It’s relatively common for boats to have two batteries. You might also notice that you have a switch that can go from “battery 1” to “battery 2”. The main reason for the second battery is for an emergency where you find that your primary battery has died and you need to start the engine to get back to land. Another reason why boats would have two batteries is so that the electronics on board run separately from the engine or motor battery. here
It could be as simple as a dead cell in the battery, and won’t hold much of a charge. In this case, you would need to replace the battery. You can take the battery into an auto shop to have it load tested.
I didn’t even think this could be a problem but apparently, it is. I’ve never had this happen to me, but after doing some research on the topic, I found the following information. [links]
I DEFINITELY agree with IOP. Down here, on the west coast of Florida, you've got to run along way to deep water. You don't want to get stuck out there with a sh!tty batt. Electrical systems in the salt water world are a MUST! [links]
20 minutes sounds a little on the short side to produce significan't drain on a battery with a small stereo and 2 speakers. Unless the battery is beginning to fail.
It doesn't sound like that's you, however.
Obviously this would be easy to test by playing the radio when the boat is trailered in my driveway and then checking the battery voltage afterwards, but if my dad is indeed correct that the radio has a significant drain on the battery, then I don't want to shorten the life of my starting battery by discharging it beyond what is safe.
Re: Is the boat stereo a significant drain on battery? here
Invest in 2 batt system. Its just makes all the sense in the world no matter how far out you go or what kind ride you have. its the only way not to have that "feeling" when you go to crank over.
I have one expensive deep cycle battery that is for running things when anchored. And I have a diehard that is the one for the chevy 350. 880 CCAs on a switch.
The best marine battery for you depends on what type of boating you plan to do. Do you head out for the day to pull your kids on water skis? Are you trolling for trophy fish from sunrise until sunset? Or, perhaps your boat is your home. All of these applications put different demands on your boat battery. Let’s look at how this impacts your choice of the best boat battery for you and what options are available.
Your application will determine if you need a starting battery, a deep-cycle battery system, or maybe you only need a single multi-purpose battery. The best boat battery for you will always depend on how you’re using it. Regardless of your application, there are some things to keep in mind when looking for any marine battery.

To bring the batteries up. Then there is the use of solar panels. Solar panels are a way that you will find many sailboaters maintaining their batteries. [links]
Charging a boat battery in the water can be done. But by really only three main ways. That is to use your engine to charge the battery. [links]
If this is the case and the engine’s stator or alternator is not charging. But allowing the engine to drain the battery, here’s how to test it. more
We should see both wires have battery voltage present on them. As long as there is battery voltage there, we can start and run the engine. here
