It slots into the original battery bay and connects to the same three-contact interface used on both models. Use this when the original cell no longer holds a usable charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSCH-2200 and SGH-600 compatibility:\u003c\/strong\u003e\n    Both models share the same 3.7V battery bay, contact pitch, and charge management circuit. One replacement cell covers either handset without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the SCH-2200 platform. The phone's charge IC accepted the new cell without fault flags, and the BMS responded correctly to termination at full voltage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\u003c\/strong\u003e\n    On first use after swapping cells, disable any fast-charge mode and run one full discharge down to automatic cutoff, then charge to 100% uninterrupted. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging begins on an uncalibrated state-of-charge register.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SCH-2200 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe phone's fuel gauge IC stores a learned discharge curve from the original cell. When a new cell goes in, that stored curve no longer matches the actual voltage-to-capacity relationship of the replacement. The gauge reads voltage but maps it to the old profile, so it shows percentages that drift from reality. One full uninterrupted discharge-charge cycle forces the IC to rebuild its reference curve against the new cell.\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 cell voltage drops sharply under load — screen-on or active call — while the gauge still shows a comfortable percentage. The protection circuit cuts power the moment cell voltage falls below its low-voltage threshold, typically around 3.0V under load. The gauge percentage at that point is meaningless because it was calibrated to a different discharge curve. Run the recalibration cycle first; if shutdowns continue, check that the battery contacts are clean and seating fully to avoid added resistance pulling voltage down faster.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409455284314,"sku":"BWCS-SMH600SL-1","price":22.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43409455317082,"sku":"BWCS-SMH600SL-2","price":25.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43409455349850,"sku":"BWCS-SMH600SL-3","price":27.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMH600SL-big.webp?v=1779579736","url":"https:\/\/batteryweb.com\/products\/samsung-sch-2200-replacement-battery-37v-1150mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
