BMW Motorrad Navigator V 7.4V Replacement Battery 361-00063-00

BMW Motorrad Navigator V / VI — 7.4V Li-ion Replacement Battery (361-00063-00)

This is a 7.4V, 920mAh Li-ion cell built to replace the original battery in the BMW Motorrad Navigator V and Navigator VI 6 Endurance GPS units. It fits the mounting footprint at 52.70 × 34.40 × 10.60mm and matches the OEM voltage rail the navigation board expects. Drop this in when the original cell no longer holds enough charge to complete a ride.

• Navigator V and VI shared platform: Both units run the same 7.4V two-cell Li-ion pack with the same connector and BMS handshake. The Navigator VI Endurance variant uses identical cell dimensions and voltage thresholds, so one part number covers both generations.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge passes on the Navigator V board. The BMS accepted the pack without fault flags, and the protection circuit held cutoff cleanly at the low-voltage threshold without tripping early.
• Cold-start satellite acquisition after power removal: After fitting this cell, power the GPS on outdoors before you ride. A full power interruption clears the warm-start cache, so the receiver runs a cold start — expect the first satellite fix to take 5–10 minutes. Subsequent power cycles lock in under a minute once the almanac is rebuilt.

Why the Navigator V shuts off without warning at low battery

The Navigator V reads battery level from a voltage curve that the device calibrates over time. After a battery swap, that curve is out of sync with the new cell. The device may show two or three bars and then cut off seconds later because the shutdown threshold is hit before the indicator catches up. Run two or three full charge-discharge cycles to let the device re-calibrate the voltage-to-percentage mapping. After that, the low-battery warning will fire at the correct point — around 6.8V under load.

Saved routes and POIs missing after battery replacement

Some Navigator V firmware versions hold recent route data and POI caches in battery-backed RAM rather than flash storage. A complete power removal — which happens during a battery swap — clears that volatile memory. Favourites stored to the internal flash partition survive, but unsaved tracks or recently imported POI sets may not. Before swapping the cell, export any active routes via the USB connection to a PC using the BMW Navigator software, then re-import after the new battery is fitted and the unit powers on cleanly.
