Wal-Mart may have the most liberal return policy in retail, but the
warranty is probably going to amount to 20% of the original price,
assuming 5 years.
I would just take it back to a WM with an auto service center and ask
what they will do for you, preferably still installed in the truck, if
possible.
I wouldn't try to bullshit them, you don't have a receipt so you are
at their mercy, and I would approach it from that perspective.
When it comes to batteries, there aren't a whole lot of good options.
