Esaote NL2044 MyLab One Replacement Battery 14.8V 6600mAh

Esaote MyLab One Series — 14.8V Li-ion Replacement Battery (NL2044)

This 14.8V 6600mAh Li-ion battery replaces the OEM pack in the Esaote MyLab One portable ultrasound system. It fits the MyLab One, MyLab One Vascular, MyLab One VET, and mylabone variants using OEM part numbers NL2044, NL2044HD, and NL2044LV. Capacity matches the original 97.68Wh specification.

• MyLab One platform compatibility: All listed MyLab One variants share the same 14.8V battery rail, connector pinout, and BMS communication protocol. One pack covers the full range — clinical, vascular, and veterinary configurations use the same bay and the same BMS handshake sequence.
• Bench tested on actual hardware: We ran this cell through full charge-discharge cycles and monitored the BMS handshake at startup. The pack completed power-on self-test communication without fault flags and held stable voltage under the ultrasound system's active imaging load profile.
• First boot after installation: After fitting this battery, let the MyLab One complete its full power-on self-test cycle without interruption. The device runs a BMS verification routine at startup — cutting power mid-sequence logs a false battery fault that persists until the next clean reboot. Do not press any keys or interrupt the boot screen.

MyLab One not completing boot sequence on a new battery

The MyLab One runs a BMS learn cycle on the first few startups with a new cell. If the pack has not yet completed this cycle, the device may stall at the boot screen or display a battery communication error before reaching the imaging interface. This is not a hardware fault — the BMS is profiling the new cell's charge characteristics against stored OEM thresholds. Run one full charge-to-discharge cycle before clinical use to allow the BMS to calibrate. After that cycle, boot errors from battery mismatch should clear.

Charge indicator not reaching 100% on the first full charge

On the first charge after installation, the MyLab One's charge IC applies a conservative current limit to an unrecognised cell — this is standard behaviour for medical-grade charge management circuits. The indicator may plateau at 95–98% and stop climbing even after hours on charge. This does not mean the pack is faulty or undersized. Complete one full discharge during normal use, then recharge from below 20% — the charge IC recalibrates its end-of-charge threshold and subsequent charges will reach the full 14.8V termination point.
