It matches the OEM voltage rail and connector layout used across this device family. Capacity is rated at 6.29Wh — identical to the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMio P-series compatibility:\u003c\/strong\u003e\n    The P350, P510, and P550 share the same battery bay dimensions (50 × 35 × 7mm), connector pinout, and 3.7V nominal voltage rail. One cell covers the full lineup because Mitac used a common power platform across these GPS units.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a Mio P550. The BMS accepted charge from the OEM cradle without fault flags, held voltage above 3.5V through a full navigation session, and hit the low-battery cutoff at the expected threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after fitting:\u003c\/strong\u003e\n    After fitting this battery and powering on, take the device outdoors before first use. A full power interruption forces a GPS cold start — first satellite fix can take 5 to 10 minutes. Subsequent warm starts drop back under a minute once almanac data is re-cached.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGPS accuracy dropping at low battery on the Mio P350\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome Mio units reduce receiver sensitivity when battery voltage sags below roughly 3.55V. The GPS chipset pulls back power to the RF front end to stay within the available current budget. The result is fewer satellites tracked and wider position error — sometimes 20 to 50 metres off course. Keeping the cell above that voltage threshold, either via the vehicle cradle or a timely charge, keeps the receiver running at full sensitivity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice shutting off without low-battery warning on the Mio P550\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a battery swap, the fuel gauge IC on the Mio P550 has no calibration data for the new cell. It estimates state-of-charge from a lookup table built around the degraded original cell, so the percentage readout runs optimistic. The unit hits the hardware cutoff voltage before the software warning fires. To recalibrate, run the device on active navigation until it shuts itself off, then charge uninterrupted to 100% — one full cycle resets the fuel gauge baseline.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377729241178,"sku":"BWCS-MIOP350XL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377729273946,"sku":"BWCS-MIOP350XL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377729306714,"sku":"BWCS-MIOP350XL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MIOP350XL-1.webp?v=1778771880","url":"https:\/\/batteryweb.com\/products\/mitac-mio-p350-replacement-battery-37v-1700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
