Geeks are Sexy writes: "Microsoft has unveiled a technology which means batteries can be installed either way round. It’s already earned the backing of Duracell.
According to Microsoft, battery installation is the type of issue which doesn’t create many tech help calls and complaints, but still acts as a niggle. It also argues its creation will be particularly suitable for situations where batteries have to be changed in poor lighting such as in flashlights used by campers.
The system, Instaload, works with most cylindrical batteries that are commercially available, such as AA and AAA, including both disposable and rechargeable types. The technology isn’t used with the batteries, but rather with the battery-operated device."
