It fits the same battery bay and connector as the OEM unit. Capacity is rated at 6.48Wh, matching the original cell's energy spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSCH-LC11 and SCH-I100 Geen platform:\u003c\/strong\u003e\n    Both variants run the same 3.7V nominal voltage rail and share an identical connector footprint and BMS handshake protocol, which is why one cell covers the full model group.\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 SCH-LC11 hardware. The BMS accepted the charge handshake without rejection, and the protection circuit tripped correctly at low-voltage cutoff — no runaway, no false shutdown at full state of charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, run one complete discharge-charge cycle with fast charging disabled. This lets the fuel gauge IC map the new cell's discharge curve before the charge IC pushes higher 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 SCH-LC11 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SCH-LC11's modem and display draw sharp current spikes that expose a steep voltage cliff in any new Li-ion cell before it's been cycled. If the cell voltage drops below the BMS cutoff threshold under that load — even briefly — the phone powers off regardless of the percentage shown on screen. The fuel gauge IC is still reading from its old calibration table, so the displayed percentage is not accurate until the new cell's curve is mapped. Run one full discharge to near-zero, then charge to 100% without interruption to anchor the calibration.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOS reporting wrong battery percentage after installing this cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe coulomb counter inside the SCH-LC11 builds its percentage model against the original cell's capacity and impedance curve. A new 1750mAh cell with different internal impedance throws that model off immediately, producing percentage jumps, stalls at certain levels, or readings that don't match actual remaining charge. This isn't a fault in the replacement cell — it's the fuel gauge IC recalibrating. One full discharge-charge cycle corrects it. If the percentage still behaves erratically after two cycles, check that the battery contacts on the device are clean and making full contact.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404342657114,"sku":"BWCS-SMI520XL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404342689882,"sku":"BWCS-SMI520XL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404342722650,"sku":"BWCS-SMI520XL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMI520XL-1.webp?v=1779369820","url":"https:\/\/batteryweb.com\/products\/uscellular-sch-lc11-replacement-battery-37v-1750mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
