It replaces a degraded or failed original cell when the phone can no longer hold charge through a normal day. OEM part numbers EB-L1G6LVA, EB-L1G6LLK, EB-L1G6LLA, and EB585158LP all cross-reference to this same cell format.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGT-i9300T and S III variant fit:\u003c\/strong\u003e\n    The GT-i9300T shares the same battery bay dimensions, connector polarity, and BMS contact layout as the broader Galaxy S III lineup. All listed variants use the same 63.00 × 50.40 × 5.40mm footprint — no modification to the chassis or contacts needed.\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 GT-i9300T hardware. The BMS accepted charge handshake without fault codes, and the protection circuit triggered correctly at low-voltage cutoff — no runaway, no false full-charge termination.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    On first use after fitting this cell, run one full discharge down to automatic shutoff, then charge uninterrupted to 100% without fast charging enabled. The Galaxy S III's fuel gauge IC was calibrated to your old cell's curve — skipping this step causes the percentage counter to read incorrectly for weeks.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-p\"\u003eSudden shutdown at 20–30% on the Galaxy S III after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Galaxy S III uses a coulomb-counter-based fuel gauge that learns the discharge curve of the installed cell over time. When a new cell goes in, the counter is still mapped to the old cell's voltage-versus-capacity curve. Under high-current load — active LTE, GPS, or screen-on gaming — the new cell's voltage can drop sharply below what the old curve predicted, triggering emergency shutdown before the gauge reaches zero. This is a calibration gap, not a defective cell. One complete discharge-to-shutoff followed by a full uninterrupted charge corrects the coulomb counter's baseline. After two full cycles, shutdowns at 20–30% should stop entirely.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone stays warm near the battery compartment during the first few charges\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell starts with higher internal impedance than a cell that has completed several charge cycles. The Galaxy S III's charge IC pushes current into this higher-impedance cell, and the extra resistance converts some of that energy to heat. This is normal for the first two to three charge cycles and not a sign of a faulty cell or charger fault. Warmth near the battery cover — not the screen or processor area — during charging is the expected location. If the phone becomes hot to hold or shows a temperature warning on screen, stop charging and check that the replacement cell is seated flat with no debris under the contacts.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404327288922,"sku":"BWCS-SMI535XL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404327321690,"sku":"BWCS-SMI535XL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404327354458,"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\/telstra-galaxy-s-iii-replacement-battery-38v-2100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
