It fits the original battery bay and connects via the same three-contact interface. OEM part numbers AB653850CE, AB653850CU, and AB653850EZ all cross to this cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGT-I7500 and GT-I7500H fit:\u003c\/strong\u003e\n    Both variants use the same 3.7V cell with the same contact layout and BMS handshake. The H suffix denotes a regional hardware revision — the battery is mechanically and electrically identical across both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full discharge and charge on the GT-I7500 platform. The BMS accepted charge from the device's native charge IC without tripping overcurrent protection, and voltage held stable through the mid-cycle range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installing this cell, run one complete discharge down to automatic shutoff, then charge uninterrupted to 100%. The GT-I7500's fuel gauge IC was calibrated to the original cell's discharge curve — one full cycle resets it against the new cell before you rely on the percentage reading.\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-I7500\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe GT-I7500's ageing fuel gauge IC holds a discharge curve from the original 2008 cell. A new cell with different internal impedance hits a voltage cliff at a different state of charge than the IC expects. When the GSM radio or screen draws a short current spike, the cell voltage drops below the BMS cutoff threshold before the percentage display reaches zero. One full discharge-to-shutoff cycle followed by an uninterrupted charge teaches the coulomb counter where the real floor is. After that cycle, the shutoffs at false percentages stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePercentage reading jumps or reads 0% immediately after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe GT-I7500 stores the previous cell's learned capacity data in the fuel gauge IC — it does not automatically reset when a new battery is installed. If the phone displays 0%, jumps from 15% to 60%, or drains the percentage bar faster than the charge level actually warrants, the IC is comparing the new cell against stale reference data. Power the phone off, leave the new battery installed for 10 minutes, then power on and run a full discharge cycle to shutoff before recharging. Recheck the percentage behaviour after that single cycle — it should stabilise at 3.7V nominal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405135446106,"sku":"BWCS-SMI750XL-1","price":27.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43405135478874,"sku":"BWCS-SMI750XL-2","price":31.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43405135511642,"sku":"BWCS-SMI750XL-3","price":34.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMI750XL-big.webp?v=1779370279","url":"https:\/\/batteryweb.com\/products\/samsung-gt-i7500-replacement-battery-37v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
