I need to replace my old battery. I want to buy a new one, but I dont know alot about batteries. What is the best brandin yall's opinion. I need a lead acid deep cycle. It needs to have a RC of around 200. I jsut want a reliable, powerful battery, but I dont know what brand is best. I done want to spend money and have it not be the bettery i need. Thanks!!

I suggest the Everstart Marine battery from Wal Mart. Excellent value.

That does not compute. You are talking about ONE battery,
and DEEP CYCLE. If it's starting your motor, it shouldn't
be deep cycle. And if it's running a trolling motor, it
shouldn't also be starting your motor.
From the name "NausetBoy", I'm going to assume a single motor
If you just start it up, drive around, come back, get a

If you have a trolling motor, you should have two batteries:

Hard to beat Walmart batteries.
I use them in every vehicle/equipment/boat that I own.
Good product and no question-new battery warranty.

While I am not a big fan of West Marine, their Dual Purpose group 24 battery is a good battery for your needs and a very good value.

IMHO, if you're going to rely on a single battery, especially when it could be pounded in chop out in Mobile Bay, it should be an Absorbed Glass Mat (AGM) battery.
The construction is more rugged than the typical flooded cell battery.
It has a lower internal resistance and less voltage drop when starting.
It has a lower self-discharge rate, not requiring charging nearly as frequently between uses.
It doesn't outgas hydrogen and corrosive mist when charging.
It doesn't leak corrosive acid if tipped over.
It DOES cost more and doesn't have as many amp-hours as a conventional flooded cell battery.
AGM batteries are NOT gel cells! The gel in gel cells can harden over time and crack, reducing the capacity.
The most widely recognized AGM battery is the spiral-wrapped Optima brand, however, AGM batteries are also available in the standard battery form factor, which uses more of the volume, and has more capacity than the spiral-wrapped design. Concord Lifeline is the most popular AGM battery with RVers, but there are also other brands which offer AGM batteries.

This is for my 14' Skiff to power trolling motor and fishfinder. Sorry, I shoudl have said something earlier.

Thanks Again to all, I am going with the EverStart Marine Maxx.

I think an AGM battery is overkill for most whaler uses.
I have a flooded battery and I haven't had any of the problems
it's supposed to solve. Maybe for an offshore racer.
If you do get one, be sure to read the directions. After the

I've ridden motorcycles for 40 years now and never needed a helmet, on the street. I've driven a car for nearly that long and never needed a seat belt or air bag. I'll take the extra edge offered by an AGM any day. Just because we've never needed these things doesn't mean they're overkill.

I would talk with the guys at NASA and see what kind of batteries they are using on the Mars lander mission.

I have to take issue with the WalMart Everstart Batteries, at least for older motors. The ones I have seen and consequently purchased are sealed and maintenance free, not allowing one to top off the electrolyte with distilled water. That equals abnormally short life and overcharging from the alternator on some motors. Newer motors (Rather non ancient) have more sophisticated charging systems that do not boil off the electrolytes as easily. However, I still hear cases of low fluid even on newer boats.
If you buy a flooded battery, make sure you can top it off with distilled water. The West Marine and Interstate batteries fit the bill well.

That is a good point about charging system effects. On my rather old and vintage outboard motors, all three of them have completely unregulated charging voltages and often exceed 16-Volts to the battery. This can result in some over-charging and loss of water from the battery.

I buy Wal-Mart's brand because of the warranty. Most are 2-3 years but when my batteries get close to the end of warranty, I check them with a capacity tester and if bad they go back for a new one...no questions asked. It's only occasionally that I find a bad one but I run too many batteries( 2 for each diesel )not to check them.

If you boil all the water out of a Walmart battery and it is still in warranty you can take it back and get a new one......even if the caps are sealed.

I don't have stock in Walmart but I do take care of the landscaping and parking lot in Elizabeth City, NC

Sure Jim that is a good plan for the multiredundant configuration that you have, but I contend that if flooded (wet cell) battries are used on a boat, the user should have a way to maintain the electrolyte, rather than return them for possible recycling.
This is especially important for smaller, single battery Whalers. A shorted battery that cannot be checked for health will equal a tow at some point.
However, this is not a universal problem. Sleep well tonight fellas... Geeky, nitpicking subject.
