DeWalt Bluetooth Batteries

DeWalt Bluetooth battery and toolconnect app

DeWalt Bluetooth Batteries launched in 2015 with Tool Connect App functionality. We saw them up close and personal at the DeWalt manufacturing facility in Charlotte, North Carolina. These premium 20V 2.0 Ah (DCB203BT) and 5.0 Ah (DCB205BT) lithium-ion batteries include Bluetooth connectivity to pair with the Tool Connect App. If you haven’t already, you can download the free app from either the Apple App Store or the Google Play store.


The tool innovation of a smart battery lets DeWalt users control their compatible batteries remotely using a smartphone or tablet. Users can turn a compatible DeWalt Bluetooth battery on or off, monitor battery charge level, view Bluetooth signal strength, and connect or pair additional batteries.


“Connected batteries offer some really tangible benefits out of the gate. DeWalt users can communicate with tools—via the battery—using a smartphone or tablet. We’ve also interviewed engineers and product managers who will be exploring ways to further maximize this feature as technology continues to fill the jobsite. The new DeWalt Bluetooth Battery and Tool Connect App present a big step forward in smart jobsite development.”

Kenny Koehler, managing editor, Pro Tool Reviews

The pairing of a DeWalt Bluetooth battery with the DeWalt Tool Connect app definitely has some real benefits on the jobsite.

What would be really cool would be to add a USB port to the batteries that could be used to charge your phone.
