I bought Duralast deep cycle batteries at O’Reilly auto parts . I also added a two bank Noco charger which I mounted on the boat. The charger works great for a trolling motor setup with 2 batteries. I have a Minn Kota iPilot trolling motor 70 lb of thrust.

Trojan is probably the best. I always have a backup battery.

Trojan is probably the best. I always have a backup battery. Doesn't take much room.

Two batterys with a Perko switch. That way you can charge or discharge both at the same time. So running out you charge both. Once on the grounds turn the switch so you use only one battery for you electronics, windlass etc. You will always have a fresh battery for starting. I always used to use both batteries for starting--just my way of doing things.

Is Trojan the name of your battery? I've never heard of that brand.

Hey Saw, check into reliability of the optima batteries before you buy. I heard they sold out and quality is suffering from my battery supplier. You might look into Odyssey brand. Seems to be the premium performance brand now. I bought an Odyssey for my car. It starts like any battery. Engine shuts down when stopped and restarts so it does get a work out. Only time will tell.
Just a heads up.

I worked for Johnson Controls for 25 years the best battery is grp. 27 29 or grp31 for your trolling motors if you have
room for them 12 volt deep cycle is great for your start and fish finders . but always make sure they are fully charge before you get to the boat ramp. Your best buddy is a set of jumper cables for that just in case we all need to get back to the boat ramp........

fish on

The Home Depot marine batteries they carry are Exide, they have group 27 and group 31's, the 31's are 115ah which is a pretty good capacity. The 27's are less than a hundred bucks, the 31's $120 or so.

How batteries last in terms of performance depends on how deeply they are drained before charging. There are differing opinions, but even deep cycle batteries made to go through repeated discharge and charging cycles don't like to be fully drained. Using a bigger battery that isn't typically drained as deeply before charging will make the battery last longer and have more power for longer times than the one that is used until it dies.

Best advice rather than say you can use a battery for an extra day because it has the power for it is to charge it anyway if you can so that the battery is fresher and stronger. A battery used well within capacities just lasts longer. If a battery sat for a few weeks top it off with a fresh charge.
