How can You be sure Your buying the best trolling motor batteries ? I can't afford those that are real expense , i'm in the $ 125.00 price range , i usually get the one that's the most expense in that's price range & that may not be too Sharp.

I think this is another of those Ford vs Chevy debates. Everybody has their favorites. I just replaced an Interstate battery I bought at WalMart 8 years ago. I don't use my boat everyday which I'm sure contributed to how long it lasted. I paid $82 for the group 27 at WalMart. A battery with the same specs at Bass Pro is $150. Is the Bass Pro battery $70 better? I don't think so. It would have to last 80% longer than the WalMart battery. I'm going to have to replace my starting battery soon, it's 7 years old. I'm going back to WalMart.

There are only a very few battery makers in this country.  So a lot of what you might hear about are brands made by the same company.  Most batteries will get the job done and done well.  The main concern that you should have when looking at flooded cell batteries which are those in the price range you listed is RESERVE CAPACITY.  Get RC of 180 or more 200 if you can find them.  Don't worry about MCA or CCA just RC.  I have had lots of brands of batteries and found most all of them will do the job.

 

The second thing to look for is the free replacement warranty.  It should be at least 1 year.  That is OK because most battery malfunctions occur in the first 90 day.

 

Determine the size you need. either group 24, 27, 29, or 31. The bigger the better, BUT you need to have room in the boat and don't have issue with the added weight of a larger battery. Do you want a wet cell or AGM? Wet cells require periodic inspection and maintenance whereas an AGM does not, in the same token, the wet cells are normally rated for more RC and are generally less expensive than an AGM. Walmarts Everstart Maxx are pretty good bang for the buck. I repowered this spring with NAPA group 31 wet cells and they were about $130 a piece. 9=10 hours on the trolling motor and, according to the charger, they are at 50% at the end of a day. Not too shabby 

Thank's for the Help .
