I've bought / used everstart max deep cycle battery's on my previous boat and they seemed to hold up well....... they're about in my price range ....... are they still a decent battery for the money??? .......

Also there is a batteries plus store near me that carries Duracell deep cycle battery's for the same price range...... anybexperience with these???

Any other options I should consider in the 100 price range???

had group 27 in the boat but have room to replace with group 29, is it benificial to do so?

I do 99% single pole fishing with the occasional trolling or visit to restricted HP lakes where I have to use my TM the whole time......... so my demands on the TM battery's are prob fairly normal / not excessive like trollers ...........

Thanks for all the info so far.
