Home Forums Fishing Freshwater Deep cycle battery preference ?

Really good article ,thanks

Thanks Kingston for that link. I learned a few things.

The Northstar with its thin-plate, pure-lead may the ultimate deep cycle battery for a boat's trolling motor. Amazon showed them and the price for a group 31 is a whopping $368!

I will stick with my Deka batteries which cost around $200 each, as I bought locally and can get replacement or warranty work etc easily.

FYI when using two deep cycles in series it is critical that they are a set. Never install one new one with an older one.

This applies to all batteries. Always float and finish the battery with your charger before using it. AND with vehicles, and I suppose the cranking battery for a boat, you should float and finish the battery with a charger every 6 months or so. An alternator will not finalize the charge of a battery like a charger. This will help extend the service life of the battery. Got that information from the Arizona representative for East Penn batteries.

I have three of these in one boat hooked in parallel to run a 55 pound Terrova I pilot and a minn kota endura. Lets me run sun up to sun down. I use this on lakes where you can`t even have a gas motor mounted on your boat. Never had any problems with these batteries.

In my new boat I have two of these. Interstate SRM-27 group size 27DC.
Can go all day running the same trolling motors mentioned above.

Optima or Northstar (X2 power from Batteries plus)


The pure lead batteries are heavier but supposed to be better - meaning the northstar batteries.

Wet cell battlerys (non AGM) fall apart due to vibrations and the banging when your moving fast.
