It restores power to the internal battery that runs the GPS receiver, display, and onboard map storage. Capacity is 1800mAh (6.66Wh) — matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCrossover and 2500T compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, connector pinout, and 3.7V nominal voltage rail. The BMS handshake is identical across the two, so one cell covers both 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 the Crossover platform. The BMS accepted the cell without error flags, and the charge circuit terminated correctly at full capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-fix satellite acquisition after installation:\u003c\/strong\u003e\n    After fitting this cell, power the GPS on outdoors and let it run until it acquires a satellite fix before driving. The device performs a cold start after any full power interruption — first 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\"\u003eWhy the Crossover shuts off without showing a low-battery warning\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Crossover reads state-of-charge from a voltage curve calibrated to the original cell. When a degraded original battery is replaced, the firmware's voltage-to-percentage mapping may be out of sync with the new cell until it completes one full charge cycle. The device can hit its hardware cutoff threshold — typically around 3.0V under load — before the on-screen indicator reaches the warning zone. Run one full charge from flat to 100% after installation to let the display track the actual charge curve accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSaved routes and POIs missing after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the Crossover, some user-saved routes and points of interest are held in battery-backed RAM rather than written permanently to flash. Removing the battery cuts power to that memory, and those records are lost. Base map data and pre-loaded POI databases survive because they sit on flash storage. Before swapping the battery, export any custom routes via the USB connection to a PC — that is the only way to recover them after a full power removal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377661968474,"sku":"BWCS-MRC001SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377662001242,"sku":"BWCS-MRC001SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377662034010,"sku":"BWCS-MRC001SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MRC001SL-1.webp?v=1778771818","url":"https:\/\/batteryweb.com\/products\/magellan-crossover-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
