It fits the same footprint at 50.60 × 35.69 × 6.08mm and connects directly to the device's internal battery circuit. Swap it in when the original cell no longer holds a usable charge between drives.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRoadMate 3030 and 3030-LM compatibility:\u003c\/strong\u003e\n    Both models run the same 3.7V single-cell architecture with an identical connector and physical envelope. One cell covers both variants — no wiring changes, no adapter required.\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 RoadMate platform. The BMS held the 3.7V nominal rail cleanly, accepted a full charge without triggering protection cutoff, and discharged at the low draw typical of a GPS receiver and LCD backlight.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after fitting:\u003c\/strong\u003e\n    After fitting this cell, power the unit on outdoors and leave it stationary. The RoadMate performs a cold start after any full power interruption — first satellite fix takes 5–10 minutes versus under a minute on subsequent warm starts. Let it complete that initial lock before driving.\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 battery level drops below threshold\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe RoadMate 3030 reduces GPS receiver sensitivity at low battery to extend remaining charge. This drops position accuracy — the unit may show your location drifting or jumping to the nearest road rather than tracking your actual path. It's a firmware-level power conservation behaviour, not a hardware fault. Keep the cell above 3.5V during active navigation to maintain full receiver sensitivity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRoadMate shuts off mid-route without a low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a battery replacement, the RoadMate's charge indicator is uncalibrated to the new cell's discharge curve. The device reads remaining capacity inaccurately and hits its voltage cutoff threshold before the on-screen warning fires. Run two to three full charge and discharge cycles on the new cell. The indicator recalibrates progressively and the warning will appear at the correct point — typically when cell voltage reaches approximately 3.4V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377640112218,"sku":"BWCS-MR3030SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377640144986,"sku":"BWCS-MR3030SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377640177754,"sku":"BWCS-MR3030SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MR3030SL-1.webp?v=1778771767","url":"https:\/\/batteryweb.com\/products\/magellan-roadmate-3030-replacement-battery-37v-750mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
