I've purchased a Perko four position switch (1, 2, All, and Off), and was about ready to purchase a second battery for my boat, but the battery I was looking at was not an exact match to the one I have. I was afraid I'd fry my alternator or starter with a battery that was not an exact match.
The battery that came with the boat is a Model 24, with 650 Marine cranking amps, 525 Cold cranking amps.
Can I buy a battery with 600 or 700 Marine cranking amps, or do I have to have an exact match to what came with the boat?
Sorry for the simple question. As always, thanks for the advice.
