Hi Ed; Walmart battery has two of those push in caps that cover three cells each. The caps in the Weskcar kit push into each of those cells separately. Some sanding on the cap bases might be needed for proper fit. Some push in with no problem. You might even be able to turn down some of the thread on your vented caps to 750" diameter to push in the holes of the Walmart battery. Info on mine that I bought here in Ontario : Maxx EverStart

I hope this helps. Go to Weskcar website for pictures and pricing of their product.
