It replaces OEM part number BL-N5000C and restores power to phones where the original cell has degraded or failed. Capacity is 5000mAh (19Wh) — identical to the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGN5002 and M5 Enjoy fitment:\u003c\/strong\u003e\n    Both devices run the same 3.8V battery rail, share the same physical footprint (93.10 × 63.30 × 4.80 mm), and use the same BL-N5000C connector and BMS handshake. One cell fits both 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, discharge, and modem-load draw on the GN5002. The BMS held stable voltage across the full discharge curve with no mid-cycle cutoff or over-temperature trip.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, disable fast charging and run one full discharge-to-charge cycle at standard rate. This lets the fuel gauge IC map its coulomb counter against the new cell's discharge curve before high-current charging begins on 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 GN5002 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still running the discharge curve from the old, degraded cell. The new cell has a steeper voltage drop near the end of discharge — the phone's power IC sees the voltage fall below its cutoff threshold before the reported percentage catches up. It reads 25% but the actual cell voltage has already crossed the shutdown floor. One full slow-charge cycle forces the coulomb counter to resync against the new curve and eliminates the premature cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB fast charge not activating after replacement on the M5 Enjoy\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn first connection after a cell swap, the charge IC may not negotiate the fast-charge protocol because the BMS on the new cell starts in a conservative initialisation state. This is not a fault — it resolves after the first complete charge cycle at standard current. Plug into a standard 5V\/1A charger, let it charge fully to 100%, then disconnect. Fast charge negotiation should resume normally on the next session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392087687258,"sku":"BWCS-GNN500SL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392087720026,"sku":"BWCS-GNN500SL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392087752794,"sku":"BWCS-GNN500SL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GNN500SL-1.webp?v=1779143685","url":"https:\/\/batteryweb.com\/products\/gionee-gn5002-replacement-battery-38v-5000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
