — the phone hits the hardware undervoltage cutoff before the software percentage reaches zero. The IC hasn't yet mapped where the new cell's voltage cliff sits. Run the phone down to auto-shutdown once without fast charging, then charge fully to 100% — after that cycle the IC anchors its low-voltage threshold to the correct point on the new cell's curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391791267930,"sku":"BWCS-AMP340SL-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391791300698,"sku":"BWCS-AMP340SL-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391791333466,"sku":"BWCS-AMP340SL-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AMP340SL-1.webp?v=1779142036","url":"https:\/\/batteryweb.com\/products\/cricket-influence-v350c-replacement-battery-385v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
