Having to replace 2 of my batteries. I was curious what batteries yall use and which ones give the biggest bang for the buck. Thanks for your input.

Best bang for your buck. They put them on sale often at $20 off.

Everstart Group 31 series at Wal Mart $89, just change them out every 2 years and you will never ever have another battery problem.

Duracell 31 AGM from Sam's club

duracell is the best bang for the buck that i have used. I have only used the lead acid ones just keep water in them.
the AGM they will be my next purchase just so i dont have to add water anymore.
they may be better batteries but not at the same price point.

Is the duracell AGM a good cranking battery for a Yamaha Sho 250 4 stroke? I've read some and some say it's too much battery for a 4 stroke.

say WHAT? .....like free lunches.....thar' ain't no such thing as "too much battery"! ....What you get is lots of "save your butt" juice stored in that battery if you've been running accessories too long for a typical battery to start the outboard.. If you're lucky, the big AGM will still get it done.

When you say "replacing two" is that two for a 24V TM, or 2 of the 3 for a 36V TM? I ask because it is best to replace all in a series connection at the same time. This is because any remaining battery (batteries) will eventually begin to fail, dishing out more abuse of the newer battery(or batteries). Overall, you'll be happier with a set at the same age, whether it's a set of 2 or 3. Just to be clear, a standalone starting battery isn't part of a "set" as it isn't connected to the TM batteries.

Been getting 4 years out of the Everstarts. I replace because I get nervous, not because they quit performing.

What do they mean by too much I wonder? It supplies 12 volts at 800 amps cold cranking with lots of capacity for powering sonars, pumps, lights and such. The one in my boat is 2 years old and still doing great.

Assuming you're replacing 2 trolling batteries, not cranking. I use the group 29 everstart marine maxx for a 36 volt trolling motor. I usually get 2.5-3 years out of them. $100 each and there's a wal-mart at every exit on the highway.

This is what you want.

Replacement every two years......forget that. Too much taking them in and out every two years. Not for me.

I'm looking to replace all three of my batteries, currently in running two 27 Napa batteries on my TM and on 24 as my cranking battery. I'm looking for input..

deka or duracell, same battery, same co. makes both.

I went with deka, 3/27s and a 24.
