BTMobile ProS

Works Great!!!

I used this and my "ONE" scan tool to test my vehicles batteries. It shows all the info I need to make a decision on their health. I can continue to track these batteries through their lives and replace them when they are weak. Gives state of health in percent, cranking amps, internal resistance and battery voltage. Saves a file in my ONE scan tool to view later. Nice!!

Both work like a dream synced up with my scand tool with no problem

Great Diagnostic Tool

I have used it several times, very accurate & easy to use.
