The Black & Decker SMARTECH battery is a rechargeable, lithium-ion battery that adds Bluetooth connectivity and a smartphone app. It fits in any 20v Black & Decker cordless product—from drills and saws to hedge trimmers and vacuums—and, at $69, only adds about $20 to the cost of a conventional battery. Once plugged in, users can remotely check how long before they need to recharge, find a lost battery, or lock a tool to keep it out of the hands of a curious kid or neighbor.
