NLBA1 Laptop Battery Analyzer & Repair Tool – Smart Battery Capacity Tester

Overview 

The NLBA1 (N21 Laptop Battery Analyzer) is a professional-grade diagnostic and repair tool engineered to analyze, test, charge, discharge, and reset smart laptop battery packs. By communicating directly with the battery’s internal Gas Gauge IC via I²C and SMBus protocols, it gives technicians total visibility into cell health, cycle counts, manufacturer data, and locked controller states without opening the battery casing.

Key Features 

• Comprehensive SMBus Diagnostics: Reads real-time internal battery parameters including Design Capacity, Full Charge Capacity, Voltage, Current, Temperature, Cycle Count, and Manufacturer Date.

• Automated Capacity Testing: Runs continuous charge/discharge cycles to plot accurate capacity curves and measure real-world performance under load.

• Gas Gauge IC Reset Support: Clears battery locks, permanent failure flags (PF), and resets cycle counts on supported smart battery microcontrollers (e.g., Texas Instruments BQ20zXX, BQ30zXX, BQ40zXX series).

• Universal Pinout Connector: Equipped with flexible output cables and headers to interface easily with various laptop battery pin configurations (Dell, HP, Lenovo, Asus, Acer, Apple, etc.).

• PC Software Interface: Connects via USB to dedicated Windows software for detailed graphical analysis, report export, and database logging.
