Time to replace the trolling motor batteries. Seeking advice on best marine deep cycle batteries?

Thanks in advance.

Hands down the best �bang for your buck�: https://www.walmart.com/ip/Everstart-Maxx-Lead-Acid-Marine-Battery-Group-29DC/49988415

The Best? In my opinion, the best would be either Northstar or Odyssey. Both are $$$ AGM batteries, but have lasting power and long life. My last set of Northstar batteries were 6 years old and still running strong when I traded my boat. New boat has 3 group 27m Northstar, so I really believe in them. I have heard a lot of good things about the Duracell 31 AGM (made by Deka) sold by Sam's for about $180, but don't have any personal experience.

My personal opinion any marine battery , keep em secured , filled with distilled H2O and tricked charged soon as you get off water , 24 / 7 . .

Every time the date on my Walmart batteries are three years old I swap them out.

For me they are the best value in batteries.

I did some in-depth research to find the battery most used by the pros. I figured these guys would use the best battery possible outside of being sponsored by a battery company. I found that Odyssey was that battery. Since I have replaced all of my batteries with the larger size Odyssey. In two years I�ve had zero battery issues. I�ve fished 12 hour days and never drained them. One other note is that I matched them with the best Duel Pro charger. After storing the boat I plug it in and never have to think about it. To me batteries are just as important as graphs and other electronic. They may one day save my life if the big engine fails. A great battery is a great investment. It�s the best purchase I�ve made for my boat.

I may never run these batteries down. I am 64 and don't tournament fish so I don't tire batteries as much as I used to.

I bought a couple batteries that came out of a Honda FIT(bought used on ebay). The batteries are Toshiba SCIB cells assembled in series to make a 68 volt battery. 24 20ah cells in each battery. I am using two of these to make batteries for my boat. Two for a 28 volt trolling setup and one for a 14 volt starter battery.
They are very long lasting with some good specs compared to anything on the market.
Lithium marine battery's that are out on the market are LifePo4's. They are good for about 2000 cycles. Mine are good for ten times that and the specs I've read are that after 15000 cycles they still retain more than 80 percent of their capacity. I should never need another battery. The trolling batteries should be around 55ah and the starter should be 37ah.

They cost 390 per car battery so 780 plus the cutting and wiring plus putting them in a waterproof box will put them well under 900 dollars finished.
A big plus? All together they weigh around 75 pounds.

They will be the best if I never need another battery. Not so much if they go down but you roll the dice.

Right here all the time. Mine have 3/15 on them and still going strong for my Ultrex. Take care of them and they'll take care of you and best of all, there's a Walmart everywhere.

Agree on the Walmart batteries. I�ve had them last 4-6 years. However, those were made by Johnson Controls. The serial number will start with JC. Recently they have been using East Penn, those pretty much suck. The serial number will start with EP. Try to avoid those of you can.

I found that out the hard way in one week replacing TM batteries and an auto battery. I had 2 new batteries out of the 3 were bad when I bought them. There were manufactured by EP. Had to replace them again same day.

Otherwise Walmart has a good warranty, no prorated just replaced.

Totally agree!! Currently have 2 TM batteries dated 7-2015

Every battery on my rig is Auto Craft from Advanced Auto. No problem...

Duracell AGM 31 series from Sam's club for $179

If money is no issue Odyssey. But they are twice the Duracell (Deka)

I agree, they are essentially just a re-badged interstate/duralast, all the same

He said "best". Not "bang for the buck".

Optima blue top group 31. The best I've ever had.

Walmart......yep! It's a battery for folks that don't know batteries.
