I bought a car battery from them. I didn't have much of a choice since no one has anything else on stock. The battery was defective with a bad cell so I returned it for another.
Then my second battery started dying. It mysteriously had lost 2 inches of acid in 9 months on a new and never opened top. Looks like it is leaking.
They denied the return and said it was my fault.
Two defective batteries. No more O'Reilley for me.
