The Batteroo Extends Disposable Batteries' Lives Up to Six Times

— February 13, 2018 — Tech
There are a battery of reasons why disposable batteries are in need of a reboot, and consumers can now create a better battery with Batteroo. The deceptively intricate sleeve fits around standard disposable battery sizes and extends their lives by a factor of six, saving the environment from electric waste and helping consumers save money in the process.

Batteroos are thin, low-profile metal sleeves that slip around the outside of batteries. They contain smart circuitry that makes batteries use up every last ounce of their energy. With stock batteries, voltage slowly decreases over time until the battery dies, but when batteries stop working there's usually still a fair amount of remaining energy inside. Batteroo defeats batteries' death wish and keeps them working longer.

Batteroos fit over AA, AAA, C, and D batteries, and at the thickness of a fingernail, Batteroo batteries should fit into virtually any device.
