Default Battery advice.

I have a 16' aluminum starcraft, and 25hp Johnson outboard with electric start. The current battery has sat for a couple years. It will take a charge, but not hold it.
So I'm asking what replacement battery to get. Ill want to start the motor and run a small trolling motor, marking lights at night, and a very small stereo.

What size is your current battery and what kind of budget do you have in mind?

It's a 12v deep cycle rv/marine. About 2x the size of a car battery. My dad used it to run a large trolling motor.
And prefer under $200, but a bit over wouldn't be too bad.

It sounds like a Group 27 or Group 31 battery. IS there any easy way to look at the Model of the battery to be sure?

I ask because, ideally, you would want one you can just drop in to replace what you have without any work to make the new battery fit right.

It's diehard group 29hm, 675cca, 200rc.
And it's currently a bare hull, so I'd prefer to buy the battery, then the bracket as the bracket is 1/10th the cost.

if you are using a trolling motor you going to want 2 batteries. then if you kill one trolling you can still get home.

i have never seen a group 29 battery.

I'm not actually going to be trolling, just using it to occasionally sneak into bayous and inlets to spot wildlife.

I have an AGM type battery that I purchased 8 years ago. Amazing battery, can sit all winter and barely lose a charge. No acid to leak. Will cost a little more than a flooded type battery but worth it in the long run. Battery built by East Penn but purchased through a local parts store.

Honestly, I don't see anything wrong with the battery you have now. It has very good specs for the price point it's at and if it has served you well in the past, I would just swap it out for a new one.

Any battery that has sat unused for several years is going to sulfate and become unusable.

I would suggest swapping it out with the same battery and getting a battery charger for when the boat is being stored. This will help the battery remain in good shape through long periods of storage.

I have recommended these many times as I have several and love them. Great batteries at a great price.

The Duracell AGM batteries at Sam's Club are re-branded DEKA Intimidators, one of the best batteries you can buy. I have had various colored tops of another popular brand batteries and these are better. I think the last pair I bought were grp 31s and they were about 175 each. Last for years. No maintenance. Virtually no loss of charge after sitting idle for six months.

I have a Sam's card. I'll check them out.

Hi all! I'm working with an engineering team to develop a new boat battery charger technology and am looking to collect some feedback from boat owners to help guide my team's design! If you have a few minutes (5-15) to answer this survey, I'd really appreciate it, and you have the option to be entered in a raffle for a $50 Bass Pro Shops gift cards!
