It fits phones where the original cell no longer holds voltage under screen or modem load. Dimensions are 70.75 × 51.20 × 4.70mm — measure your original before ordering if unsure.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSmart Turbo 7 \/ VFD 500 platform fit:\u003c\/strong\u003e\n    All three model variants — Smart Turbo 7, VFD 500, and V500 — share the same battery bay geometry, connector pinout, and BMS communication protocol, which is why a single TLi020F1 cell covers the whole family.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge, screen-on load, and modem-active draw. The BMS held the 3.8V nominal rail without tripping into protection mode under combined screen and data load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After fitting this cell, disable fast charging and run one full discharge down to automatic shutdown, then charge to 100% uninterrupted. This lets the phone's fuel gauge IC map the new cell's discharge curve before reporting accurate percentages.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Smart Turbo 7 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe phone uses a coulomb counter in the fuel gauge IC that was calibrated to the old cell's discharge curve over hundreds of cycles. Swap in a new cell and that stored curve no longer matches actual cell behaviour — the IC is still using the degraded profile. This causes the percentage display to jump or read higher than reality until the system relearns. One complete discharge-to-shutdown followed by a full uninterrupted charge to 100% forces the IC to rebuild its reference curve against the new cell.\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 cell voltage drops sharply under modem or display load — a voltage cliff the fuel gauge IC did not anticipate because it hasn't finished recalibrating. The BMS trips to protect the cell before the percentage counter reaches zero. It is not a faulty cell. Let the phone shut down naturally at that point, then charge fully without interruption. After two full cycles the IC will have enough data to predict the voltage cliff accurately and the shutdowns will stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404274663514,"sku":"BWCS-OT704SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404274696282,"sku":"BWCS-OT704SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404274729050,"sku":"BWCS-OT704SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OT704SL-1.webp?v=1779369616","url":"https:\/\/batteryweb.com\/products\/vodafone-smart-turbo-7-replacement-battery-38v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
