I see on another forum saying the 250 ProXS needs 31 series 1000CCA battery. My 2011 Z9 I just bought has only a 24 series 550 CCA battery and is doing fine. It is 3 years old tho so I’m going to replace it. I found a 24 series battery with 1000 CCA that will fit the battery tray already in position. Does the size matter as long as CCA ‘s are enough?
