I have not used any of the expensive batteries. From the reports, they seem to work pretty well.
I have used quite a few of the 'Johnson Controls' batteries and have found the following:
They for the most part are decent batteries. They have given me good service, but like others have stated, need to be replaced occasionally. Other than gel batteries, almost any battery is going to be affected by rough riding. For me, that hasn't bee a problem, for if it's real rough, I either slow down or don't go out. Simply a personal preference.
Like Me!, I like that if needed, I can go to any WalMart and get a replacement. I put one of their big yellow marine batteries in my boat last year (cranking battery), and it has performed very well - including in a night tourney (two nights). I will be replacing the two trolling motor batteries this spring with Everstarts. I like the ease of getting them, and the cost.
If you need absolutely near fail proof, long lasting batteries, and have plenty of money - try the gel batteries. If you are like most of us, and have to watch the pocket book, try the Everstarts.
Always check the deminsions (including the height), to ensure new ones will fit properly. And make sure your electrical connections/cables, are of the highest quality and correct size.
