Like many of you I have used verious brands of batteries over the years. I must agree that Wal-Mart batteries are crap. I have never gotton more than three years out of one in a daily driver. I bought a wal-mart Deep Cell four years ago and and only used it twice. I have used a tender on it and now it will only charge to a 65% rating. I completely drained it with a trolling motor and attempted to recharge on a low setting, same thing 65% I started buying Die-Hards from sears and have alway's gotten the full month plus rating from them. I know they are not made by sears, however I like doing buisness there. I really have no complaints about them. I plan to replace the batteries in my 07 Diesel with them.
