Batteries for adult toy.

I've set up my boat for 2 batteries, one for starting and one for running the anchor light and radio when not underway. Since you are battery geniuses I thought I ask for opinions.

It's time for new batteries so I'm wondering what would be better overall. Two starting/cranking batteries, using the second for the light/radio or 1 starting/cranking and 1 deep cycle rv/marine?

The idea for the backup battery was to be sure I could start the boat after extended light/radio use. So that makes me lean toward the backup actually being another cranking/starting battery.

Thoughts?
Thanks

  • A pair of Duracell AGM deep cycle, also sold as the DEKA Intimidator at boat supply stores.

    If you have the room for two batteries go for it.

    They're pretty cheap at Sam's Club
