Old Ironmaker Posted March 30, 2013 Report Share Posted March 30, 2013 I currently run 2 12V deep cycles marine batteries in tandem to power 55lb MotorGuide front mount trolling motor. The unit is floor pedal wireless remote control circa 1996. Have problems maintaining a good charge, lasted a few hours 2 seasons ago and now less than an hour and the remote isn't doing what it was designed to do. Unit rotates on command but is unresponsive for motor to start and stop without pushing the start button more than a few times. Batteries are 11 years old, I'm pretty sure they're done, bringing them in Monday for charge test. Trolling motor may have seen better days as well. Can't seem to get any answers for MotorGuide other than buy a new one please, a new 24V unit isn't in the budget right now. Might mention boat is 19.5' deep v Starcraft, full windscreen, 115HP Merc. From what I know 12V probably won't move the barge well. 55lb was probably max back in 96'. My questions are, if I need new batteries any recommendations? Does anyone know of someone in Ontario, GTA/Niagara/London, that might service MotorGuide? When charging should I select 5, 10 or 15 amp? I don't disconnect the cables that put them in tandem, charge each while connected to one another, make a difference? What is the difference between deep cycle and gel batteries,? never had a gel battery. Thanks for any replies, thought I'd ask now before everyone is out on the water.

moxie Posted March 30, 2013 Report Share Posted March 30, 2013 (edited) I run 2 Group 27 Interstates in parallel at 12 volts, charge at 10 amps with all wiring connected and into their fourth season they still punch out decent run time. Have gel house battery but offer no opinion vs lead acid. Start with new batteries. After 11 years of service it might be time to retire them.

MuskieWannabe Posted March 31, 2013 Report Share Posted March 31, 2013 Kirkland batteries from Costco, I think $105, 2 yr warranty, no questions asked, and work really well. All of my new batteries for the past 5 years have been them....the only reason for so many is that I have bought 3 used boats in that time and as the batteries die I put the kirklands in Link to comment Share on other sites More sharing options...
Fisherman Posted March 31, 2013 Report Share Posted March 31, 2013 If they are 11 years old, they owe you nothing and obviously you have treated them well. What brand/size are they, maybe you can get similar ones. If I was to go hardcore with a trolling motor, I would probably go with either the Odyssey or Deka brand, cost more, lasts longer.

hotsky Posted March 31, 2013 Report Share Posted March 31, 2013 (edited) +1 for Costco. I got one this past summer and it's been great so far. I just recharged it since havent had it charged in several months and it didn't even take that long to bring it up to full power again.

Old Ironmaker Posted March 31, 2013 Author Report Share Posted March 31, 2013 Thanks all, it's unanimous, the batteries are pooched. Charged them this am and both are down already. I will be looking at the Kirkland as replacements. Any thoughts on the MotorGuide unit? Link to comment Share on other sites More sharing options...
irishfield Posted March 31, 2013 Report Share Posted March 31, 2013 Probably work just fine when you put some new batteries on it.. lol Link to comment Share on other sites More sharing options...
Lunker Larry Posted April 1, 2013 Report Share Posted April 1, 2013 If you had a battery that lasted 11 years, I wouldn't change brands. What I use for deep cycle is Total Battery's Big Red.It is not light at 67lbs, but that means it has a lot of led in it. Never ever had issues with this battery. The one I use at the cottage is on its 7th year and going strong. Link to comment Share on other sites More sharing options...
bigbuck Posted April 1, 2013 Report Share Posted April 1, 2013 About trying your motor with a battery thats borrowed, one that a buddy has that is known to be good. That way you can see if your trolling motor is pooched. If not, pick up a pair of Kirklands and be done with it. Batteries need to be taken cafe of. Whatever you were doing, keep on doing it. 11 years out of deep cycles is pretty darn good. Link to comment Share on other sites More sharing options...
Sinker Posted April 1, 2013 Report Share Posted April 1, 2013 Another vote for the kirklands here.......great battery for the money. S. Link to comment Share on other sites More sharing options...

jedimaster Posted April 1, 2013 Report Share Posted April 1, 2013 Johnson Controls make good batteries. Sold by Costco, Walmart, Interstate etc... All the components are identical and come off of the exact same line. They are also the biggest supplier of OEM batteries. The sealed AGM batteries are the best, can be charged and discharge about twice as many times, as more shock resistant and provide a much flatter power curve. The flatter power curve gives you full power right until the end. Then they just cut out and die. Can be good or bad. Depending on how mindful you are. Just be careful not to charge them too hot.
