It fits the Samsung GT-C3350, Xcover C3350, and Solid Xcover candybar phones. The cell measures 46.50 × 33.70 × 7.50mm and drops into the original battery compartment using the stock connector.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGT-C3350 and Xcover Solid platform:\u003c\/strong\u003e\n    All three listed models run the same 3.7V battery rail with identical connector pinout and BMS handshake logic, which is why one cell covers the full range. The AB803443BU part number confirms cross-model compatibility at the OEM level.\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 GT-C3350 platform. The BMS accepted the cell without error, charge termination triggered correctly at full capacity, and the protection circuit responded normally to low-voltage cutoff conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After installing a new cell, run one full discharge to automatic power-off, then charge uninterrupted to 100% before resuming normal use. The GT-C3350 fuel gauge IC calibrates its coulomb counter against this first full cycle — skipping it causes the phone to report inaccurate percentages from day one.\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-C3350 after cell replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GT-C3350 fuel gauge IC stores a discharge curve calibrated to the old, degraded cell. When a fresh cell with a steeper voltage curve is installed, the IC misreads remaining capacity and triggers shutdown well before the cell is actually depleted. The voltage drop under screen or radio load hits the cutoff threshold faster than the gauge expects. One full discharge-to-shutdown followed by an uninterrupted charge to 100% forces the IC to rebuild its reference curve against the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone feels warm near the battery compartment on the first few charges\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell has higher internal impedance than a broken-in cell. In the first two to three charge cycles, the charge IC pushes current into a cell that resists it slightly more than normal, generating mild heat at the battery interface. This is a temporary condition and reduces as the cell cycles. If the phone feels hot — not just warm — above 45°C, stop the charge and check that the contacts are seated flat against the cell terminals with no gap.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405016531034,"sku":"BWCS-SMC335SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405016563802,"sku":"BWCS-SMC335SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405016596570,"sku":"BWCS-SMC335SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMC335SL-1.webp?v=1779369858","url":"https:\/\/batteryweb.com\/products\/samsung-gt-c3350-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
