I bought a reconditioned M12 1/2" Hammer drill last year from CPO. Came with a 1.5 amp-hr battery instead of the listed 2.0 (and 4.0 amp-hr battery). Called CPO, and had a new 2.0 battery in a few days. Didn't even ask for the 1.5 amp-hr battery back. As for the tool, it had a few scratches, here and there, but overall looked brand-new. Bought it for a father's day gift last year. It was on sale too at the time. So far, it's still working great for professional use. I'd buy more, though the price may not be different enough to justify the 1 yr warranty over a new tool's 5 year warranty...depends on the sale new-tool sales.
