Now you can place the Battery in the direction which you like.

InstaLoad is a new battery technology from Microsoft that gives devices power, regardless of how users insert the batteries. It doesn’t matter which side is positive or negative; the device will simply work.

The technology is in the mechanical battery contact design. Each side of the metal contacts in a device have positive and negative points, rather than just a positive or negative point.

The technology works with most barrel-type batteries, so your AA, AAA, C and D batteries are all compatible. It also doesn’t matter whether the batteries are rechargeable or not.
