Is the Walmart Valu-power automobile battery for $50 any good?

I have heard it is as good as a $100 battery except only 1 year warranty. Anyway, I bought one and none too soon. The old one, which had been giving trouble, gave up for good stranding me except for the spare which I easily installed. It feels like a hot new battery. Old one was a quality Interstate lasted from 2014.
