It fits the GT-N7100, GT-N7105, and Galaxy Note II LTE 32GB among other Note II variants. Swap it when the original cell no longer holds enough charge to carry the device through a normal day.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGT-N7100 and GT-N7105 compatibility:\u003c\/strong\u003e\n    Both models use the same 3.8V rail, identical connector footprint, and share the EB595675LU part number — the BMS handshake and charge termination logic are the same across the full Note II family.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on a GT-N7100. The BMS accepted charge termination correctly, held cutoff above 3.0V under load, and passed over-temperature protection thresholds without event.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-charge cycle to the end. This gives the fuel gauge IC time to map the new cell's discharge curve before high-current charging pushes current into an uncalibrated 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 GT-N7100 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Galaxy Note II uses a coulomb counter in the fuel gauge IC to track charge state. When a new cell goes in, the IC still holds calibration data from the old, degraded cell. The percentage shown on screen reflects that stale curve — not the actual state of the new cell. One full discharge to shutdown followed by an uninterrupted charge to 100% resets the coulomb counter to the new cell's actual capacity.\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 fuel gauge IC has not yet calibrated to the new cell's voltage-versus-capacity curve. The phone reads 25% but the cell's actual open-circuit voltage drops below the modem or display load threshold — triggering an emergency shutdown. It is not a faulty cell. Force a full discharge until the phone powers off on its own, then charge to 100% without interruption. After that cycle, the IC maps the correct low-voltage cliff and shutdowns at false percentages stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404347899994,"sku":"BWCS-SMN710XL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404347932762,"sku":"BWCS-SMN710XL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404347965530,"sku":"BWCS-SMN710XL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMN710XL-1.webp?v=1779369820","url":"https:\/\/batteryweb.com\/products\/samsung-gt-n7100-replacement-battery-38v-3100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
