Mini,
I used to think the same way about Everstarts. That was until i needed a replacment on the road and couldnt get one. When your somewhere like say vermont and your batteries croak on practice day for a two day and you cant get replacements because the only wal-mart in like a 100 mile radius is out of stock your screwed to say the least. The pro-rate charges suck too. The last time i had everstarts i could have easily paid for a set of trojans for what i paid out in pro-rate charges after the 12 month "free" replaecment on those batteries.
This exact scenario has has happened to me more then once over the years. The everstarts have not have a good track record for me, form a reliability standpoint they stink and service when(not an if but a when) they do fail has been almost non existant. Thats what sent me looking for a different battery and my trolling motor repair guy suggested the trojans. He could not have been more right. I put them in my 882 in 2002 and that was it for the rest of the time i owned the boat. $240 for 6+ years of good use is A-OK in my book, i just want stuff to work. They do cost more now but ~300 for another 6 years or so is fine by me. thats why i told the dealer when my new Z7 shows up just leave the batteries out of it and ill bring them 3 to put in, im going to do it right from the start.
