I pulled my battery today and unfortunatley it looks like i need to replace it. My question is when i was shopping online for the replacement i didn't come across one that had the exact ratings as required in my manual. MY mercury manual states that it should be rated for 465 marine cranking amps (M.C.A.) and or 350 cold cranking amps(C.C.A.) I use a sinlgle battery and not much by the way of electronics. How far off of these recomedations can i actually use without causing any problems?
