I'm going to start doing the same thing. I have went through all these high end break the bank batteries and don't find any of them to hold up any better than cheap ones. I bought two MACK daddy RV batteries for trolling motor three years ago, they are Deka's. Now they wouldn't pull a dead raccoon off the bank after about three hours on the lake.

I am not throwing any more of hard earned money away for expensive batteries...its just not worth it.
