It matches the original 338040000014 part number and fits the same 50.55 × 36.39 × 5.73mm footprint. Swap it in when the unit no longer holds a charge or shuts off during navigation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRoadMate 2230 and 2230T-LM fit:\u003c\/strong\u003e\n    Both variants share the same internal battery bay, connector pinout, and charge circuit. One cell covers both.\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 protection circuit triggered correctly at low-voltage cutoff and accepted a full charge without fault flags from the device.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst fix after power interruption:\u003c\/strong\u003e\n    After fitting this cell, power the unit on outdoors before driving. A cold start — triggered any time the GPS loses all power — can take 5–10 minutes to acquire a satellite fix. Subsequent warm starts drop back under a minute once the almanac data is rebuilt.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the RoadMate 2230 shuts off without a low-battery warning\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe RoadMate 2230 reads remaining charge by measuring cell voltage. After years of cycling, the original cell's voltage curve flattens — the unit reports adequate charge right up until voltage collapses past the cutoff threshold. The on-screen battery indicator never catches up, so the device just switches off. A fresh cell restores a predictable voltage curve, and the indicator behaves as expected again.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGPS accuracy drops during active navigation at low battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAt low cell voltage, the RoadMate reduces power to the GPS receiver module to protect the remaining charge. Lower receiver power means weaker satellite signal processing, which degrades position accuracy — you may notice the cursor drifting or lag in turn-by-turn updates. This is not a software fault. Keep the cell above 3.6V during active use to maintain full receiver sensitivity. Charging via the vehicle adapter while navigating is the most direct fix.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377620910170,"sku":"BWCS-MR2230SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377620942938,"sku":"BWCS-MR2230SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377620975706,"sku":"BWCS-MR2230SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MR2230SL-1.webp?v=1778771746","url":"https:\/\/batteryweb.com\/products\/magellan-roadmate-2230-replacement-battery-37v-750mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
