Other than CCA and AH, any other spec we shall take note as well? Like how much max current a battery can release in a sudden or short period of time.
What i noticed recently is my Yokohama Beta NS40 crank quicker than my FB HiDash NS40 and Amaron Hi Life NS60 in the same car.
Besides, the light dim the least when aircond compressor kick in and also engine accelerate smoother with Yokohama Beta.
Which make me feel that Yokohama Beta is Energizer AA battery and the other two are normal AA battery.

FB(New) Dec18-Oct19, Yoko(Used-1year) Oct19, Amaron(New) Oct19-until up to date.
