Boat Battery

How can I recharge a 2nd 24V battery in my boat while running the motor with my main battery?
I have a Deep Cycle 24V marine battery for craking, running the boat, etc. I just bout a 2nd battery for my trolling motor. I want to be able to put a charge on that 2nd battery while I am running the motor (cruising, finding new spots, etc). How can this be done?
Thanks in advance!
So basically just run a cable from positive on batt1 to positive on batt2 and same with negative as well?
Hook them up in a parallel circuit.

Do you need a battery on your boat for a trolling motor?
If so any other way to have an electric motor on a 9 to 10ft boat?
Yes all trolling motors need a battery to operate. Sorry never heard of another option unless you leave the trolling motor and use a oar to paddle.

you don't change the electrolyte, ever.
you can add distilled water and when the battery gets a charge it will convert it into electrolyte.
Not all batteries will allow you to do this, as they are sealed.
if a battery sits for long periods of time not being used, they will begin to grow sulfation on the battery cells. it's like plaque on your teeth.
Except with sulfation, you can't clean the cells. you can TRY to charge it with a high amp charger for 10 minutes, sometimes, it breaks the sulfation, most of the time, you just get to buy a new battery.
to keep a battery alive you need a battery maintainer for when the battery isn't being used.
