Normally when we buy batteries that aren’t specifically designed to be rechargeable, we simply throw them away when they go dead. A company called PC Treasures is bringing a cool device to the US called the Battery Engineer that might change that.

The device is a charging system that claims to be able to recharge disposable batteries as many as ten times. It supports multiple size battery charging and can charge four different batteries at once.

For the price at least they last awhile. At launch, Sony will release only battery powered glasses and apparently there are no induction-based models in the pipeline.
