Milwaukee M18 18-Volt Lithium-Ion High Output Battery Pack 12.0 Ah and Rapid Charger Starter Kit With Free 6.0 Ah Battery

You get what you pay for. Knockoff batteries do not last as long, both charge or longevity.

The Amazon description sounds like a great deal. Yes, there is a HD12 and a XC6 battery with a dual charger. The XC6 battery is not free as advertised. The dual charger can charger one of M18 batteries and a M12 battery. The M12 battery is a not part of the package.On the good side is that all three pieces are factory fresh and new. The shipping package was just a USPS box, no padding. I am lucky that the charger did not get damaged in shipment sliding around within the box.Next time I will read the description closer and save.

Came with a 8 hour and non fast charger but did come with the 12 hour battery so weird
