High Precision Battery Tester M340A

$12,312,312.00

The LANHE M340A is a high-precision battery testing instrument engineered for advanced battery and capacitor material research, half-cell, three-electrode, button cell, and small-capacity cell testing.
Designed for research-grade accuracy, it features a -5V~5V full-range controllable voltage and ultra-fine current resolution down to 1μA, with industry-leading accuracy of ≤±0.01%FS for voltage and current. It supports high-rate fast charge research, delivering ≤±0.01%FS capacity tolerance at 30C and ≤±0.1%FS at 100C, and self-defined pulse testing with a minimum pulse width of 2ms.
The system fully records all critical parameters: voltage, current, capacity, energy, efficiency, internal resistance, and more. It is equipped with an analog UPS and data storage to prevent data loss from crashes, power failures, or network issues. It also supports a full suite of performance tests including CLTC/NEDC/WLTC cycle testing to simulate real-world operating scenarios.
With 8 independent channels, 4096 programmable steps, and a 100Hz sampling rate, the M340A is the ideal solution for universities, research institutes, and material laboratories for cutting-edge battery research and development.
