This is not a matter of saying "charge it up". This is electrochemical analysis of the state of the chemistry INSIDE of the battery to determine if it has gone to a high resistance state and how much of the initial capacity (in Ah and CCA) it has retained/lost.
I dont know how to explain it to you any better than that. You do NOT have to load test a battery to determine if it is good. This sends a specific signal current across the battery to determine HEALTH. Not just charge state.
It is another type of analysis. You have to fully charge a battery for a resistive (carbon pile or other) test, but this is not a resistive test like that. It is a different, newer type of electrochemical impedance measurement. Because it is a DIFFERENT method, it doesnt need to be charged.
Power capability is contingent upon knowing the INTERNAL resistance of the battery. This type of tester does it without having to load the battery with 500A. It is a smarter means of testing the internal characteristics of the battery.
