It replaces the original EB575152VU after years of charge cycling have degraded the cell's capacity. Dimensions are 51.00 × 50.50 × 5.50mm — same footprint as the OEM unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGT-i9000 series compatibility:\u003c\/strong\u003e\n    The GT-i9000, SGH-i897, and Vibrant share the same battery bay dimensions, connector pinout, and charge IC handshake. All of them accept the EB575152VU cell without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the GT-i9000. The BMS accepted the charge IC handshake correctly, hit full charge cutoff at 4.2V, and held voltage under screen-on load without tripping low-voltage protection early.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first installation, run one full discharge to automatic shutdown, then charge uninterrupted to 100%. This gives the phone's fuel gauge IC a clean reference curve against the new cell — skipping it leaves the coulomb counter tracking stale data from the old degraded cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the GT-i9000 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GT-i9000 uses a fuel gauge IC that builds its charge estimate from the discharge curve of the cell it was calibrated against. Swap in a new cell and the IC is still referencing the old curve — which was shaped by years of capacity fade. The percentage shown on screen can read 40% while the actual cell state is already below the modem's minimum sustain voltage. One complete discharge-to-shutdown followed by an uninterrupted charge cycle resets the coulomb counter to the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't recalibrated and the cell hits a voltage cliff under load — typically when the modem fires a transmission burst or the screen backlight peaks. The reported percentage looks safe, but cell voltage drops below 3.4V under that instantaneous draw, tripping the BMS protection circuit. It's not a faulty battery. Complete one full discharge-charge cycle, then confirm resting voltage sits above 3.7V before putting the phone back into normal use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405118832730,"sku":"BWCS-SMG900SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405118865498,"sku":"BWCS-SMG900SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405118898266,"sku":"BWCS-SMG900SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMG900SL-1.webp?v=1779370243","url":"https:\/\/batteryweb.com\/products\/samsung-gt-i9000-replacement-battery-37v-1250mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
