Use a STARTING battery only.
​You can hurt the charging system if you use a deep cycle battery.
​Any battery with a cca of 450 or bigger will work.
I have 2 450CCA's

​Trolling motors need a deep cycle.

​IF?? you run a HUGE radio with amplifiers etc. Then the bigger the better.

I've never killed a battery by using the radio or depth finder when going out.

A 2 battery system is great if you worry about a dead battery.
​A switch can allow you to charge both as you run and then switch to a single when setting.
That way you always have a hot battery.

​If the weight is what you worry about? then you can use a lawn mower battery along with the regular one.
​Use the small one when setting and the large for running/starting.

I test my batteries a lot.
​Load tester: 25$ Harbor Freight.
​Hygrometer cheap insurance.

You can have a battery with 12v and it's still bad.
​A dead/weak cell(hygrometer)

A battery charger can be bad even though it shows it's putting out voltage.
Test it too.

Well ive been using the "dual purpose" battery. Not sure if thats the same as a deep cycle but it seems to be doing ok over the last 10x i went out???

​Here's a link to a thread from 2012 about dual purpose batteries.
​The only thing I'd worry about??? charging a dual purpose battery with a charging system made for a regular battery??
I don't know how that would affect the system or the battery??
It's a good read.
There are a few links open them all.
