Starter Battery Size For Perkins 4236

[BlowingOldBoots]

Hello,

Hope you can help. I am away from the boat and need to order up a pair of engine starter batteries for my Perkins 4236.

The electrical system is 24 V and currently I have two 12 V batteries wired in series for 24V of course.

What should the CCA be for this engine?

Thanks,

Alastair
