Battery     provides almost 50 hours (active mode) of battery life. The battery can easily be     recharged by charging system.       Close to the realistic color   To get the most close color as 2D, optical engineering technology was applied     in Nestri glasses lenses. LCD shutter lens has their unique color depending on     the manufacturing and liquid crystal mixing ratio. Nestri lens are very close to     normally white color.
