It fits the same physical footprint at 89.73 × 60.50 × 3.15mm and connects to the same charge IC on the motherboard. Swap it in when the original cell no longer holds a usable charge between top-ups.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eElife S5.5L and GN9000L fit:\u003c\/strong\u003e\n    Both models run the same 3.8V battery bay, BL-N2450 part number, and connector pinout. The BMS handshake is identical across both, so one cell covers either phone 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 a controlled rig, confirmed BMS communication with the charge IC, and verified cutoff thresholds at both the low-voltage floor and full-charge ceiling before shipping.\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 map its coulomb counter against the new cell's actual discharge curve before any 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 Elife S5.5L after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Elife S5.5L uses a coulomb-counting fuel gauge IC that was calibrated to the discharge curve of the original aged cell. A new cell has a steeper voltage cliff at the lower end of its curve, so the IC underestimates remaining capacity. When the modem or display pulls a high-current burst, cell voltage dips below the BMS cutoff before the OS has time to shut down gracefully. One full discharge-to-shutdown cycle followed by an uninterrupted charge to 100% forces the IC to re-anchor its zero point, and the shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone reports wrong battery percentage after replacing the BL-N2450\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the GN9000L stores a learned capacity model tied to the old cell's internal resistance and voltage curve. Drop in a fresh cell and the stored model no longer matches what the hardware is actually measuring, so percentage readings jump or stall. The fix is a hard recalibration: drain the phone until it powers off on its own, then charge uninterrupted to 100% with fast charging disabled. After that first full cycle, the coulomb counter resets its baseline and percentage readings stabilise.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404153356378,"sku":"BWCS-GNN900SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404153389146,"sku":"BWCS-GNN900SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404153421914,"sku":"BWCS-GNN900SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GNN900SL-1.webp?v=1779369080","url":"https:\/\/batteryweb.com\/products\/gionee-elife-s55l-replacement-battery-38v-2450mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
