It replaces the original BL-N2400A when the installed cell has degraded past usable capacity. Voltage and footprint match the original — 78.90 × 57.64 × 3.60 mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eF105 Dual SIM and TD-LTE variants:\u003c\/strong\u003e\n    All three F105 variants share the same battery bay dimensions, connector pinout, and 3.8V nominal voltage rail, so a single BL-N2400A cell covers the full model range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on an F105 unit. The BMS accepted the charge handshake without fault flags, and the protection circuit tripped correctly at the low-voltage cutoff threshold during deep-discharge testing.\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 recalibrate against 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 F105 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe F105 uses a coulomb-counter-based fuel gauge IC that was trained on the discharge curve of the original aged cell. A new cell holds voltage higher for longer before it drops sharply — the fuel gauge reads this as more remaining capacity than actually exists under load. When the modem or screen pulls a high-current burst, the new cell's voltage drops below the system cutoff threshold while the OS still shows 20–30%. One full discharge-to-shutdown followed by a complete uninterrupted charge resets the coulomb counter to the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eF105 not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-polymer cells self-discharge in storage. If the BL-N2400A cell dropped below approximately 2.5V per cell during storage, the BMS enters lockout mode and blocks all current flow to protect the cell from damage. The phone will show no charge indicator and will not power on. Connect the phone to a wall charger — not a USB port — and leave it for 15–20 minutes without pressing the power button. Once the BMS detects the charger has brought the cell above its recovery threshold, the charge indicator will appear and normal boot becomes possible.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392102334554,"sku":"BWCS-GNF105SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392102367322,"sku":"BWCS-GNF105SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392102400090,"sku":"BWCS-GNF105SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GNF105SL-1.webp?v=1779143797","url":"https:\/\/batteryweb.com\/products\/gionee-f105-replacement-battery-38v-2300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
