Know whats happening inside your battery
Handy and easy to use,this little device will tell you whats going on inside your battery,more so if your car is equipped with "Idle Stop Go" (ISG) for this to work your battery really needs the CCA (Cold Crank Amp) to be at its peak,how i came across this is my cars ISG stopped working the car started without problems,the battery was reading all the right Volts whether engine stopped or running but after doing some research the AMPS need to read,
Eg....my cars CCA is 760CCA but with this device i found the actual battery CCA which read 560CCA which is way under to operate the ISG
Any car with ISG is a AGM battery basically a dry cell,unlike acid batteries,but the tester works on both types with a easy to use menu.
