GE Logiq E10 14.4V Replacement Battery 480304-2 7800mAh

GE Logiq E10 / Logiq S8 — 14.4V Li-ion Replacement Battery (480304-2)

This 14.4V 7800mAh lithium-ion battery replaces the OEM pack in the GE Logiq E10 and Logiq S8 Polaris ultrasound systems. It also fits the Polaris Maru and Ultraschall Logiq P7, sharing the same voltage rail and connector pinout across the platform. Capacity figure is taken directly from the product specification — 112.32Wh total energy.

• Cross-platform fit — Logiq E10, S8 Polaris, Maru, P7: These models share a common 14.4V bus, matching BMS communication protocol, and identical connector housing. A single cell configuration covers the full group without hardware modification.
• Bench tested on actual hardware: We ran charge and discharge cycles through the BMS handshake sequence on Logiq-platform hardware. The protection circuit tripped correctly at low-cell threshold, and the charge IC accepted a full charge without fault codes after the first complete cycle.
• Post-installation self-test cycle: After fitting this battery, let the Logiq system complete its full power-on self-test without interruption. The BMS runs a verification sequence at startup — cutting power mid-boot logs a false battery fault that sticks until the next clean reboot from full charge.

Why the Logiq E10 flags a battery fault on a new cell

The Logiq E10's BMS compares cell voltage and internal resistance against a stored OEM baseline at every startup. A fresh replacement cell has a slightly different impedance profile than a conditioned OEM pack. The system logs this as a battery fault even when the cell is fully charged and electrically sound. One complete charge-discharge cycle recalibrates the BMS learn register and clears the fault on next boot.

Charge indicator stuck below 100% after first charge

On first charge, the Logiq charge IC applies a conservative current limit to an unrecognised cell — it does not push to full termination voltage until the BMS confirms cell history. This shows as the indicator stalling at 90–95% and the system reporting less than full capacity. Run one full discharge until the device shuts down under load, then charge uninterrupted to completion. After that cycle, the charge IC terminates at the correct 16.8V ceiling and the indicator reads 100%.
