- Before the dry cell, batteries were literally open glass jars full of sloshing, highly corrosive liquid acid. If they tipped over, they ruined everything around them.

- This specific invention directly led to the creation of the portable electric "flash-light" in 1899, as well as the boom in portable radios, fundamentally untethering technology from the power grid.
