It replaces OEM part numbers EB-L1G6LLUC, EB-L1G6LVA, EB-L1G6LLK, EB-L1G6LLA, and EB585158LP. It powers the S3's processor, display, radios, and all background services.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSPH-L710 and Galaxy S3 compatibility:\u003c\/strong\u003e\n    The SPH-L710 is Sprint's Galaxy S3 variant. It uses the same battery bay dimensions (63.00 × 50.40 × 5.40mm), the same 3.8V nominal voltage rail, and the same connector pinout as the international GT-I9300. All listed OEM part numbers cross-reference to this same physical cell.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We seated this cell in an SPH-L710 and cycled it through a full discharge and recharge. The BMS accepted charge current without error, the protection circuit tripped correctly at low-voltage threshold, and the device booted cleanly at each stage of the test.\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-charge cycle at standard current. The S3's fuel gauge IC was calibrated to your old cell's discharge curve. One full cycle at low current lets it remap to the new cell before high-current charging begins.\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 a replacement Galaxy S3 cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Galaxy S3's fuel gauge IC stores a learned discharge curve from the original cell. When you swap in a new cell, that stored curve no longer matches the actual voltage-versus-capacity profile of the replacement. Under load — LTE radio, screen at full brightness, or a background sync burst — the cell voltage drops sharply at a point the gauge still reads as 25%. The phone interprets this voltage cliff as a critical low and shuts down. One full discharge cycle from 100% to automatic power-off, followed by a full charge, forces the coulomb counter to resync to the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If this cell sat unused long enough to drop below approximately 2.5V per cell, the BMS enters lockout to prevent damage — the phone will show nothing when you press power. Connect the phone to a wall charger, not a USB port, and leave it for 15–20 minutes without pressing anything. The charge IC delivers a trickle current to bring the cell voltage above the BMS re-enable threshold, typically around 2.9V, after which normal charging resumes and the phone will boot.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404327387226,"sku":"BWCS-SMI535XL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404327419994,"sku":"BWCS-SMI535XL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404327452762,"sku":"BWCS-SMI535XL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMI535XL-1.webp?v=1779369778","url":"https:\/\/batteryweb.com\/products\/sprint-galaxy-s3-replacement-battery-38v-2100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
