It fits the GN151 smartphone directly, matching the original connector, physical footprint (71.70 × 56.41 × 4.23 mm), and voltage rail. Swap it in when the original cell can no longer hold charge through a normal day of calls and messaging.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGN151 fitment:\u003c\/strong\u003e\n    The GN151 runs a single-cell 3.7V Li-ion architecture. This replacement matches that voltage rail exactly, uses the same BL-C008C connector orientation, and communicates with the phone's charge IC 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 full charge and discharge on a GN151 unit. The BMS accepted the charge profile correctly, voltage held steady under screen-on and active call load, and the protection circuit tripped at the expected cutoff points.\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 complete discharge-to-charge cycle before normal use. The GN151's fuel gauge IC was calibrated to the old cell's discharge curve — one full cycle lets it map the new cell and report percentage accurately.\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 GN151 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh Li-ion cell has a steeper voltage cliff than a worn cell — the GN151's fuel gauge IC is still reading the old, gradual curve. Under modem or display load, the new cell's voltage drops faster than the IC expects, and the phone shuts down before it reports zero. This is a calibration gap, not a faulty battery. Run one full discharge from 100% to automatic shutdown, then charge to 100% uninterrupted. After that cycle, the coulomb counter resets to the new cell's actual curve and shutdowns at low percentage stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGN151 not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage — if this battery sat long enough to drop below 2.5V per cell, the BMS enters a lockout state to prevent damage and the phone will not respond to the power button. Connect the phone to a wall charger, not a USB port, and leave it for 20–30 minutes without pressing anything. The charge IC delivers a trickle current that brings the cell back above the BMS re-enable threshold. Once the screen shows a charging indicator, the BMS has cleared and normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404224299098,"sku":"BWCS-GNN151SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404224331866,"sku":"BWCS-GNN151SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404224364634,"sku":"BWCS-GNN151SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GNN151SL-1.webp?v=1779369391","url":"https:\/\/batteryweb.com\/products\/gionee-gn151-replacement-battery-37v-1550mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
