It replaces the original power cell when the factory battery can no longer hold a usable charge. Voltage and form factor match the original spec: 53.00 × 33.90 × 5.60mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eChic series cell fitment:\u003c\/strong\u003e\n    These models share a common battery bay size and voltage rail at 3.7V nominal. The connector pinout and physical footprint are consistent across the listed variants, so one cell covers the range 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 a representative unit. The BMS accepted charge correctly, hit full cutoff voltage cleanly, and showed no error flags during the test cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fuel gauge reset:\u003c\/strong\u003e\n    After fitting this cell, disable fast charging and run one full discharge down to automatic shutdown, then charge uninterrupted to 100%. This gives the fuel gauge IC a clean reference curve for the new cell before high-current charging begins.\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 replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity fault. Under load from the modem radio or screen, the cell voltage drops sharply before the fuel gauge IC expects it to. The OS reads 25% but the cell is already sagging below the minimum operating threshold. One full discharge-to-shutdown and uninterrupted recharge cycle recalibrates the coulomb counter and eliminates most of these premature cutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone shows inflated or jumping battery percentage after cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC stores a charge curve mapped to the old cell. When a new cell goes in, that stored model no longer matches actual cell behaviour, so the percentage reading drifts or jumps. The fix is a full calibration cycle: discharge fully until the phone shuts itself off, then charge in one unbroken session to 100% without interruption. After that cycle the IC rewrites its reference model and percentage readings stabilise.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405114212442,"sku":"BWCS-HFC250SL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405114245210,"sku":"BWCS-HFC250SL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405114277978,"sku":"BWCS-HFC250SL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HFC250SL-1.webp?v=1779369992","url":"https:\/\/batteryweb.com\/products\/olympia-chic-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
