Baller rodltg2 Posted March 16, 2015 Baller Share Posted March 16, 2015 Having trouble finding a battery that fits in the box on my 99. No luck at the auto parts stores or wal mart. Maybe the dealer may have one, but I know it will cost an arm.Anyone know who makes one that fits. Only option I've seen is an auto battery, its actually what was in it. Should I just get an auto one, or try for the marine battery? Link to comment Share on other sites More sharing options...
Baller JC McCavit Posted March 16, 2015 Baller Share Posted March 16, 2015 I need to replace the battery in my 1997 Nautique. I want the strongest battery that will fit. What is the best battery for the application? Link to comment Share on other sites More sharing options...
Baller oldjeep Posted March 16, 2015 Baller Share Posted March 16, 2015 You need a marine battery - for vibration resistance. If you look on the existing battery there should be a group size listed on it somewhere. If you provide that then it would be pretty easy to find you one. Typical marine battery/box is a Group 24. Possible that if you have an oddball size in there that you just need to replace your battery box with a more standard size. Link to comment Share on other sites More sharing options...
Baller oldjeep Posted March 16, 2015 Baller Share Posted March 16, 2015 Also - if you can't find the group size on it then provide the measurements or look at this chart (Auto size chart - but marine batteries use the same group numbers, there is a subset of the groups available for marine use) http://www.interstatebatteries.com/content/product_info/auto_interstate_f.asp Link to comment Share on other sites More sharing options...

Baller oldjeep Posted March 16, 2015 Baller Share Posted March 16, 2015 Weird - but OK. Take a look at what group the current battery is and go from there. Link to comment Share on other sites More sharing options...
Baller jpattigr Posted March 16, 2015 Baller Share Posted March 16, 2015 My 97 has a car battery and it has been going strong for at least 6 years. Blocked in with foam rubber and it does not move. Link to comment Share on other sites More sharing options...
Baller oldjeep Posted March 16, 2015 Baller Share Posted March 16, 2015 It is the movement inside the battery that can be an issue. For a slalom tug on a private lake it might not matter, but for a normal boat that bounces off waves and wakes the stronger construction of the plates and case on the marine battery is a must.

Baller thager Posted March 17, 2015 Baller Share Posted March 17, 2015 I have always used an auto battery. Most have lasted 5 plus years. Unless you have major electrical draw when the engine is off there is no reason to use a marine battery for the extra bucks. Link to comment Share on other sites More sharing options...
Baller oldjeep Posted March 17, 2015 Baller Share Posted March 17, 2015 Marine starting battery isn't going to help with a draw anyways. You are describing a deep cycle, which shouldn't be used as a starting battery for a big engine. Link to comment Share on other sites More sharing options...
Baller_ Wish Posted March 17, 2015 Baller_ Share Posted March 17, 2015 I've done the same as @thager. Walmart 750cca bats. easily 4-5yrs in FL. Interesting on the plate construction difference @oldjeep. Did not know that. Small private lake here so hardly any bouncing around but that will make me think twice with my next bat purchase. There is only 10-12$ difference to jump to a marine bat at Walmart. Link to comment Share on other sites More sharing options...
Baller oldjeep Posted March 17, 2015 Baller Share Posted March 17, 2015 Curious how much you guys are paying? An interstate marine battery is about $100 . I've got 2 of them, and when the time comes, I'll spend the $200 to replace them. Pretty insignificant cost in the scheme of things. Link to comment Share on other sites More sharing options...
Baller oldjeep Posted March 17, 2015 Baller Share Posted March 17, 2015 @wish I used to use marine batteries in my jeeps until the spiral cell stuff started to get more reasonable in price. The marine stuff could take the pounding. Link to comment Share on other sites More sharing options...
Baller bassfooter Posted March 17, 2015 Baller Share Posted March 17, 2015 @oldjeep - the '97 - '99 Nautiques (and maybe '00 - '01) have a battery well in the floor under the observer's seat with a snug, carpeted cover. @rodltg2 has the same problem we have on our '98-- the cover won't go all the way down because the battery is too tall. Drives me nuts (not a long trip). Thanks for the advice -- I'll try to remember it when this battery dies. Link to comment Share on other sites More sharing options...
Baller jhughes Posted March 17, 2015 Baller Share Posted March 17, 2015 WalMart EverStart MaXX 65N will do the job. Plenty of guys running this battery with no problems. Link to comment Share on other sites More sharing options...
Baller MarkTimm Posted March 17, 2015 Baller Share Posted March 17, 2015 I just replaced the battery in my 96 SN with an Exide Group 65 from Home Depot. Link to comment Share on other sites More sharing options...
Baller GAJ0004 Posted March 17, 2015 Baller Share Posted March 17, 2015 I have always had good luck with Interstate Batteries. My first one lasted 12 seasons. I just put my third one in last year. My boat is a 1994 Nautique. There should be a decal on the underside of the battery box lid that gives the battery specs. Measure your battery box first..

Baller JAG Posted March 20, 2015 Baller Share Posted March 20, 2015 I have had nothing but 2 years max life out of Interstate Marine batteries on my MB Sports. Switched to standard auto battery (Costco) and going on five years now. Marine batteries are mostly designed for deep cycle, trolling motors and not the best application for your inboard. (Revealed by several sources, most recently, the head mechanic at the local Mastercraft dealer). RPG Link to comment Share on other sites More sharing options...
Baller oldjeep Posted March 20, 2015 Baller Share Posted March 20, 2015 @rpg 3 kinds of marine batteries 1) Marine starting battery 2) Marine deep cycle battery 3) Marine hybrid battery (deep cycle technology but set up to deal with the high current of starting) For your ski boat you would use either #1 or #3 If you are using #2 they are not going to last long when used in a high current starting application. In the case of interstate #3 would be their AGM and ECL batteries http://www.interstatebatteries.com/m/category/marine If your MC mechanic doesn't know the difference - then that would be interesting.

Baller jhughes Posted March 20, 2015 Baller Share Posted March 20, 2015 @oldjeep Would not be surprised if #1 is largely marketing and stickers for the auto equivalent these days, maybe with an extra set of posts. Link to comment Share on other sites More sharing options...
Baller oldjeep Posted March 20, 2015 Baller Share Posted March 20, 2015 @jhughes doubt it. If you look at the most standard sized Interstate marine starting battery (24M-XHD) compared to the same group number and CCA rating auto battery (MTP-24F), the marine battery is 4lbs heavier (48lbs vs 44lbs) - which should be a thicker case, thicker plates, better plate retention and the dual marine terminals. The marine battery is a little taller due to the case - they don't even make an auto battery with the exact dimensions of the marine batteries.

east tx skier Posted March 30, 2015 Share Posted March 30, 2015 Rod, group 65 or group 34 should fit. I'm on about year 5 or 6 with my Delco automotive battery. I spend a fair amount of time on open water. It has lasted a lot longer than my last marine battery. Anecdotal evidence to be sure. But when this one goes, I'll buy another one just like it.

Baller behindpropellers Posted March 30, 2015 Baller Share Posted March 30, 2015 Never have put a "marine" battery in any of my boats. Never really felt that a boat takes high shock loads. Maybe oldjeep takes his over the ski jump. Link to comment Share on other sites More sharing options...

Baller_ Wish Posted March 31, 2015 Baller_ Share Posted March 31, 2015 Biggest wave I ever drove a ski boat into was the result of a cabin cruiser on the big river. Thought I'd just power up one side and down the other. Forgot about the one behind it. Stuffed the nose of the boat straight unto the middle and took about 250 gallons over the windshield and onto myself and my wife. Course she was facing the other way and never saw the 56 degree January water coming over the top. But the battery survived as it ran the bilge pump for a long long...long time.

Baller TallSkinnyGuy Posted March 31, 2015 Baller Share Posted March 31, 2015 @Wish Good thing it didn't take out your windshield. I was driving boats for a summer camp back in '89 and one of the other drivers dug the nose into a wave and it completely broke out the windshield. Also almost completely filled the boat with water. I don't remember if we had to get a new battery for sure but I think most everything ended up being okay except for having to replace the windshield.
