The VS I used, IIRC, when put across the battery, the CCA increased and resistance decreased.
If you're using a digital battery analyser and you think you get more CCA, you're being "fooled".
The capacitance altered the phase angle and it looks like you have more CCA.
The same thing as measuring the battery in-car (with capacitiive loads) and out-of-the-car (open circuit).
The problem is the the digital battery analyser cannot measure correctly, when hooked up with capacitive circuits.
But then, it's a good way to sell VS, well, if you believe what you see.
I take a 60AH battery and it measures 600A CCA.
I put a few capacitors across the battery terminals and now it measures 700A CCA.
Even a real 70AH battery may not give you 700A CCA.
So that means the few capacitors is equivalent to a much bigger and more expensive battery ?
Think about free lunch, if it's available, everybody would want one.
I have many cases, when I'm asked to change the battery.
When measured in the car (with everything connected), it measures 400A.
That should be more than enough to start the car, but of cuz it doesn't.
When that same battery is taken out of the car and measured open circuit, it only measures 100A.
That's why it wouldn't start the car.
In-circuit capacitance has caused the analyser to read wrongly. And that's a fact.
