It fits the same slot, uses the same connector, and works with the phone's existing charge controller. Capacity is rated at 6.84Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSmart Speed 6 \/ VF795 fitment:\u003c\/strong\u003e\n    The VF-795 uses a fixed 3.8V nominal rail with a five-pin flex connector tied to the BMS. Any replacement cell must match that voltage and present the correct thermistor resistance to the charge IC — this cell does both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a VF-795 unit and confirmed the BMS accepted the handshake on first connect, charge current ramped correctly through CC\/CV phases, and no false temperature fault codes were triggered.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installing this cell, disable fast charging and run one full discharge-charge cycle before resuming normal use. This lets the fuel gauge IC map its coulomb counter to the new cell's discharge curve before high-current charging pushes current into an uncalibrated state.\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 Smart Speed 6 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe VF-795 fuel gauge IC retains the discharge curve of the old, degraded cell after a swap. When the new cell hits the voltage range where the old cell used to collapse, the IC can misread remaining capacity and signal a shutdown — even though real charge remains. This is a calibration mismatch, not a fault with the replacement cell. Run two full discharge-charge cycles without interruption and the coulomb counter will remap to the new cell's curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone reports wrong battery percentage after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Smart Speed 6 stores a learned discharge profile in the fuel gauge IC from the previous cell. A new 1800mAh cell presents a different internal resistance and a steeper voltage curve near full charge — so the IC reads incorrectly from the first boot. The fix is straightforward: charge to 100%, let the phone drain to automatic shutdown, then charge back to 100% uninterrupted. After that full cycle, percentage reporting stabilises within a few percent of actual charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392107118682,"sku":"BWCS-VF795SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392107151450,"sku":"BWCS-VF795SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392107184218,"sku":"BWCS-VF795SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VF795SL-1.webp?v=1779143816","url":"https:\/\/batteryweb.com\/products\/vodafone-smart-speed-6-replacement-battery-38v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
