Watch This Wall of Dead Batteries Charge 140 Smartphones

A Thai soymilk company has figured out what to do with your old, dead batteries.

Vitamilk has teamed up with BBDO Proximity Thailand, an organization that focuses on brand and consumer relationships, to create "Dead Batteries for Dead Batteries."

Using the leftover power of 1,500 used batteries donated by the public, the team created a wall of batteries with the ability to charge 140 smartphones. A video shows the batteries being placed in a large wall in sections of threes, before users approach the structure and plug in their phones.

Vitamilk estimates that over the course of two months, the wall has provided smartphones with an additional 3,328 hours of talk time.

Maybe it's time to start saving more of those old batteries.
