Direct replacement for Magellan RoadMate units

This 3.7V 720mAh lithium-ion cell matches the original MR2045 part number and fits RoadMate 2045, 2055, 2120T, 2136T-LM and 2145T-LM models. The pack measures 50.98 x 36.44 x 5.60mm and weighs 50.0g, matching the factory footprint exactly. Supplied as a single black unit in new condition.

Check your current battery label and connector

Verify that the existing pack carries the MR2045 code and that the connector orientation matches the photographs. Confirm the device powers on and charges normally before disassembly, as a faulty charging circuit will damage the new cell. Ensure you have the small tools needed to open the GPS casing safely.

Replaces an exhausted or swollen OEM pack

The upgrade is worthwhile when the original battery no longer holds a charge, shows physical swelling or causes the unit to shut down unexpectedly. It restores the original runtime without adding capacity beyond the 720mAh rating. Buyers needing longer operating time between charges or a higher-voltage chemistry will not be served by this direct-fit replacement.
