It matches the OEM part numbers 338937010172 and T300-3. Fit the cell when the unit no longer holds charge through a typical drive or shuts off before the indicator reaches empty.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMoov 400 and 405 platform:\u003c\/strong\u003e\n    These models share the same battery bay dimensions (50 × 37 × 6mm), connector pinout, and 3.7V charge rail. The BMS on each unit reads the same charge profile, so no firmware workaround is needed when swapping cells across this group.\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 Mio Moov 400 unit. The BMS accepted charge without fault flags, balanced correctly at 4.2V, and held cutoff voltage at the expected 3.0V threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after swap:\u003c\/strong\u003e\n    After fitting this cell, power the GPS on outdoors before driving. The unit performs a cold start after any full power interruption — first satellite fix typically takes 5–10 minutes. Subsequent warm starts run under a minute once the almanac is 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 reduced at low battery on the Mio Moov 400\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Mio Moov 400 scales back receiver sensitivity as cell voltage drops toward the 3.0V cutoff. This is a firmware-level power saving measure — the GPS chip draws less current by narrowing its signal search window. The result is degraded position accuracy and slower route recalculation on low charge. Keep the unit above 50% charge during active navigation to avoid this behaviour.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUnit shuts off without warning before the battery indicator hits empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a full power removal, the Mio Moov 400 loses its calibrated voltage-to-percentage mapping. The fuel gauge defaults to a generic discharge curve that does not match the actual cell. The unit then hits the BMS cutoff voltage — 3.0V — before the on-screen indicator reaches one bar. Run two full charge and discharge cycles after fitting the new cell to let the device recalibrate its threshold readings.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377680187482,"sku":"BWCS-MIV400SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377680220250,"sku":"BWCS-MIV400SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377680253018,"sku":"BWCS-MIV400SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MIV400SL-1.webp?v=1778771881","url":"https:\/\/batteryweb.com\/products\/mitac-mio-moov-400-replacement-battery-37v-750mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
