Get the battery from someplace that turns over stock (not TSC). You are better off with an auto parts store. I'm funny with batteries.
I look at the tops when I buy one. If it's dusty, I pass. reason why is all wet charged batteries, once the electrolyte is added, they begin their total lifespan so a dusty topped battery that has been sitting, waiting for a buyer, is in the process of petering out before you buy it.
I always buy my flooded cell batteries from a volume dealer. You know it's fresh then. Having said that, I never buy store brand batteries, always Interstate. With batteries, you get what you pay for and having a flat battery when you really need it is a bugger.
