It also fits the MT-9081W, SH26160Mobistel\/STD, and SH26162Mobistel\/STD variants. All share the same connector, voltage rail, and BMS handshake protocol.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCynus T2 platform fit:\u003c\/strong\u003e\n    The Cynus T2, MT-9081W, and SH26160\/SH26162 variants run the same 3.7V battery architecture with a shared connector pinout and fuel gauge communication line. One cell fits all listed models 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 Cynus T2 hardware. The BMS accepted the full charge sequence without triggering protection cutoff, and the fuel gauge IC registered capacity correctly after one complete cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one full discharge-to-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging begins on an uncalibrated cell.\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 Cynus T2 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Cynus T2's fuel gauge IC retains the discharge curve from the old, degraded cell. When a new cell is installed, the IC misreads the actual remaining voltage and triggers a low-voltage shutdown earlier than expected. This typically shows as an abrupt power-off at 20–30% while the modem or display is under load. One full discharge cycle — draining to auto-shutdown, then charging uninterrupted to 100% — resets the coulomb counter against the new cell's curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery during the first few charging sessions\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell starts with slightly higher internal impedance than a broken-in cell. During initial charging, the charge IC pushes current into that higher resistance, generating more heat than normal. This is not a fault — it settles after two or three full cycles as internal impedance drops. If the phone stays consistently warm beyond the third full charge, check that the charger output does not exceed 5V\/1A for this device.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404323061850,"sku":"BWCS-MCT200XL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404323094618,"sku":"BWCS-MCT200XL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404323127386,"sku":"BWCS-MCT200XL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MCT200XL-1.webp?v=1779369761","url":"https:\/\/batteryweb.com\/products\/mobistel-cynus-t2-replacement-battery-37v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
