It fits all three variant model codes: SCH-I605, SCHI605TSV, and SCHI605ZWV. The cell dimensions are 75.20 × 55.40 × 5.80mm — matching the original tray without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSCH-I605 variant compatibility:\u003c\/strong\u003e\n    The TSV and ZWV suffix variants share the same battery tray dimensions and voltage rail as the base SCH-I605. All three use the same connector pinout and BMS handshake, so one cell covers the full Verizon Note II lineup without any hardware changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a Note II unit, confirming the BMS accepted the charge handshake on the first connect. The protection circuit responded correctly to both low-voltage cutoff and over-current conditions during the test discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installation, disable fast charging and run one complete discharge-to-charge cycle at standard rate. This gives the fuel gauge IC time to map the new cell's discharge curve before high-current charging pushes current into 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\"\u003eWhy the SCH-I605 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Note II uses a coulomb counter that builds its model of the cell incrementally over several charge cycles. When you swap the physical cell, the IC still holds the old cell's capacity curve in memory. The percentage readout reflects that stale curve, not the new cell's actual state of charge. One full discharge below 10% followed by a complete charge to 100% forces the IC to reset and relearn the new cell's parameters.\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 is a voltage cliff, not a capacity problem. Under modem or display load, the cell's internal resistance causes voltage to sag below the BMS cutoff threshold even though the reported percentage reads mid-range. The fuel gauge IC hasn't yet correlated that voltage drop to the correct state-of-charge point on the new cell. Run two full calibration cycles and monitor shutdown voltage — it should stabilise above 3.4V under load once the IC has accurate data.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404348096602,"sku":"BWCS-SMN710SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404348129370,"sku":"BWCS-SMN710SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404348162138,"sku":"BWCS-SMN710SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMN710SL-1.webp?v=1779369820","url":"https:\/\/batteryweb.com\/products\/verizon-sch-i605-replacement-battery-37v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
