I have a Value line that is pushing 4 years old, but it's in a truck that doesn't get driven a lot, gets charged every month or two, and is in a mild climate. It was $56 when I bought it.What do you think of the Walmart Everstart Value 24F battery for 69.74 at Walmart. Some people have said they thought it was the same battery as the Everstart Maxx (just without the long warranty). Would it have the same real world longevity (5+ years) as the Everstart Maxx?
