LG LN700 GPS Navigator Replacement Battery 3.7V 1100mAh

LG LN700 / LN710 Series — 3.7V Li-ion Replacement Battery (EAC30173401)

This is a 3.7V, 1100mAh Li-ion cell built to the EAC30173401 spec for LG portable GPS navigators. It fits the LN700, LN704, LN705, and LN710 series, along with four additional LG navigator models that share the same connector and voltage rail. Swap it in when your unit no longer holds a charge or powers off unexpectedly during navigation.

• LN700 / LN704 / LN705 / LN710 series fit: These models share the EAC30173401 footprint, connector pinout, and 3.7V single-cell architecture. The BMS on each accepts this cell without a handshake conflict.
• Bench tested on actual hardware: We ran charge and discharge cycles on this cell and confirmed the protection circuit trips correctly at over-voltage and under-voltage thresholds. Cell temperature stayed within spec throughout.
• First-fix cold start after fitting: After installing this battery, power the unit on outdoors with a clear sky view. The GPS performs a full cold start after any complete power loss — first satellite acquisition takes 5–10 minutes. Subsequent warm starts drop back under a minute once the almanac data is re-cached.

GPS accuracy reduced at low battery on the LN700

When the cell drops toward the low-voltage cutoff, some LG navigator firmware reduces receiver sensitivity to extend operating time. The unit stays on, but satellite count drops and position error increases — often showing the device half a block off. This is a firmware-level power-saving behaviour, not a GPS hardware fault. Keeping the cell above 3.5V during active navigation avoids this sensitivity reduction entirely.

LN700 shuts off without warning before the battery indicator hits empty

An aged or deeply discharged cell loses its ability to accurately report state-of-charge to the fuel gauge circuit. The display may show two or three bars remaining when the cell voltage actually hits the BMS cutoff threshold and the unit drops dead. This is a calibration drift issue — the gauge was last calibrated on a cell that no longer behaves the same way. After fitting the new battery, run two full charge-to-discharge cycles to let the gauge re-calibrate; the indicator will then track actual voltage more accurately.
