Navigon 2510 Replacement Battery 3.7V 750mAh UH0600905

Navigon 2510 / 2510 Explorer — 3.7V Li-Polymer Replacement Battery (UH0600905)

This 3.7V, 750mAh Li-Polymer cell replaces part number UH0600905 in the Navigon 2510 and 2510 Explorer portable GPS navigators. It restores power to the unit when the original cell no longer holds charge. Dimensions are 51.03 × 33.73 × 4.41mm — measure your existing cell before fitting if you are unsure.

• 2510 and 2510 Explorer compatibility: Both models run the same 3.7V single-cell architecture with identical connector pinout and BMS communication protocol, so one cell covers both variants without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the 2510 platform and confirmed the onboard BMS accepted the cell without flagging a fault condition and that charge termination operated correctly at full capacity.
• Cold-start satellite acquisition after swap: After fitting this cell, power the unit on outdoors before driving. The GPS performs a full cold start following any complete power interruption — first satellite fix typically takes 5–10 minutes. Subsequent warm starts drop to under a minute once the almanac data is cached again.

GPS accuracy reduced at low battery on the Navigon 2510

When cell voltage drops below roughly 3.5V, the 2510's power management circuit reduces current available to the GPS receiver module. Lower receiver sensitivity means the unit struggles to maintain a strong signal lock, particularly in urban canyons or under heavy cloud cover. The result is position drift or intermittent rerouting even when the route itself is correct. Keeping the cell above 3.6V during active navigation maintains full receiver sensitivity.

Battery indicator shows charge remaining but unit shuts off without warning

This happens when the onscreen fuel gauge is calibrated to the original cell's discharge curve, which differs from a fresh replacement cell. The indicator reads optimistically until the BMS hits its hard voltage cutoff — typically around 3.0V — and the unit powers off mid-route. Run two or three full charge and discharge cycles to let the 2510 recalibrate its gauge against the new cell's actual curve. After that, the low-battery warning will trigger at the correct threshold before shutdown occurs.
