It replaces OEM part numbers EB575152VU and EB575152VA. Swap it in when the original cell no longer holds voltage through a full day of normal use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGalaxy S \/ SPH-D700 platform fit:\u003c\/strong\u003e\n    The Epic 4G and SPH-D700 share the same battery bay geometry, connector pinout, and BMS handshake logic, so one cell covers all three variants without adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell in an SPH-D700 through charge, idle, and active screen-on cycles. The BMS accepted the charge handshake on the first connection and held voltage within spec through full draw cycles without a cutoff event.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge down to auto-shutdown, then charge to 100% uninterrupted. This gives the fuel gauge IC a clean reference curve for the new cell before the OS starts reporting percentage data.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SPH-D700 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Galaxy S uses a coulomb-counter-based fuel gauge IC that builds its percentage model from learned charge and discharge curves. When you install a new cell, that learned model still references the old, degraded cell's curve. The IC will read the new cell's higher voltage at a given state of charge as a different percentage point than it actually is. One full uninterrupted discharge-to-shutdown followed by a full charge resets the reference baseline and brings percentage reporting back into accurate range.\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 is a voltage cliff, not a capacity fault. Under modem radio or screen peak load, the cell voltage drops sharply at around 3.5–3.6V if the fuel gauge IC has not yet calibrated to the new discharge curve. The OS reads the pre-load resting voltage as 20–30% remaining, but the loaded voltage drops below the BMS cutoff threshold instantly. Run one full calibration cycle first — charge to 4.2V, discharge to auto-shutdown — and the shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405102481498,"sku":"BWCS-SMD700XL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405102514266,"sku":"BWCS-SMD700XL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405102547034,"sku":"BWCS-SMD700XL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMD700XL-1.webp?v=1779369970","url":"https:\/\/batteryweb.com\/products\/sprint-galaxy-s-replacement-battery-37v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
