One of my batteries is Toast. 1 year old. Obviously didn't like the move from Portland to new York to Mississippi. ( was dead when it got to ny I think).
Anyway, looking to replace.
It's a group 24. Nobody around has a normal cranking marine grp 24 wih equal cca as what's in there.

Ay issue with having a slightly less cca battery? Not going with gel cells, but any other options or suggestions?

I really like the interstates I have run the past. The boat came with Deka batts. Nearest Deka dealer is in little rock. Not worth the trouble.

My boat came with two deep cycle interstate group 24 marine batteries from the factory.

From the dealer, boats don't have batteries in them from the factory at least that is what I was told. I think it's a dealer brand preference

Brad I went with any brand that fit the specs, I had some interstate and some exide in the obv, replaced one last year after four years. Most batteries are made by a few companies anymore . I may have gotten mine at SAMs club or Walmart.

SAMs does carry the optima blue tops , kinda spendy but here they are the best.

Thanks
How you are correct. They are dealer install.
WalMart Maxx are close. I've just had good luck with interstates high cca batt.
I am probably going to Hattiesburg today so I'll look there.
Didn't know if mixing starting and deep cycle made a diff.

Seems like deep cycle would be better suited for stereo.

Mine were split as well. I think if you bank them together they need to be the same type.
Not sure what the xlv has in them yet as I have yet to pull the cases. I will soon cuz I would like to relocate one to create more space.

Have you attempted to charge and then test the battery? You wouldn't abandon your car on the side of the road because it ran out of gas, you would refill it and keep going, right! A discharged battery is not necessarily a bad battery. Have it tested with a conductance tester like the Midtronics, rather then the old style "toaster-tester" with the heater grid. These offer a far more accurate test of the battery's condition.

If you do need to replace, stick with a quality brand-name Group-24 marine starting battery, and you should be fine. I would not sweat a slight difference in CCA's.

Thanks
I have kept them on Trickle all winter.
#2 when switched on my Perko will not Power ANYTHING. so, i'm assuming it is DED dead

good suggestion on testing though as i need to make certain it is the battery not the switcher

I have run several weekends with perko on 1and2

and get nothing out of the #2. also notice that when running, the voltage stays around 12, not the traditional upper 13 while charging, so i am assuming that the dead battery is pulling off

I'll pull and take to get tested

Bad question to ask bwebb. He'd leave it and just buy something new. You just can't hide the kind o' coin that boy has.

So, there you go Brad. I'll even help you out here and cut you a check (don't cash it for a few weeks tho) for a couple thousand and you can just get ya some new batteries that come with the new boat.

After getting the battery tested, then recharged or replaced depending on the outcome of the test, I would get a DVOM on them with the engine running just to be sure the alternator is charging correctly and the switch is operating correctly and everything is connected properly. is there a chance that the a ground is left off that connects batt #2 to batt #1? This would prevent it from recharging off the alternator, and possibly your trickle charger depending on how you have things configured.

How about this? Wasn't battery. It was battery ground. Can't find where it was grounded but realized it was not at all connected.
Does the second battery ground to first?

Grounded off #1. All is great in battery world now.

So, does this mean I'm not getting a Supra on the cheap?

Glad it was that simple.

Drew, would you give up the mojo or a supra? Hmmm....

No, probably not. I think the Mojo is probably the best surfing boat in the SC lineup. But, I do like some of the bling on the Supra, especially the Vision system and the progressive tower with the Z5.
