Re: What battery for nissan tldi?
Any major brand of flooded Marine Starting battery should have a 1000 cca battery in a group-27, and many will have them in group-24 sizes. El-cheapo brands at big box stores may not have these specs.
Automotive batteries would work, short term, but are not designed for the marine environment, don't have the expected terminals for the ring connectors on the outboards (so need adapter terminals) and usually suffer premature death due to slamming and vibration.
Yes, you can parallel two identical batteries, if needed, to get total cca where you need it. Be sure they are the same size, type, age, and manufacturer, or they will be constantly in a different state of charge, and one of them will suffer an early fatality. If you do that, be sure that you use appropriate wire and connectors between the paralleled batteries.
