How often do your batteries ditch you when are in the middle of some important task? Well, I bet most of the time. What if there was a way to know when your batteries run out of juice? Bringing to you just that perfect solution is designer Mac Funamizu, who has come up with an idea of batteries that tell you when they are hungry. Hailed as “Hungry Batteries,” the rechargeable battery concept start shrinking as it begins to run out of power. The reduction in size is an alarm saying “it’s time to recharge.” It stays just as straight as any normal battery when fully charged. When the battery goes thin, it becomes easier to take them out a packed battery room to recharge them.
