Esaote MyLab 25 Gold Replacement Battery 14.4V 7800mAh

Esaote MyLab 25 Gold / MyLab 30 Gold Series — 14.4V Li-ion Replacement Battery

This is a 14.4V 7800mAh (112.32Wh) lithium-ion battery for the Esaote MyLab 25 Gold, MyLab 30 Gold, MyLab Alpha, MyLab Gamma, and two additional MyLab platform variants. It powers the portable ultrasound system during abdominal, cardiac, vascular, and obstetric imaging procedures. Voltage and cell configuration match the original pack's requirements for the onboard BMS handshake.

• MyLab platform compatibility: The MyLab 25 Gold, 30 Gold, Alpha, and Gamma share the same 14.4V battery bay and connector pinout. The BMS protocol across these models communicates on the same data line, so one cell configuration covers the full group without requiring firmware exceptions or adapter cables.
• Bench tested on actual hardware: We ran this pack through full charge-discharge cycles on the MyLab platform and monitored BMS communication throughout. The charge IC accepted the cell and the BMS did not flag an authentication error or trigger a false low-battery alarm after the first complete cycle.
• Post-installation self-test handling: After fitting this battery, allow the MyLab system to complete its full power-on self-test without interruption. The BMS runs a verification sequence at startup — cutting power during this window causes a fault flag that persists until the next clean reboot, and the device will alarm low battery even on a full charge.

Why the MyLab system won't complete its boot sequence on a new battery

The MyLab platform runs a BMS learn cycle during its first few charge-discharge passes on a new cell. Until that cycle completes, the charge IC applies a conservative capacity ceiling and the device may stall partway through boot, treating the battery state as unverified. This is not a fault with the cell — it is the system's protection logic behaving as intended on an uncalibrated pack. Run one full charge followed by a complete discharge under normal imaging load, then recharge to 100% before relying on the battery in a clinical setting.

Charge indicator not reaching 100% on the first charge cycle

On first charge, the MyLab charge controller limits current to a reduced rate until it has mapped the new cell's internal resistance profile. The fuel gauge will plateau at 90–95% and stop climbing, which looks like a faulty cell but is the IC applying a deliberate cap. Do not cycle power repeatedly trying to force the indicator up — that resets the mapping process each time and extends the calibration period. Let the device sit on charge until the controller releases the cap, then discharge fully under load and recharge to complete calibration. After that first full cycle the indicator should reach 100%.
