Default Running 2 batteries

I'm about to replace 2 batteries in the boat, just wondering what is the preferred selection. Both will be 24 series. I know one should be a starting battery, but debating on whether the second should be a dual purpose (starting and deep cycle), or just a deep cycle. I've heard different opinions on this, just looking for more I guess. Thanks.

I vote for 2 identical dual purpose marine batts

If accessing them to check/add water is easy, get lead/acid

If it's a PIA (like every boat I've ever seen) get no maint AGM's

in total agreement....but if you are racked or in storage without a charger for weeks ,I would opt for AGM's due to their low discharge rate...

Thanks for the help. So I guess it'll be 2 dual purpose batteries. They are hooked up to a perko switch also. Should I leave it on "All" all of the time when running the boat? Or just set it to one and have the other for backup?

set on #1 on the way out, #2 on the way back - "both" only for starting emergencies...

Check out all of the recent battery & ACR threads (use the Search function)

Adding an ACR (automatic charging relay) eliminates the need to select which battery to charge via the switch.

Here is one with a diagram:
