Compatible Garmin ZUMO models

This replacement battery fits the Garmin ZUMO 340LM, 350LM and 390LM motorcycle navigators. It matches the original Garmin part number 361-00059-00 and is built to the same 50.10 x 34.00 x 9.90 mm form factor. Riders needing a direct swap for a depleted cell will find it a straightforward fit. The black lithium-polymer pack is supplied new and ready to install.

Check your device and connector

Verify that your unit is one of the three ZUMO models listed above before ordering. Confirm the existing battery carries the 361-00059-00 part number printed on its label. Ensure you are comfortable opening the navigator’s case and disconnecting the original pack, as no installation tools or instructions are included. The replacement uses the same two-wire connector and 3.7 V nominal voltage.

Runtime on long rides

The 1800 mAh lithium-polymer cell stores 6.66 Wh of energy, supporting extended navigation sessions between charges. Li-Polymer chemistry maintains a stable voltage curve during continuous GPS reception and screen use. Capacity fade is gradual over hundreds of charge cycles rather than sudden after a few deep discharges. The pack operates within the same temperature range as the original battery.
