The ANBTS7500(F)Series Battery Tester utilizes a 1kHz AC constant current source and four-terminal method to measure the AC internal resistance (ACIR) and open circuit voltage (OCV) of lithium batteries, providing a resolution of the AC impedance as low as 0.1uΩ and excellent anti-interference ability.

The ANBTS7500(F)Series Battery Tester is widely applied in processes such as the formation and grading of the cell, the online screening of the battery in the module and battery pack, and the offline detection, etc.

High Precision Testing

Battery internal resistance ranges from 0.1μΩ to 3.1kΩ, with 0.5% accuracy, and 7 ranges.

Open circuit voltage range from 10μV to 100V300V, with 0.01% accuracy, and multiple ranges.

Comparator Function

The battery's internal resistance and open circuit voltage have comparator function switches, which can be used to set upper and lower limits for resistance and voltage, respectively, compensating for testing.

Test Reliability

AC four-terminal method testing, with 4mm diameter coaxial contact points and interference-resistant testing cables. Contact detection function, with programmable anti-spark design.

Convenient to use

Touch screen operation, windowed menu. LAN RS232 communication interfaces, external I/O interfaces, USB data storage and copying.

Quality control of the production, warehousing, and outbound processes of lithium battery single cells, battery modules, and battery packs.
