We recently went with another brand so I don't have use for my extra parts stock.

includes new (open box) OEM battery, part # 205-0011, 6 of the OEM high quality ultra-performance filters, one new rubber squeegee roller brush.

The battery has never been used - I bought it as new/open box over a year ago but just sat it on my shelf.  No doubt it will need a full charge before using.
