Battery Life Tester

CategoryBattery Internal Resistance Tester

The AT851 battery life tester is a stand-alone electronic load offering four load operating modes (CC, CV, CP and CR) together with battery life testing that meets the national standard. It includes all functions of the AT8512 - dynamic testing, list testing and comprehensive testing - plus battery life testing. Together with the instrument's internal file editor or the PC software, writing files becomes simpler and easier.

The AT851 supports 485 and RS232C interfaces and enables multi-unit communication. Compatibility with the standard SCPI protocol makes computer programming more convenient.

Besides testing ordinary linear and switching power supplies, the AT851 performs battery life burn-in testing even better, meeting the requirements of battery manufacturers.
