It replaces the original battery when the existing cell no longer holds a usable charge. Physical dimensions are 46.47 × 39.79 × 5.33mm — confirm these against your current cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eC2030 fitment:\u003c\/strong\u003e\n    The Classic C2030 uses a small-format removable Li-ion cell at 3.7V nominal. This replacement matches the voltage rail and connector orientation the phone's charge IC expects. A mismatch in either drops the device to a boot loop or prevents charging entirely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge and discharge cycles on this cell and monitored BMS cutoff behaviour at both ends of the voltage curve. The protection circuit trips correctly at the low-voltage threshold, and the cell accepts a full charge without thermal spike.\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 for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate its discharge curve against the new cell before any high-current charging pushes current into an uncalibrated state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the C2030 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe C2030 uses a fuel gauge IC that builds a discharge model from the previous cell's history. When you install a new cell, the IC still references the old curve, so the percentage readout drifts — often reading high then dropping suddenly. This is not a fault in the new battery. One full discharge to auto-off followed by an uninterrupted charge to 100% resets the coulomb counter and realigns the reported percentage to the actual cell state.\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 modem or display draws a load spike and the cell voltage drops below the BMS cutoff threshold — even though the gauge still shows charge remaining. It points to an uncalibrated fuel gauge reading optimistically against a fresh cell. Run one full discharge-charge cycle without interruption. After calibration, the gauge tracks the actual voltage curve more accurately and the premature cutoffs stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404298911834,"sku":"BWCS-EAC145XL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404298944602,"sku":"BWCS-EAC145XL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404298977370,"sku":"BWCS-EAC145XL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EAC145XL-1.webp?v=1779369642","url":"https:\/\/batteryweb.com\/products\/auro-classic-c2030-replacement-battery-37v-900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
