Traditional batteries may never be the same again since Tetherboard displayed its working Tethercell prototype at CES 2013. It embeds Bluetooth into a traditional AA battery form. Control your batteries: power on/off.
What it is
A Tethercell battery is the size of a regular AA battery, but it holds an AAA battery inside its little case. It also holds a Bluetooth chip inside the case. This means you can use your smartphone to control the battery. When you change out a AA battery for a AAA battery, you will be sacrificing some capacity. Using the Tethercell in a device with multiple batteries helps to minimize this impact to battery life.
Tetherboard showed off a working prototype of the Tethercell at CES 2013. The company is currently talking with investors and tweaking the Tethercells to go into production. Pre-orders should be starting within a few days.
Why it’s Cool
Basically, Tetherboard is dragging old devices kicking and screaming into a new age of smartphone control. You can turn off little Billy’s toy guitar when you want to take a nap. You can disable your spouse’s remote control when you can’t stand another second of mindless channel-flipping. You can even set hours when a device can be used. The Tethercell could eventually be used to warn you when a battery is about to run out of power, saving you from your smoke alarm’s obnoxious low-battery wails at 4 in the morning.
