It fits the OEM BL267 slot directly and restores power to a phone that no longer holds a usable charge. Capacity figure is sourced from product data at 11.55Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVibe K6 fit:\u003c\/strong\u003e\n    The BL267 footprint is specific to the Vibe K6 chassis — 73.00 × 61.40 × 3.80 mm with a matching connector pinout and BMS handshake that the phone's charge IC expects. No other Lenovo Vibe variant shares this exact cell geometry.\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 Vibe K6 board. The BMS negotiated correctly with the charge IC, and protection circuits tripped as expected at low-voltage cutoff — no thermal runaway, no charge refusal on a conditioned cell.\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 and run one full discharge-to-charge cycle. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current charging begins on an uncalibrated reference.\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 Vibe K6 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Vibe K6's fuel gauge IC was calibrated against the original cell's discharge curve. A new cell with a slightly different internal resistance profile hits a voltage cliff under modem or display load that the IC doesn't anticipate. The phone interprets the sudden voltage sag as a valid low-battery shutdown rather than a calibration error. One full uninterrupted discharge cycle — from 100% to automatic shutdown — followed by a full charge resets the coulomb counter reference and typically resolves the premature cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone shows incorrect battery percentage jumping erratically after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eErratic percentage readings on the Vibe K6 after a cell swap are a fuel gauge IC symptom, not a faulty battery. The IC's stored discharge model no longer matches the new cell's actual charge curve, so percentage estimates drift and jump as the algorithm tries to reconcile mismatched data. Android's battery stats cache compounds this — stale calibration data persists across reboots. Clear the battery stats cache in recovery or run two full discharge-charge cycles at room temperature to allow the gauge to rebuild an accurate curve; readings stabilise once the IC has two clean reference cycles to work from.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392070516826,"sku":"BWCS-LVK600SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392070549594,"sku":"BWCS-LVK600SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392070582362,"sku":"BWCS-LVK600SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVK600SL-1.webp?v=1779143561","url":"https:\/\/batteryweb.com\/products\/lenovo-vibe-k6-replacement-battery-385v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
