I have just checked the packaging. It is 4676 mAh. I am very satisfied with this product.

Would buy simmer again works great so far no defect and the battery brings a lot of runtime

The official answer from Meta is no. I don't think it works because of the mounting. There may be an adapter for the 3d printer.

Yes, it is written in the product details in the warranty section.

It's only a more confortable head strap with a extended batterie. The VR headset is not included.

No, unfortunately there is not. You would have to take the variant where this is explicitly written. This variant does not include a carrying bag or similar.
