2006 VLX Malibu with Monsoon Engine 340 hp.
I am due for a new starter battery mine is 6 years old. I called my local Malibu dealer and the he told be that I needed a deep cycle battery at least a 550 to 600 cca group 24M battery is all he said.
Well I ended up with a RV/Marine Battery Interstate SRM-27 600 CCA 750 MCA. Not sure what those numbers all mean, but will it work for a starter battery.
It is a group 27 NOT a 24 which i hope is just the size of the battery. The 600 CCA is still the same as recommended.
I picked up the battery for cheap from my families RV dealership and it was the closest to any of the numbers. They did have a size 24M, but it was only 500 CCA. So I went with this one.
This is what it looks like.
