BENTON Battery Tester app for iPhone and iPad

This battery tester is based on an advance energy recycling technique to test the battery. The
tester provides battery status like internal resistance, temperature and maximum current
delivery by determining battery charging and discharging characteristics. The status provides
criterions for batteries maintenance or replacement.
The battery tester provides two testing modes for users which are fast mode and professional
mode. For fast mode, the tester provides a quick, rough estimation of battery status like
internal resistance, SOH, SOC only. For professional mode, the tester provides more details of
battery status including loading waveform, loading information and battery intrinsic parameters.
Moreover, the tester supports In-Vehicle test including cranking system test and charging
system test. For cranking system test, cranking time and cranking voltage are considered. For
charging system test, charging voltage and ripple voltage are used for determining the health of
the system
