It fits directly into the removable battery bay and connects to the same three-contact puck used by the original Samsung cell. When the stock battery can no longer sustain voltage under screen or modem load, this cell restores full function.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSCH-I415 battery bay compatibility:\u003c\/strong\u003e\n    All Stratosphere II variants share the same chassis dimensions and three-pad contact layout. The cell measures 69.80 × 51.90 × 4.20mm — matching the original bay tolerances so no adapter or modification is needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge-discharge cycle on an SCH-I415 unit. The BMS accepted charge from the stock charging circuit without fault codes, and the protection circuit tripped correctly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After installing this cell, disable fast charging and run one complete discharge down to automatic shutdown, then charge to 100% uninterrupted. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current charging begins.\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 Stratosphere II after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell has a slightly different discharge curve than the aged cell the fuel gauge IC was calibrated against. When the phone hits a voltage point it was trained to treat as 20–30%, the new cell may actually be at a steeper voltage cliff — and the modem's transmit burst pulls enough current to drop voltage below the BMS cutoff threshold. The phone shuts down not because the cell is empty, but because instantaneous voltage sag trips the protection circuit. One full discharge-charge cycle recalibrates the coulomb counter and eliminates most of these premature shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery compartment during first few charges\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh cell starts with higher internal impedance than a cycled one. During the first two or three charge cycles, the charge IC pushes current into that higher-impedance cell, which converts more energy to heat than usual. This is normal and fades as the cell breaks in. If warmth persists past the third full charge cycle or the phone becomes hot to the touch, check that the battery contacts are clean and fully seated — a partial contact forces higher resistance at the pad, which compounds the heat.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404338200666,"sku":"BWCS-SMT699XL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404338233434,"sku":"BWCS-SMT699XL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404338266202,"sku":"BWCS-SMT699XL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMT699XL-1.webp?v=1779369779","url":"https:\/\/batteryweb.com\/products\/verizon-galaxy-stratosphere-ii-4g-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
