Do Not Buy Car Battery from Walmart Auto.why?
2017 bought car battery with 5 year warranty. Last week car battery doesn't work. Try to Walmart for warranty replacement. But Walmart Auto said replacement value is $25 and must buy same battery. We don't have same battery. So replacement is Not Possible.
And new battery price is $129.99
I got new battery from Sam's $104.

I will never buy Walmart battery.
