It carries OEM part number BL-G015 and matches the original cell's dimensions at 51.13 × 50.36 × 4.45mm. Swap it in when the original cell no longer holds enough charge to get through a normal day.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGN320 \/ GN380 \/ GN205 compatibility:\u003c\/strong\u003e\n    All three models run the same 3.7V single-cell architecture and use the same BL-G015 connector footprint. The BMS handshake is identical across the range, so one cell covers all three without modification.\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 GN320 platform. The BMS accepted the cell on the first connect, charge termination triggered correctly at 4.2V, and low-voltage cutoff engaged cleanly before the cell dropped below safe limits.\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 any fast-charge mode and run one full discharge-to-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell.\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 GN320 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe GN320's fuel gauge IC stores a discharge model built around the original cell's impedance. A new cell has a different internal resistance profile, so the IC misjudges the remaining voltage under modem or screen load. The phone reads 25% but the cell voltage collapses under that draw and the BMS cuts power. One full discharge cycle — drain to automatic cutoff, then charge uninterrupted to 100% — forces the coulomb counter to recalibrate against the new cell. After that cycle, percentage readings stabilise.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGN320 not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If this cell's voltage has dropped below approximately 2.5V, the BMS will have engaged a lockout to prevent unsafe charging. Plugging straight into a wall charger may show no response at all. Connect the phone to a low-current USB source — a PC port or a 5V\/500mA adapter — and leave it for 15–20 minutes before attempting to power on. This trickle current is enough to bring the cell above the BMS re-enable threshold, after which normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404257919066,"sku":"BWCS-GNN320SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404257951834,"sku":"BWCS-GNN320SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404257984602,"sku":"BWCS-GNN320SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GNN320SL-1.webp?v=1779369511","url":"https:\/\/batteryweb.com\/products\/gionee-gn320-replacement-battery-37v-1550mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
