It fits the Maestro 1700 directly, matching the OEM connector and physical footprint. Voltage and capacity align with the original T300-3 specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMaestro 1700 fitment:\u003c\/strong\u003e\n    The Maestro 1700 uses a single-cell Li-ion pack at 3.7V nominal. This cell matches the original connector pinout and physical dimensions — 50.30 x 36.65 x 5.59mm — so it seats correctly in the battery bay 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 bench and confirmed the protection circuit trips correctly at low-voltage cutoff. The BMS holds charge through a standard USB top-up cycle without false termination.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst fix after swap:\u003c\/strong\u003e\n    After fitting this cell, power the Maestro 1700 on outdoors and let it acquire a satellite signal before driving. A cold start after full power removal takes 5–10 minutes for first fix. 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 when the Maestro 1700 battery runs low\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAt low state of charge — typically below 3.5V — some GPS units reduce RF receiver sensitivity to cut power draw. On the Maestro 1700, this can show up as position drift or a weaker satellite signal bar count. The fix is straightforward: keep the cell above the low-battery threshold during active navigation. Plug into the car charger during long routes so the receiver runs at full sensitivity throughout.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMaestro 1700 shuts off without warning before the battery indicator hits zero\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a replacement swap, the fuel gauge software still references the old cell's discharge curve. The device reads remaining charge against a calibrated baseline that no longer matches the new battery. This causes the shut-off threshold to trigger — usually around 3.6V — before the on-screen indicator reaches the final bar. Run two or three full charge and discharge cycles to let the device recalibrate its voltage-to-percentage mapping.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377638277210,"sku":"BWCS-MM1700SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377638309978,"sku":"BWCS-MM1700SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377638342746,"sku":"BWCS-MM1700SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MM1700SL-1.webp?v=1778771767","url":"https:\/\/batteryweb.com\/products\/magellan-maestro-1700-replacement-battery-37v-750mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
