Battery and CCA

[jh121]

Hi all, wonder what is the minimum size battery I can get away with solely for starting my old Mariner 150 hp outboard. In terms of CCA ( or Ah ... ) ? Thanks.

Manual for a late model Mariner 150 two stroke says 630 Marine Cranking Amps (MCA) or 490 Cold Cranking Amps (CCA).

Therefore this could do the job - if it fits your boat

Or this one would save £10 and 10lbs if purely for engine starting

But it would be wise to start with any dimensional constraints and visit a site which allows you to choose a battery based on the dimensions etc as well as CCA/ Ah

Or for a compact AGM battery that can be laid on its side if needs be consider a Red Flash1100 ... http://www.dmstech.co.uk/red-flash/red-flash-high-rate/

Thank you all for feedback. I now have a fair idea of what to get.

This company is a good supplier of batteries which give dimensions and the layout of the positive and negative posts
