Microsoft now licensing InstaLoad battery tech
Microsoft has developed technology which allows installing disposable cells without concern for positive or negative polarity. Called InstaLoad, the battery installation technology uses new contacts that can take a charge regardless of the battery's orientation. Microsoft sees ideal applications of InstaLoad in devices that require frequent battery changes, use several batteries or are used in harsh environments.
Microsoft's solution is entirely mechanical, so there is no added power draw or required costly hardware. The technology simply replaces existing battery contacts and can be fairly easily designed into the existing battery compartments of devices. Compatible battery sizes include CR123, AA, AAA, C or D size batteries, whether disposable or rechargeable.
The technique is patented, and Duracell and AE Light are in line to license the technology and use it in their own products.
