Microsoft unveiled a "new technology called "InstaLoad battery installation technology," which allows users to easily install a battery without regard to positive and negative polarity. Never again will people have to squint to see battery installation diagrams — the device simply works regardless if the battery is installed positive-side-up or positive-side-down. InstaLoad is a patented battery contact design now available for license by third-party device suppliers, with companies like Duracell already lining up to endorse the technology for use in their own products," said Microsoft.
InstaLoad can be incorporated into devices that require frequent battery swap-outs. The tech is compatible with popular off-the-shelf batteries used in products such as flashlights, toys, battery chargers, lighting and most other battery-operated consumer electronic devices that use CR123, AA, AAA, C or D size batteries (disposable or rechargeable) or similar barrel-type battery form factors.
