I have a dual purpose Exide I got from academy just before they changed to interstate. I run a 998/helix7 and livewell pump from time I put boat in water till I take it out and have never had a problem. One thing I found when researching to buy that battery. And I consider this probably most important factor. I have 2 group 27 for troller because it’s all that will fit in my boat. The 24 dual I bought weighs the same as my 27 deep cycle which tells me it has some really heavy plates in it and should hold a charge just as long or longer than my trollers. So when making your decision on a dual purpose check the weight as much as anything else in comparing to deep cycle. Ideally if you can install it a good group 31 would be the choice.
