It matches the OEM voltage rail and connector, allowing the device to power on and resume navigation without modification. Capacity figure is taken directly from product specification — 4.63Wh total.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMio C220 series compatibility:\u003c\/strong\u003e\n    The C220, C220s, C230, and C250 share the same battery bay dimensions and 3.7V single-cell architecture. The connector orientation and BMS handshake protocol are identical across these models, so one cell fits all four without adapters or firmware changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on a Mio C220 unit. The BMS accepted charge from the OEM cradle charger without fault, held voltage above the low-battery threshold through a full navigation session, and tripped cutoff cleanly at the correct floor voltage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after fitting:\u003c\/strong\u003e\n    After any full power interruption, the Mio C220 performs a cold start — the GPS receiver has lost its ephemeris data and must reacquire satellite positions from scratch. Power the device on outdoors with a clear sky view and allow 5–10 minutes for first fix before driving. Subsequent warm starts will lock in under a minute.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSaved routes and POIs disappearing after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Mio C220 stores some navigation data — including recent destinations and certain route caches — in volatile RAM backed by the main battery. When the battery is fully removed, that RAM loses power and the data clears. Saved favourites stored in flash memory survive the swap, but recently calculated routes and unsaved POIs typically do not. Before removing the old battery, export any routes you want to keep via the device's save function or note the destinations manually.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMio C220 shutting off without a low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe on-screen battery indicator on the C220 is calibrated against the original cell's discharge curve. A new cell — or one that has aged differently — can cause the indicator to read incorrectly, showing two bars right up until the device cuts off. The BMS enforces a hard voltage floor around 3.0V per cell regardless of what the indicator shows. To recalibrate, run two full charge-to-cutoff cycles without interruption so the device can relearn the actual discharge curve of the new cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377718100058,"sku":"BWCS-MIOC220SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377718132826,"sku":"BWCS-MIOC220SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377718165594,"sku":"BWCS-MIOC220SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MIOC220SL_1.webp?v=1778771880","url":"https:\/\/batteryweb.com\/products\/mitac-mio-c220-replacement-battery-37v-1250mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
