You likely have a battery selector switch. You only need 1 battery. The other is a backup. If you run your trolling motor, livewell, stereo, etc you might kill the battery. In that case you would just switch to the other battery.

I say these things for the following reasons:

OK, we are going to try to get one of these. How to I know which one is the correct one?

I suppose the cables go on the same way?

Nice, glad to hear she is back up and running! I've had a slow battery drain in my tow vehicle for years. It will kill a battery while sitting over the course of about 3 weeks. After days of fruitless searches trying to find the drain, I eventually just broke down and left it hooked up to a battery tender so that it was always at full charge when I needed it. For my case, a Battery Tender jr. with a cigarette lighter adapter has worked great for me for over 10 years now. If your boat is not protected from the elements, you could also consider the water proof version of the battery tender.
One last thought that has saved me from worrying about any of this on my boat is to install a battery switch, so that you can simply turn off all connections to the battery when you are not using the boat. I currently use this one with two group 27 batteries. You could do something similar if you suspect you have a power drain. You do not need to add the second battery if you don't want, instead you can just get a simple on off switch like this. Though it is nice peace of mind when you are offshore to know you have a backup. Happy boating! Let me know if you have any more questions.
