BillAV8R1 Posted August 11, 2020 Report Share Posted August 11, 2020 I'm going to be purchasing a Minn Kota Terrova 112lb 60" or 72" trolling motor for my '16 2200 TRS and I'm looking for battery brand and size recommendations. I know I need three of them, but not sure what size/series to get. I've been looking at Optima blue tops and Odyssey batteries. Any suggestions/thoughts would be greatly appreciated. Thanks - Bill Quote Link to comment Share on other sites More sharing options...
Miss Jazzy Posted August 11, 2020 Report Share Posted August 11, 2020 I can tell ya there are better choices than optima. For the price they should last forever but I’ve had to replace both of mine within two years. Never will I buy another. Others will give you several ones to choose from but for the money I would buy from Walmart/Sams. I had them on my Jon boat and never had an issue nor did I run them down.

jh141 Posted August 11, 2020 Report Share Posted August 11, 2020 I use Deka Intimidator AGM Group 24 (8A24M). I have three in a custom box in the console. Never have run out of power. I do have a Stealth 1 ac/dc charger and that may allow me to get by with group 24s, but I do not think so. They last an average of 5 to 6 years. My House 1 battery is a Optima blue Group 27 and I am replacing it very soon. Not impressed. I had a MG Xi5 36 volt and now have a Rohdan 36 volt. Can Not go wrong with Deka AGMs. Dekas are also labeled with other names. Do your research. Quote Link to comment Share on other sites More sharing options...
fin-addict Posted August 11, 2020 Report Share Posted August 11, 2020 Walmart, 27 series. Can’t beat the price and they last several years Quote Link to comment Share on other sites More sharing options...
wthree3 Posted August 11, 2020 Report Share Posted August 11, 2020 Odyssey or Northstar or X2Power ( rebadged Northstar from Batteries Plus) are my preference in premium AGMs. I get 8 to 10 years out of them before they start to slowly degrade. Never had a sudden failure. I use group 34M. M version has dual terminals, one set being threaded studs. One other benefit of AGMs over flooded batteries is that AGMs don't off-gas and therefore your terminals and adjacent hardware won't corrode.

Bamaskeet Posted August 12, 2020 Report Share Posted August 12, 2020 If you follow the RV guys, they swear by SAMs Duracell AGM group 31 batteries for less than $200 ea. I’ve been running them for over five years with great success. Quote Link to comment Share on other sites More sharing options...
smilemaker Posted August 12, 2020 Report Share Posted August 12, 2020 the battery manufacturers make it difficult to truly know the difference between name brand and rebranded varieties. one general belief is that the name brand is made from better quality of lead and the rebranded versions are recycled lead. The name brand will usually have a longer warranty and I personally believe that is the reason for higher cost. Just like buying a extended warranty. I would look at the specs and make a choice of agm batteries. Quote Link to comment Share on other sites More sharing options...
bernieNC Posted August 12, 2020 Report Share Posted August 12, 2020 OK, here goes. I am not on the AGM train. They cost and weigh more (an in a lot of cases less "juice"). If you look at specs most good wet cells have more RC. I use wet cell Interstates in all of my boats. This spring I switched out all the batteries in the Pathfinder after SEVEN years (and they had not failed). I did go from group 27 to 31 on the TM batteries only because the price difference was minimal. I have seen ZERO corrosion or any issues due to out gassing but the Pathfinder console does have plenty of air movement. Sure, I do have to water them a few times a year but that affords me the chance to check connections while I am in there. I do have a Stealth AC/DC charging system which I believe has a lot to do with the the performance of the wet cells or for that matter any battery.

smilemaker Posted August 12, 2020 Report Share Posted August 12, 2020 you can outgas an agm battery as well. they have a pressure releif valve . In my opinion location and ease of access is the only reason to go agm. Do to space constraints and manufacture desire to make things look neat agm are more practical for the average boater. improper charging is the biggest demise to any battery.

Miss Jazzy Posted August 12, 2020 Report Share Posted August 12, 2020 Do y’all keep your chargers plugged up at all times? I do but I have heard of people that won’t saying they will hurt the life. I’ve never had an issue. Quote Link to comment Share on other sites More sharing options...
fin-addict Posted August 12, 2020 Report Share Posted August 12, 2020 I have no problem with out gassing in console or rear hatch where start batteries are located. Was told a few years ago that all batteries are made by three companies and different labels are used by the other companies who purchase them. How true this is I don’t know.

Dry Stacks will not let you charge batteries inside the building because it is considered a fire hazard (think about it). Quote Link to comment Share on other sites More sharing options...
