It fits directly behind the rear cover without any modification. Capacity matches the factory specification at 5.55Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGT-I8262D, SCH-i829, and Duos variants:\u003c\/strong\u003e\n    All listed models share the same battery bay dimensions, connector pitch, and BMS handshake protocol. The EB425365LU part number covers the full group — no variant-specific wiring differences exist between them.\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-I8262D platform. The BMS accepted charge input without fault flags, and the protection circuit triggered correctly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-to-charge cycle. The Galaxy Core's fuel gauge IC is calibrated to the old cell's discharge curve. One full cycle lets it map the new cell before reporting accurate percentages.\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 GT-I8262D after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Galaxy Core's fuel gauge IC stores a discharge curve from the previous cell. When a new cell goes in, the stored curve no longer matches the actual voltage profile of the replacement. The phone reads 25% remaining but the real cell voltage has already dropped below the minimum load threshold — typically around 3.5V under screen or modem draw. The fix is one full uninterrupted discharge to auto-shutdown, then a full charge to 100% before resuming normal use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage. If the voltage drops below approximately 2.5V per cell, the BMS enters lockout mode and blocks charge input to prevent damage. The phone will show nothing — no charging animation, no response. Connect to a wall charger rated at 5V\/1A and leave it for 20–30 minutes before attempting to power on. USB ports on laptops often lack the current to pull the cell out of BMS lockout — use a wall adapter.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404331122778,"sku":"BWCS-SMI829SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404331155546,"sku":"BWCS-SMI829SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404331188314,"sku":"BWCS-SMI829SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMI829SL-1.webp?v=1779369779","url":"https:\/\/batteryweb.com\/products\/samsung-gt-i8262d-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
