Nokia 500 GPS Navigator Compatible Battery 3.7V 1300mAh

Nokia 500 / PD-14 GPS Navigator — 3.7V Li-Polymer Replacement Battery (20-01673-01B)

This 3.7V, 1300mAh Li-Polymer cell replaces the original battery in the Nokia 500 and PD-14 portable GPS navigators. It matches the OEM voltage rail and physical footprint at 63.91 × 41.62 × 4.62mm. Capacity figure is taken from the product data at 4.81Wh.

• Nokia 500 and PD-14 compatibility: Both units share the same battery bay dimensions, 3.7V nominal rail, and Li-Polymer BMS handshake. The same cell works across both without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the Nokia 500 platform. The BMS held cutoff voltage correctly and the protection circuit responded to over-discharge conditions without fault.
• First satellite fix after fitting: Power the unit on outdoors immediately after installing this cell. The GPS performs a cold start after any full power interruption — first satellite acquisition takes 5–10 minutes. Subsequent warm starts drop to under a minute once almanac data is cached.

GPS accuracy dropping at low battery on the Nokia 500

The Nokia 500's GPS receiver draws continuous power to maintain satellite lock. When cell voltage drops toward the lower threshold, the unit can reduce receiver sensitivity to preserve remaining charge. This shows up as degraded position accuracy or intermittent lock loss before the battery indicator reads empty. Keeping the cell above 3.5V during active navigation prevents the receiver from stepping down.

Nokia 500 shutting off without low-battery warning

After a battery swap, the Nokia 500's fuel gauge needs a full charge and discharge cycle to recalibrate its voltage-to-capacity mapping. Until that cycle completes, the unit can hit the hardware cutoff voltage and shut down while still showing bars on the indicator. Run the device from a full charge until automatic shutdown, then recharge fully — one cycle corrects the displayed threshold. Target a full charge to 4.2V before the first navigation session.
