Major Features

Reads Battery Information stored inside the battery controller even the battery is faulty and not detected by the laptop.

Performes Quick Heath Test by analyzing the behavior of the battery during the lifetime.

Reads Cells Voltage in Seconds even the battery is damaged, faulty or not detected by the laptop. This great feature can be used in recycling/extracting good cells from faulty laptop batteries.

Checks if the battery is Locked for charging or discharging. When the chip inside the battery detects a malfunction then the battery is locked for charging or discharging (Permanent Failure).

NLBA1 device Charges almost All Laptop Batteries with a maximum current of 3.2 Amps. A great feature that helps you know if a battery can be charged by the laptop. The stop charging conditions are customizable.

The Charging Process is Safe because the battery charging protocol is respected. More, the device monitors continuously the battery parameters and stops charging immediately an error is detected.

On an Intuitive Graphic, the battery current and voltage are plotted to offer a great experience in zooming, tracing and analyzing the values.

During charging process, parameters like state of charge, max. charging current / voltage or charging time are Recorded.


Discharges the batteries with a current down to -3.2 Amps. Customizable stop discharging conditions.

Measures the real battery capacity during the discharging process.

Track the cell’s voltage on the graph. A fantastic feature that lets the user analyze the voltage drop of each cell and estimate how good the cells are.

The device can dissipate a power of 50w. The fan speed is controlled in a smart way to assure maximum power dissipation while keeping the noises as low as possible.


NLBA1 device can Calibrate Almost All Laptop Batteries. A laptop battery that is not calibrated will show incorrect information to the Operating System.

Fully Customizable Calibration Process. A calibration cycle means the battery is fully charged > fully discharged -> fully charged. All these three phases are fully customizable (time, current,  state of charge, temperature, etc.).

The PC Software shows capacity before and after calibration.

During discharging cycle the Real Battery Capacity is measured.


The device can compute Internal Cell Resistance based on the DC load method. The resistance is measured using the battery high performance chip able to achieve a resolution down to 1 mOhm.

The Cell’s Health is estimated based on the internal cel’s resistance and the cel’s temperature and it is displayed as Good, Poor or Bad. With this feature, the cells can be checked within seconds.

Wake Up The Battery is a feature that can revive those laptop batteries that are over-discharged but still not locked (those batteries that are stored for a long period without charging).

The PC Software draws the configuration of the cells inside the battery.



Safety Features

  • Protected Communication Wires. Data lines are protected against any kind of short between data lines or between data lines and power lines.
  • Over Current Protection. The device disconnects the power path in case the charging/discharging current exceeds 3.0 / -3.0 Amps.
  • Over Temperature Protection. If the heatsink temperature sensor reports a temperature higher than a safety threshold the current is decreased.

  • Built-in Microcontroller. A high-performance microcontroller monitors continuously internal battery sensors and reacts in a very short time.
  • Reverse Battery Protection. The device is protected in case the power lines are accidentally reversed and it recovers immediately once the error disappears.
  • Diagnosis interface. Our PC Software offers an interface to diagnose the tool, to read the temperature sensor, turn the FAN, set output voltage or even to read error memory.
  • Intelligent FAN Control. The speed of FAN is adjusted based on the heatsink temperature keeping the noise as low as possible.
