Milwaukee Tool MX FUEL XC406 Battery Brand New in Box

I have a brand new Milwaukee Tool MX FUEL Lithium-Ion Extended Capacity (XC) 406 REDLITHIUM Battery. The MX FUEL REDLITHIUM XC406 battery pack provides you with maximum power and runtime for all of your MX FUEL equipment in a compact profile, helping make MX FUEL equipment solutions the lightest and most powerful in the industry. This lithium-ion battery is capable of charging in as few as 90-minutes from fully drained to full power. This battery pack delivers fade-free power, running cool, even through heavy applications. An onboard fuel gauge displays remaining charge with the push of a button. The pack is ONE KEY compatible, allowing users and crib managers to track and manage this pack. This battery is fully compatible with all MX FUEL equipment. The battery retails $829 plus tax at Home Depot. So save several hundred dollars for a brand new battery.
