The ANBTS7500(F) series battery tester from Ainuo company 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 reliable testing tools for quality control in the production, warehousing, and outbound processes of single cells, battery modules, and battery packs.

　　The ANBTS7503(F) series battery tester offers multiple ranges of open circuit voltage (6V/60V/100V/300V) and AC internal resistance (3mΩ/30mΩ/300mΩ/3Ω/30Ω/300Ω/3kΩ) testing. The tester is suitable for AC internal resistance and open circuit voltage testing of consumer batteries, power batteries, battery packs, and battery modules.

　　The ANBTS7510(F) series battery tester provides multiple ranges of open circuit voltage (6V/60V/100V/300V/1000V) and AC internal resistance (3mΩ/30mΩ/300mΩ/3Ω/30Ω/300Ω/3kΩ) testing. The tester is suitable for AC internal resistance and open circuit voltage testing of 800V high-voltage power batteries and energy storage batteries.

　　High precision testing：

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

　　Open circuit voltage range from 10uV to 1100V, with 0.01% accuracy, and multiple ranges.

　　Comparator function:

　　The battery 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.

　　Reliable testing：

　　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. LANRS232 communication interfaces, external I/O interfaces, USB data storage and copying.
