Throw those batteries away and switch to water powered devices! The DIY "Water Powered Flashlight" never runs out of batteries. Water powered batteries are still in the experimental stage, help build a brighter future by designing water powered prototypes! let's start to contribute to the eco-friendly community. The flashlight runs 30mins continuously with tap water and 2 hours with saltwater. Not bad for a single cell prototype :D Adding a second cell triples the glow and lighting time!
