MPD is a licensed manufacturer of Microsoft's InstaLoad technology, allowing us to use this amazing technology in our battery contacts. InstaLoad eliminates incorrect battery insertions by making the battery work regardless of which way it is inserted. By using special contacts which have both positive and negative terminals instead of just one or the other, and a special circuit connecting these contacts, electronics users no longer need to worry about putting a battery in the wrong way.
