Navigon GC500 GPS Navigator Replacement Battery 3.7V 1200mAh

Navigon 8410 — 3.7V Li-Polymer Replacement Battery (GC500)

This 3.7V 1200mAh Li-Polymer cell replaces the original battery in the Navigon 8410 portable GPS navigator. It matches the OEM part numbers GC500, 30.13SOT.001, and 60.13SOT.001. Dimensions are 61.60 × 36.40 × 5.50mm — a direct physical fit for the 8410 battery bay.

• Navigon 8410 fitment: The 8410 uses a flat Li-Polymer pouch cell at 3.7V with a specific connector pinout that carries both power and thermistor signals. This cell matches that voltage rail and connector layout, so the device's charge controller communicates with the battery normally.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the 8410 platform and confirmed the BMS accepted the thermistor handshake without triggering a fault. Charge termination and cutoff voltage both behaved as expected across multiple cycles.
• Cold-start satellite fix after power interruption: After fitting this cell, power the 8410 fully on outdoors and let it acquire a satellite fix before driving. A complete power removal resets the GPS receiver to a cold start — first fix can take 5–10 minutes. Subsequent warm starts will lock in under a minute.

GPS accuracy reduced at low battery on the Navigon 8410

When the 8410 battery drops below roughly 3.5V, the device reduces power to the GPS receiver module to protect remaining charge. This shows up as position drift or slower route recalculation — not a fault with the GPS antenna. Replacing a degraded original cell restores the receiver to full operating voltage. After fitting this battery, allow a full charge cycle before extended navigation use so the device can recalibrate its voltage reporting.

Navigon 8410 shutting off without a low-battery warning

An aged battery loses capacity unevenly — voltage holds steady until it collapses suddenly, so the 8410's on-screen indicator shows two bars and then the device cuts out. The shutdown threshold is voltage-based, not capacity-based, and a degraded cell hits that floor fast. This replacement cell holds a stable voltage curve across its discharge range, giving the indicator time to catch up. After first charge, confirm the battery icon reads full at 4.2V before heading out.
