Altina HXE-W01 GPS Receiver Replacement Battery 3.7V 1000mAh

Altina HXE-W01 Bluetooth GPS Receiver — 3.7V Li-ion Replacement Battery

This 3.7V 1000mAh Li-ion cell replaces the original battery in the Altina HXE-W01 Bluetooth GPS Receiver. It restores power to a portable GPS unit used for outdoor navigation and vehicle guidance. Dimensions are 52.96 x 33.64 x 5.15mm — confirm these against your existing cell before fitting.

• HXE-W01 platform fit: The HXE-W01 runs a single-cell 3.7V Li-ion architecture. This replacement matches that voltage rail and physical footprint, so the BMS handshake completes without fault codes on power-up.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a GPS receiver platform at 3.7V nominal. The BMS held cutoff correctly at both low-voltage and overcharge thresholds with no thermal events.
• Cold-start tip after fitting: After fitting this cell, power the unit on outdoors before your first navigation session. A full power interruption forces a cold satellite start — expect 5–10 minutes to acquire a fix the first time versus under a minute for subsequent warm starts.

GPS accuracy reduced at low battery on the HXE-W01

As cell voltage drops toward the low-voltage cutoff, some GPS receivers reduce RF receiver sensitivity to protect the battery. On the HXE-W01, this shows as a wider position scatter or a fix that jumps between coordinates. The GPS chipset draws more current during active satellite tracking than during standby, which accelerates the voltage drop. Recharging before the unit drops below 3.5V prevents the receiver from entering this reduced-sensitivity state.

HXE-W01 shutting off without any low-battery warning

The battery indicator on the HXE-W01 reads estimated charge, not live cell voltage. After a full power cycle — such as a battery swap — the fuel gauge is uncalibrated and can show bars remaining right up to shutdown. The BMS cuts power at the hardware low-voltage threshold regardless of what the indicator displays. Run one full charge-to-cutoff cycle after fitting this cell to let the gauge recalibrate; voltage should read above 3.6V at the point the indicator first drops to one bar.
