Perhaps this is old news to some but I just noticed that my local Walmart's auto batteries almost all appear to be East Penn built; fully sealed, maintenance free.
Also, the Everstart Maxx have higher CCA and better 3 year free replacement, 5 year pro rate warranty yet are only a mere $5 more than the next step down.
Personally, I never liked vent cap batteries such as built by JC, they always seem to leak acid, sometimes a lot of acid and can damage the under hood sheet metal if not caught in time.
