deep cycle marine battery help please

[PACKFAN]

I run Interstate in all my rigs, 5th wheel, Lance camper and my Crestliner. I pretty much fish for walleye so I do alot of trolling with my 80 lb. thrust Minn-Kota. I can get a days fishing in without a charge depending upon how much wind I'm fighting. I have been getting 5 to 6 years out of my trolling batteries. I have had good luck with them for the past dozen years or so. The last set I bought several years ago run around $75 each. Always replace the whole set of batteries when you change them out if you run more than one.
