i-Blue PS3200 GPS Navigator Replacement Battery 3.7V 1050mAh

i-Blue PS3200 — 3.7V Li-ion Replacement Battery

This 3.7V, 1050mAh Li-ion cell replaces the original battery in the i-Blue PS3200 handheld GPS navigator. It fits the PS3200 directly and restores the device's ability to power the GPS receiver, display, and route-tracking functions. Voltage and capacity match the original specification.

• PS3200 platform fit: The PS3200 runs a single-cell 3.7V Li-ion architecture. The BMS in this unit monitors cell voltage directly — a mismatched cell voltage or connector pinout will prevent the device from powering on at all, not just reducing capacity. This cell matches both.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the PS3200 platform. The BMS accepted the cell without fault flags, charged to 4.2V at cutoff, and the GPS receiver initialised normally on first boot.
• Cold-start behaviour after swap: After fitting this cell, power the PS3200 fully on outdoors and let it acquire a satellite fix before relying on it for navigation. A full power interruption wipes the GPS receiver's ephemeris cache, triggering a cold start — first fix can take 5–10 minutes outdoors. Subsequent warm starts return to under a minute once the cache rebuilds.

GPS accuracy reduced at low battery on the PS3200

The PS3200's GPS receiver draws consistent power from the cell to maintain signal sensitivity. As cell voltage drops toward 3.4V, some GPS units reduce receiver gain to conserve power — this shows up as position drift or dropped satellite count before the device shuts off. If you notice position accuracy degrading mid-route, the cell is likely near its discharge threshold. Charging or swapping the battery before voltage drops below 3.5V keeps the receiver running at full sensitivity.

PS3200 shutting off without warning during active navigation

This happens when the battery indicator loses calibration after a cell swap — the device's fuel gauge still references the old cell's discharge curve. The PS3200 hits its low-voltage cutoff threshold before the on-screen indicator shows critical. To recalibrate, run the new cell down until the device shuts off naturally, then charge uninterrupted to full. After one full cycle the indicator tracks actual cell voltage correctly.
