It replaces OEM part numbers EB-L1G6LLUC, EB-L1G6LVA, EB-L1G6LLK, EB-L1G6LLA, and EB585158LP. The cell slots into the removable battery bay and connects to the same spring contacts as the original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGalaxy S 3 and S III compatibility:\u003c\/strong\u003e\n    The S 3 and S III share the same removable battery form factor, connector pitch, and 3.8V nominal voltage rail across all regional variants. The BMS on each variant communicates with the phone's charge IC using the same handshake protocol, so one cell covers the full lineup without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell in a Galaxy S III body and monitored BMS behavior across charge and discharge. The protection circuit tripped correctly at the low-voltage cutoff floor and accepted a full charge cycle without thermal events or charge IC rejection.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    Disable fast charging for the first complete discharge-charge cycle after swapping this cell. The fuel gauge IC is still calibrated to the old cell's discharge curve. One full cycle at standard current lets the coulomb counter reset against 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 the replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC was calibrated to the discharge curve of the old, degraded cell. When the new cell hits a voltage the phone's gauge reads as 20–30%, the actual cell voltage may be dropping faster under modem or display load than the IC expects — and the BMS cuts power to protect the cell. The fix is a full, uninterrupted discharge down to automatic shutdown followed by a complete charge to 100% with the phone off or idle. After one or two of these cycles, the coulomb counter recalibrates and the percentage readout stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone feels warm near the battery during the first few charges\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell has higher internal impedance than a broken-in cell. The charge IC pushes current into that resistance, and some of that energy converts to heat before the cell's impedance drops after a few cycles. This is normal and should reduce noticeably after two or three full charge cycles. If the warmth persists past the third cycle or the phone is hot to the touch, check that the battery contacts are seated flat — a tilted cell increases resistance at the contact points and keeps impedance elevated.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404327157850,"sku":"BWCS-SMI535XL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404327190618,"sku":"BWCS-SMI535XL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404327223386,"sku":"BWCS-SMI535XL-3","price":37.99,"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\/t-mobile-galaxy-s-3-replacement-battery-38v-2100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
